DIY metal entrance door. How to make a metal and iron door with your own hands. Door frame design

A do-it-yourself metal door often surpasses many factory samples in both quality and reliability. It’s not without reason that they say that a house is a small fortress, and Entrance door- fortress gates. And it’s difficult to add anything to this. After all, if entrance doors are ordered at the market or in a supermarket, this is not a guarantee that the doors are of high quality and reliable. On the other hand, often the situation associated with the need to weld and install a temporary structure for the period of repair makes the idea of doing everything yourself quite realistic and relatively cheap.

DIY metal door - from idea to practical implementation

Conventionally, an independent embodiment of an idea put together from sets metal pipes, plates and corners, a real metal front door does not require extensive plumbing experience. True, we must immediately admit that assembling a metal door with your own hands will present certain difficulties. But with thoughtful organization of work and the availability of tools, many mistakes can not only be avoided, but also corrected in time.

The first step is to determine what kind of structure it will be:

a lightweight temporary structure for the period until a real armored door is purchased;
a structure that is planned for construction for a certain time as an entrance door to the corridor from the landing;
a normal entrance door to an apartment or house with insulation and a reliable lock;
a monumental structure for centuries with the firm confidence that the door will protect against any vandals.

Based on this, forces, time, and necessary materials. The entire process of work is planned from taking measurements to installing external and internal lining doors. Conventionally, a door from a profile pipe is created with your own hands in several stages:

initial stage - taking measurements, preparing a drawing, selecting and ordering materials, preparing tools;
stage of development of individual components and connections, preparation of a slipway or assembly table for work;
creating a door block, welding doors, fitting, installing locking devices, installing metal sheets;
installation of a door in a doorway, fixing, finishing;
installation of cladding and internal filler, adjustment of systems.

Although this scheme of work contains a large number of points, but at step-by-step implementation their excellent results will be guaranteed.

Preparatory stage - where to start

It is not difficult to guess that an iron door is created with your own hands from metal pipes, angles, channels and sheet metal. But you should start by organizing your workplace and selecting tools for the job. It’s worth remembering that you can’t have enough tools. Having always learned to work with one tool, it turns out that it is more convenient to use several more tools for work. So for normal operation you need to prepare:

metal ruler, scriber, tape measure, metal square, crayons;
grinder with a set of cutting, stripping and grinding abrasive wheels;
with a set of metal drills and a center punch;
welding machine, here it is preferable to choose an inverter, it is today optimal choice for newbies;
hammers of different weights;
files for metal - triangular, round, square, flat;
magnetic holders - multi-profile, with a mandatory angle of 90 degrees;
clamps, clamps, clamps;
Be sure to wear a welder's mask and gloves for working with hot metal.

The next point is organizing the workplace, because before you weld a metal door yourself, you need to at least prepare a platform for laying out all the elements for fitting. It is ideal to have a mounting table or workbench for this, but you can first prepare a simple flat area on concrete or OSB.

A do-it-yourself metal door will require the following materials:

metal profile 20x40 mm - 22-24 linear meters;
sheet metal - 1x2 meters with a thickness of 2.5-2.8 mm;
hinges for fastening the door with bearings;
lock with overhead handles;
to fill the internal volume;
insulation and material for external and internal door cladding.

Marking and preparing parts for assembly

At the stage of preparing parts, the design of metal doors, a drawing of which is drawn to scale, is drawn in the form of separate drawings - the elaboration concerns how the parts will be attached and what the sequence of work will be. Detailed drawings make it possible to minimize errors and waste when cutting metal.

When transferring drawings to metal, you need to clearly understand how a metal door is structured, which elements require special precision, and for which it is necessary to make a gap of 1-2 mm. For the door frame, it is important that all parts are made with the smallest deviations, especially if the profile pipe will be butt welded along 45 degree cuts.

The first step is to prepare the door frame. Tolerances on the outside should be no more than 1 cm in relation to the doorway. And here inner part must be ideal in all planes.

A do-it-yourself metal door, the drawings of which are developed taking into account the installation of safe locks with fixation at several points on the block, must be reinforced with an internal frame made of a profile pipe or corner.

In the process of laying out the door block parts on the assembly table, the installation location is determined:

anchor bolts for fastening the block to the wall;
door hinges;
key holes and fixing the safe mechanism;

Even before welding the hinges to metal door and connect the block into a single structure, it is recommended to drill the necessary holes in the profile, and only after that proceed with final assembly.

Door block assembly

When creating a metal door with your own hands, assembling the door block and the frame of the door itself have a lot in common. In both cases it is an assembly of simple rectangles. Assembly technology using welding joints of profile pipes at an angle of 45 degrees provides for:

preparing a profile with pre-cut corners;
laying out all the parts in one plane;
check internal corners door block;
with the help of several touches of the electrode, the structure is literally seized into one whole;
using a square, the correctness of right angles is checked, and internal diagonals are measured with a tape measure;
the entire structure is welded with a construction seam.

Before welding a door from a profile pipe, the finished door block is tried on in place of the opening. Next, using a stripper and grinding wheels The grinders remove the beads and form beautiful, even seams.

Door frame assembly

A do-it-yourself entrance door made of metal is welded using the same technology as the door block, with the only difference being that its dimensions must be as accurate as possible from the outside of the structure.

In fact, the door block in this case can be used as a template for laying out parts and fixing the frame before welding. The first step during assembly is welding the door hinges. The parts are adjusted so that at the top the gap between the block and the door itself is 2-3 mm, but at the bottom the gap needs to be made larger - up to 3-5 mm. When using simple garage hinges in the design, they need to be welded on top of the frame and block. For hidden mounting hinges, it is necessary to provide extra space in the door block. To do this, it makes sense to make the side where the hinges are attached from a pipe of a larger cross-section. A gap at the bottom of 5-7 mm between the door and the block is needed because the armored door is welded with your own hands from 3-4 mm metal, and the weight of the door over time causes wear in the hinges, gradually lowering the door.

After welding the hinges and guide, we begin welding the frame of the door itself. The door block is placed horizontally, on flat surface. Using a level, its position is checked. Pipes, cut to size using wooden planks, are laid out level inside the block. The gaps between the door frame and the block are established using wooden wedges or plastic crosses for installing tiles.

Further, as with the block, temporary fixation is carried out with individual points. After checking the corners and diagonals, the final welding of all elements into one unit. After welding the door frame, the entire structure is raised and checked in a vertical position. If the door opens and closes easily without touching the block, you can begin installing internal struts and locks.

When forming the frame, all elements must be fixed in one plane. Metal tends to deform during welding. As a result, homemade metal doors made with your own hands turn out to be curved.

Installation of a lock and locking hardware

There can be no trifles in the question of how to weld a metal door with your own hands. Especially when it comes to safety. Installation of the lock and safe hooks must be carried out during the manufacturing process of the door frame.

Until the frame is covered with a metal sheet, it is convenient to make holes in it and install a lock. When placing the lock, you need to keep in mind that an armored door, like any other, can be lowered during operation. This means that the locking mechanism should be placed so that when the door is lowered, it cannot jam.

The gap between the bottom of the lock tongue and the bottom of the hole in the block must be no less than the gap between the door and the threshold of the block. Marking on the door frame mounting hole this fact must be taken into account. Alternatively, you can cut an opening in the door frame to the size of the lock mounting plate. Then, simply make a mounting strip from a metal strip and weld it into the body from the inside.

The second installation option involves making a slot in the door frame pipe and processing it with a file until the right size. However, the lock may prevent the door from closing. It simply will not allow the door to close if the gap between the frame and the block is less than 4 mm.

Installation of metal sheet

The final stage of assembling the metal door structure is installing the door tightly onto the frame. The marking of the sheet is carried out last, when the entire structure is ready.

Before welding a metal door into the final structure with your own hands, it is recommended to attach the block to a sheet. Circle it with chalk to visualize how much metal needs to be removed and from which side.

When installing the sheet, the external loops must also be outlined. Because you will need to specially cut openings for them in the sheet.

Having adjusted the sheet to size, it is installed on the mounting table and the door frame is placed on top. Welding is carried out with reverse polarity, the fact is that when using thin metal, it simply begins to deform or at the welding sites, a burn-through is formed - a hole in thin metal. When changing the polarity to inverter device the risk will be significantly less.

Welding of the sheet and frame is carried out with thin electrodes with a diameter of 2 or 2.5 mm. Never use electrodes with a diameter of 4 or 5 mm. Welding is carried out in one direction - gradually pressing the sheet to the frame. The length of the welding seam should be no more than 1.5-2 cm. In this case, the distance between the seams should be 5-6 cm. When welding a sheet and a pipe, welding is done on both sides of the pipe in a checkerboard pattern.

Making a metal door with your own hands - video

Today, not only city residents, but also the majority of country property owners prefer metal constructions. In theory, they are much stronger, more reliable and durable than their wooden or plastic counterparts. But in fact, many solid-looking metal doors from the budget segment can be opened with a can opener, and a crowbar for them is universal key. Not everyone can afford to install a massive, expensive structure, and high cost is not a guarantee of appropriate quality.

Therefore, craftsmen with skills welding work and the corresponding tool base, they prefer to make such doors themselves. In this situation, you can be confident in the strength of the frame, and in decent parameters of noise absorption and thermal insulation, and also give the appearance in the general style. FORUMHOUSE users have also mastered the process and are sharing the results. We study their experience and prepare a metal door.

Experience is the best assistant
Useful tips for beginners from experienced ones

Metal entrance doors - constructive

In a typical version, a metal door consists of a frame, a leaf, hinges and mounting elements (plates, eyes, pins). You cannot do without certain costs for materials and components, but a self-made door will cost much less than a purchased one. The exact list of consumables depends on the design, dimensions and purpose - if for a simple frame with lining and a latch, then to enter the house the door must be multi-layered, with effective locking fittings and decorative cladding. In the second case, an approximate set of what is needed looks like this:

Metal corner (from 5 mm) or profile - for the box;
Metal corner or profile pipe - for the frame, stiffeners;
Sheet of metal - for power sheathing ( optimal thickness 2-3 mm).
Thermal insulation material (mineral wool, polystyrene foam, EPS or PSB);
Components – hinges (preferably with bearings), seal, peephole, lock/locks, handle, etc.;
Finishing – wood, forging, plastic (for inside various panels or laminate).

One of the most important stages– measurements; if you make a mistake, installing the door in the future will be significantly more complicated, so you should adhere to certain recommendations:

All measurements are taken not from the finishing layer, but from the rough wall;
There should be a groove left between the frame and the opening, the standard one is 2 cm (for alignment and installation seam);
The gap between the box and the canvas on the hinge side is 3 mm, on the lock side – 5 mm.

Having a working drawing with dimensions or at least a sketch will be a good help; not everyone’s imagination is developed enough to imagine the end result in their mind. Fortunately, there are plenty of quite workable drawings on the Internet, although drawing and drawing are also difficult.

Experience is the best assistant

But the best assistant is the experience that the participants of our portal generously share.

A 20x40 mm profile pipe was used for the frame, a metal sheet 3 mm thick, insulator – mineral wool, finishing – MDF.

Since it is necessary to cook the frame on a hard, flat surface, and the craftsman did not have a suitable cooking table, he used beams placed in the same plane. He also used clamps to maintain the geometry of the product; some of them slightly “grab” the elements to the cooking table during the welding process. dronduletus I made the door in several stages.

I cut the pipe to size, did not observe the 45⁰ angles, since the welding was carried out end-to-end, assembled the frame, beat off the diagonal, grabbed it, checked it, and secured it with clamps. I welded the frame and welded the stiffeners.

The sheet for the sheathing was cut taking into account allowances for overlap along the entire perimeter (1.5 cm), and secured to the frame with clamps. I first welded it from the inside of the frame - from the middle to the edge, using clamps (about 2 cm in increments of 15-20 cm). To make the sheet less flexible, cook it diagonally - opposite sides in different directions. Afterwards, I welded the external seams in the same way, cleaned them with a grinder, and welded them along the stiffening ribs in the same order. It was possible to get by with just one rib, but the sheet turned out to be curved. Next, I welded the “pocket” for the lock - I cut a groove in the end, and scalded it around the perimeter with profile scraps.

I made the box from a 40x40 mm corner, used a 100x50 mm channel for the threshold, and when cutting the segments I added gaps not only for the hinges and the lock, but also up and down (4 mm each). As a protection against those who like to profit from other people's goods, I welded additional plates/plugs over the place where the crossbar will fit the full width (on both sides). I welded metal strips to attach the box to the wall (two on top and three on the sides). It protected not only from knocking out the bolt, but also from removing the door from its hinges.

dronduletus

I welded pieces of corner 8 cm wide inside the door, on the back side of the frame, lifting it 8 mm from it - these are anti-removal crabs.

I welded the canopies in a horizontal position - placing the canvas in a box and placing a 2 mm thick steel plate between the canopy and the canvas, so that the seal could be glued on afterwards and avoid friction. I welded the canopies at a distance of 25 cm from the edge of the canvas to the center of each canopy, having previously checked the level and secured with clamps.

Since the walls are old and leave much to be desired, I abandoned conventional anchors and used pins only to fix the threshold (channel). The frame was secured with studs 25 cm long (diameter 12 mm) and chemical anchors. After installing the frame, I hung the door and drilled holes for the bolt. I laid insulation in the door cavity and sewed everything up MDF panels, painted.

Another portal participant did not photograph the process, but his observations will be useful to anyone who is planning to start making a door.

I also welded the doors; I didn’t take any photos during the process, but I’ll tell you the details. I did this with my father-in-law, they welded a bunch of these doors as a sub at the factory.

DIY metal door, life hacks and conclusions:

It is better to take hot-rolled iron for cladding; cold-rolled iron has tight geometry and right angles;
To weld the hinge plate to the box with a clamp, you need to hold it lightly and immediately release it. When the seam cools, the plate will bend with the required gap. All loops are scalded after fixation;

If you make a special device (as in the figure), pressing the sheet to the corner during welding will avoid “bubbles”;

To prevent the door leaf from touching the frame during operation, the hinges are welded so that the hinge axis is on the edge of the sheet;

Intermediate draft result in the photo.

Master81 welded two metal doors - double-leaf and single (255x110 mm and 210x0.72 mm), and, looking at his creation, it is clear that he is “on the short end” with metal.

The box was welded from a corner five millimeters thick, six is possible, but four is undesirable, the frame is made of a 40x20 mm profile pipe. The manufacture of the structure did not cause any difficulties.

I measured the doorway, minus a centimeter from the width and length, cut the corner straight with a grinder, first assembled the frame, then the frame for the door.

Another one of our craftsmen, FORUMHOUSE member from Moscow with nickname oss, has already made the sixth metal door, if you count Garage Doors. The canvas is three millimeters thick, the frame is made of a 50x40x3 mm profile pipe, like most, but he approached the issue of safety thoroughly. Armor plate, internal plate, lever lock with four bolts, protective curtain in the hole. These improvements have increased the cost of the product, but peace of mind is more valuable. No photo oss compensates with an optimized assembly process and useful tips.

Before this, I made doors using different techniques, including first tying, and then tacking and assembling the frame. The sequence chosen this time seems more optimistic.

The optimized version looks like this:

I started with the front vertical profile, made a frame, secured the lock in the frame, checked how it worked;
I made a rear vertical profile, immediately welded the anti-pullers (behind the hinges);
I assembled the entire frame from profiles using tacks;
I cut out the trim along the frame (with an overlap of 20 mm);
“I baited” the sheet, scalded it with oven mitts in increments of 150 mm;
In the racks of the box (trimming) I cut out grooves for the crossbars and anti-removals;
I welded a box with gaps (3 and 5 mm);
Welded the hinges.

ABOUT ss advises to insert one combined door lock instead of two different types.

Conclusion

In a thread on the forum dedicated to, the opinion was expressed that the costs of homemade products would be significant, and the savings would not be so significant that the game would be worth the candle. However for skillful hands and the manufacturing process is quite feasible, and the ability to choose decent materials, and not guess what’s inside the purchased structure, is an important factor. Therefore, while some are talking about the feasibility, others are doing and sharing real experience to make the task easier for beginners.

How to save on entrance fees wooden doors, you can find out from the article - also on our portal. The video contains an overview of popular new doors from the famous exhibition.

It's no secret that today such an element as a metal entrance door is not a luxury, but a mandatory attribute of any residential premises, including a private house or apartment, as well as various administrative and office buildings.

Thanks to the modern development of technology and the emergence of innovative materials, you can personally design any, even the most complex, item needed in everyday life. A metal door is no exception: if you have some construction skills, you can easily equip this element yourself, thereby saving yourself from the need to overpay for the installation of a ready-made model. In addition, it is much more pleasant to arrange your home at your own discretion, without using templates. Therefore, we should take a closer look at how competently it should be. But first, you should pay attention to the list of advantages that this functional part of the house has.

The main advantages of a metal door

Thanks to the ability to use modern materials for insulation, this element can provide excellent protection from noise and from cold entering the room, which is especially important in cold climates. Insulated metal doors are a guarantee that you will not freeze in your home.

Another reason to create such an irreplaceable attribute of everyday life with your own hands is an excellent appearance, which makes it possible to turn a seemingly standard part of the home into a unique and unique element with high aesthetic qualities.

Perhaps the main advantage of a metal door is its high resistance to burglary, coupled with the possibility of installing additional security measures (various limiters, etc.). This will completely protect the home from the entry of unwanted persons and will save the nerves of its owners.

It is these advantages that are the key factors influencing such a decision,

Doorway measurements

As with any other task, you must first complete everything necessary calculations. When making an element such as a metal door, you first need to take measurements of the opening with your own hands. The door leaf and frame will be designed in accordance with them. It is important to remember that it is extremely important to subtract 2 cm from all the parameters obtained during the measurement process. This small gap will subsequently make it possible to adjust and align the door in the opening. Measurements must be taken for the entire length and width of the desired hole, that is, starting from the base in the form of brick or concrete, and not from plaster. It needs to be done this way because finishing material can be applied in a thick layer, and if the parameters are incorrectly calculated finished door may not coincide with the actual indicators of the installation site.

Tools and materials for work

The equipment required to make a metal door yourself includes the following set of tools:

welding table;
an angle grinder equipped with a metal wheel;
welding machine;
screwdriver;
drill with several drills;
tape measure and other measuring instruments;
and screwdrivers.

As for the actual materials that will make up the door, their set is as follows:

metal corners for the box or a steel pipe with a square profile;
sheathing material in the form of plywood, veneer, boards, etc.;
metal sheet with a thickness of at least 1.5 mm;
door hinges;
accessories (handle, locks);
fastening elements (screws, bolts, etc.).

Door frame design

It’s absolutely possible to do it yourself, and all the work should start with making a box for it. This element consists of securely welded corners, which form its basis. It should be remembered that after installing vertically and horizontally located parts, it is necessary to leave gaps that will be required in the future.

On welding table you need to place a corner or square-shaped profile and cut it according to the required parameters. The finished parts need to be laid out in a rectangle and all the parameters must be checked again.

It is very important that all angles are exactly 90°, so you need to carefully study the diagonals, measuring the distance from one end to the other. Once all calculations are completed, you can begin welding the door frame. At this stage, it is allowed to make slits in it. For this, use a grinder.

When installing an element such as a metal door with your own hands, the drawings must be made as correctly as possible so that the design fully complies with the pre-drawn project. Otherwise, the result of the work may not be at all what was originally expected.

Door leaf installation

First of all, you should clearly determine the size of the potential canvas. To do this, you need to measure the parameters of the inside of the box and leave a gap of about 0.5 cm on each side. It is based on these indicators that a metal door should be made with your own hands, the drawings for which, in turn, help to complete all the work as quickly and efficiently as possible.

Next, you need to weld a frame consisting of corners intended for the canvas. The process of making it resembles in its actions the creation of a box. From the inside, parts of the corner must be welded to the frame at the same distance from each other. These elements will serve as stiffeners.

The next procedure that should be performed when making a house element such as a metal door with your own hands is to cut out a steel sheet. It must correspond to the parameters of the frame, and it is extremely important to maintain an allowance of 1 cm on each side, as well as 0.5 cm on the side of the hinges. This sheet must be welded evenly to the door base, while not forgetting to remove any burrs that appear and correct uneven seams using a grinder. At this point, the manufacture of the door leaf can be considered complete.

Fixing a metal door on hinges

These elements must be welded according to a special scheme. As a rule, one of the hinge parts, which has a special pin, is first attached to the box. Its second part is fixed directly on the canvas. It is very important to pay attention to the drawing of the metal door, according to which you should correctly calculate all dimensions and measure the required distance for installing the hinges.

It is necessary that both of these functional parts match perfectly. This will not only avoid distortion of the entire structure, but will also improve its tightness and extend its service life.

When installing insulated metal doors, do not forget that for laying insulation it is also necessary to leave some free space inside the door leaf. This procedure will be more complicated, but such a measure will definitely protect the entire structure from the penetration of cold.

After installing the hinges, you need to clean the seams if necessary, and then paint the finished structure.

Equipping a metal door with fittings

When thinking about how to make a metal door of the highest quality, you should not forget that to create a reliable model Special attention it's worth paying attention to this important matter, such as installation and fixation of the lock mechanism.

For this work, you will need to purchase two different types of samples, which during installation should be positioned as conveniently as possible. It is very important that each of the elements of the lock fits the other, and that the entire system interacts smoothly and easily. A drawing of a metal door, of course, cannot reflect this, but it will be much better if the mechanism does not create unnecessary sounds (creaking, grinding, etc.) during opening.

After this, it is recommended to cut a special hole in the door leaf, intended for the installation of a good and modern door peephole, having a wide viewing angle and, if necessary, closing. At this point, work with fittings can be considered completed.

Installing a metal door in an opening

To insert a ready-made door structure into the opening, the strength of at least two people will be required, since it will be problematic to do this work alone. In addition, you need to pay special attention to the following points:

The box should be positioned geometrically evenly. All measurements can be taken using a building level.
The structure must be fixed securely and tightly.
All gaps formed between the wall and the door must be sealed using polyurethane foam.

The installation of the metal door is completed with another check of the reliability of the lock mechanism. In addition, you should make sure that the system opens in the desired direction easily and without any interference and closes just as easily.

A good addition to the aesthetic appearance will be the device as well as the design of its slopes. Such procedures will not only make the structure more beautiful, but will also increase its specifications, improving thermal and sound insulation.

Working with such a modern and necessary attribute of the home as a metal door, you can not only make the model itself with your own hands, but also decorate it beautifully.

Here, as always, the basis of the design is solely the preferences and tastes of the owners, but we should not forget about this important factor, as operating conditions, since it is not always possible to decorate different doors in the same way due to some external factors: climate, type of construction, etc.

As an option, you can use veneer or MDF; polymer painting is also suitable. This type of finishing, such as covering the door with a special film that protects against external mechanical damage, is also gaining increasing popularity.

One way or another, a metal door can be designed in different ways, but the main thing is that this element clearly performs its functions and is able to serve for a long time and reliably.

Sections of the article:

Reliable metal doors are used virtually everywhere. They are installed not only in apartments multi-storey buildings, but also in private households, bathhouses, and various outbuildings. In addition to purchased ready-made options, some people prefer to create a homemade design, for which a drawing of a metal door will be a good help.

It is not always possible to purchase a steel door leaf and door block of proper quality. The first problem is the pricing policy of the modern construction market. The second problem is that sometimes the doorway is very specific and doors for it are made only on an individual order.

There is a simple way out of this situation. If suitable products practically not on sale, you can always make them yourself. The metal door has simple design, which is quite possible to make with your own hands. There are various drawings and much more for this. Homemade design will have the required level of quality, and the amount spent on materials will not be very high. All work on the manufacture of entrance doors is divided into several simple stages.

Necessary materials, tools

The most expensive thing you will need is metal. All other components and materials will not be too expensive, of course, excluding decorative finishes. If you roughly estimate the amount for all expenses, then you will need no more than 100-150 dollars. At this price it is impossible to purchase even dubious Chinese products.

As for the materials needed for work, there are few of them. Need to purchase profile pipe– suitable with a cross-section of 20×40 mm. The pipe should be purchased in quantities of 20 linear meters– this volume is quite enough to produce a block of standard sizes (about 1 m wide and 2 m long). It is not difficult to calculate the amount of material for other dimensions. In case of any incomprehensible situations, it is worth looking at the sketch - today you can find a lot of drawings of metal doors and use them for assembly.

Sheet metal is also required. Its thickness must be at least 2.5 mm. dimensions- to the size of the future door, or rather the opening.

You should also prepare the hinges; you should choose models that are equipped with a bearing. These components are purchased in quantities of three. The canvas will be quite heavy, so three loops are the most reliable option.

In addition, additional fittings, thermal insulation, and materials for decorative finishing are required. Don't forget about Consumables– these are circles for power tools, welding electrodes, drills, consumables for jigsaws.

The tools you should prepare are a welding machine, a welding table, an angle grinder, electric drill, jigsaw.

Preparation and measurements

So, standard size the doorway in most apartments is 2000x800 or 2000x900 mm. If the existing opening is smaller or larger, then the canvas can be made to a special size. When taking measurements, you should make sure that it is the wall that is being measured, and not concrete or plaster.

If the height of the box is slightly more than 2000 mm, then it is necessary to provide an additional frame on top, or in the side of the opening if its width is more than 900 mm. In addition, you should remember about a gap of several tens of millimeters on each side of the box. This gap is necessary for blowing in seams.

If the opening width is more than 1500 mm, then experts recommend making a collapsible box rather than a solid one. In cottages, wide openings are installed in addition to door leaf two or more modules with glass, which make the structure more reliable and durable and perform a decorative function.

Click to open in full size.

During the preparation process, it is also worth starting to develop a drawing of a metal door. If the door leaf is unique and exclusive, then the drawing is made with your own hands. If the opening is standard, but door design will represent a standard solution, then standard drawings can also be used.

Making a classic metal door

Classic steel doors- This is a structure made of canvas, frames, door hinges, and mounting plates.

Door frame assembly

So, the first thing you need to do is assemble the box or block. To do this, a prepared profile pipe is cut according to the parameters obtained during measurements. The cutting is done at an angle of 45 degrees. The cutting accuracy can be checked by connecting two pieces, and then checking the resulting structure with a corner.

There is another way to produce a box. In this version, the frame is assembled from metal profile welding method. The result should be a rectangular structure. During the assembly process, it is very important to control the accuracy of the angles, as well as measure the diagonals - this is done to eliminate the risk of block distortions.

Assembling the door frame

At this step, blanks for the future frame are made. A metal corner is suitable for these purposes. It is necessary to maintain a gap between the door frame and the frame on the lock side - it is approximately 5 mm. On other sides it will be enough if the gap is 3 mm. These are not exact numbers - in different drawings of metal doors this size may be slightly different. To make it more clear, strips of metal of the required thickness are used to measure and control these gaps.

Next, the profile is marked and cut. It is placed inside the resulting box. Then the geometric characteristics of the structure are checked along the diagonals. If everything is correct, then a groove or slot is made on one side of the profile for mounting the lock. After this, the corners of the frame can be tacked by welding; the frames around the perimeter are also tacked at several points.

At this step, you can already weld strips of metal to the door frame, which will serve as fasteners for finishing materials.

Manufacturing of door leaf

Creating a canvas should begin with markings. It is worth taking into account the tolerances and overlaps of sheet metal on door frame 10-15 cm each. The overlap from the hinges is also taken into account. In various drawings of metal doors it is 5 mm.

The steel sheet according to the drawings and dimensions is cut using a grinder and welded to the finished frame. Stiffening ribs are welded inside the canvas. They must be installed horizontally. If the level of rigidity is insufficient, then their number can be increased.

Lock installation

The door is almost finished. To install the lock, make markings directly on the canvas. You can mark the holes for the holes with a regular marker. Then a hole is drilled along the marked marks, which then needs to be processed with a file. Next, holes are made for the fastening elements of the future lock. The holes are tapped, then locking device fixed with bolts. At the end, install a handle.

This is a standard instruction that is suitable for most locks, but lock designs may vary, and the installation itself depends on the product.

Loops

Before welding these elements to the resulting structure - doors and block, it is necessary to lubricate them. Using a grinder, the places where the frame and the door block are connected are cut - these are the points that were previously tacked with a welding machine. The hinges are fixed from the inside.

Fasteners

To fasten the resulting structure into the opening, strips of metal are used. You need from 6 to 10 pieces. They are simply welded to the box. Then you will need to drill holes in them for the anchor bolts.

Insulation and finishing

The door is almost ready. Now all that remains is to insulate it. The thermal insulation option you choose is cut and placed inside the canvas. The insulation is placed between the stiffening ribs.

After this you can start practicing decorative finishing the inside of the door. Plywood, laminated panels, and any other material are suitable for these purposes.

Metal door with glazing and decorative elements

Often, such door models are installed in private homes or cottages. The window performs several functions - through it you can see who has arrived. Also, thanks to the glass, the hallway will be much brighter. Decorative elements decorate the canvas and give it an exclusive appearance.

The window in the door must be made while the sheet steel is being cut. When making it, you can use the drawing of a metal door located at the beginning of our article. It is necessary to weld reinforcement along the perimeter of a rectangular or any other shaped hole in a steel sheet. The sizes should be determined in advance. All other stages of work are similar to the technology for manufacturing a classic door.

After the structure is painted, a double-glazed window is installed in the place intended for the window. To make the glass as reliable as possible, a forged decorative grille is often welded on the outside.

You can also equip the door block with various additional accessories. These can be closers, seals, eyes and much more. The main rule is that the fittings must be of high quality. Only then will it last for a long period of time.

Homemade door compared to a factory one

The first disadvantage is the rationality of this decision. The cost of materials and fittings is a considerable amount, although the simplest factory door will cost 30% more, but you will save a lot of time and effort. Also, your welding skills are important. If you are not sufficiently qualified, there is a risk of marriage. In any case, factory welding will be much better.

But generally speaking, homemade door made of metal - this is not a utopia, but a real reality for those who have welding skills and experience working with power tools.

The installation of iron doors is carried out both in apartments of residential buildings, and in bathhouses, garages, outbuildings, private houses, providing reliable protection property from thieves and other criminals.

If purchasing a high-quality metal door is not possible due to the high cost of materials, or due to the need to manufacture a door of a certain size, then self-production iron doors, you can be sure that the design will be reliable, and the costs of the materials used will not be too high.

Planning and sketch

First you need to take careful measurements of the doorway, and also make sure that your walls are made of brick or concrete, and not plywood under a thick layer of plaster. After this, you should display the dimensions of the doors, the installation height of the hinges and lock, stiffeners and other features of the product on paper.

Because metal door blocks installed at the entrance to the apartment, the door leaf should open from the inside out. As prescribed fire safety the entrance door should not create obstacles for evacuation if necessary.

The quality of installation depends on whether you correctly prepare the doorway before installing metal doors. It is important to adjust its dimensions to the dimensions of the door - the more accurately this is done, the smaller the gap between the opening and the door, the more securely the door will be installed. This can be explained by the length of the protruding part of the anchor bolt. If the opening is too wide, then the door is installed in a suspended state - parts of the frame will not adhere to the walls.

Work is carried out on metal workbench. First, we will assemble the box, for which we will cut a metal corner and a profile at 45 ° according to the markings. Then you should check the cutting accuracy, for this you need to connect the frame and attach a carpenter's corner. You can assemble a frame from pipes by welding them in the shape of a rectangle.

During the work, it is important to check the accuracy of the connection of corners and diagonals so that the structure does not become distorted. Weld seams should be processed using an angle grinder so that the blade fits tightly to the door frame.
We make blanks for the frame from a metal corner using pre-prepared rectangles certain thickness as templates. The gap between the frame and the door frame will be about 5 millimeters on the lock side and about 3 millimeters on the other 3 sides. You should mark and cut it, then put it in the door frame, and then check the diagonal.

A slot for a lock is required in the side profile. Weld the frame corners and frames in several places around the entire perimeter. Now you can weld metal strips onto the frame that will secure the door trim.
It is necessary to weld the first stiffening rib inside the door leaf - measure the length of the frame, cut off the profile of the required dimensions and weld it vertically in the center. Then you should clean the weld seams with a grinder.
After all this, you need to mark the canvas. We recommend keeping the overlap of the steel sheet on the box within 10-15 millimeters, and on the side of the hinges – 5 millimeters. Cut the steel sheets with a grinder and weld them to the frame.

Stiffening ribs located horizontally should be welded inside the canvas. If they are not enough, then the volume of reinforcement should be increased.
To install the lock, make markings on the canvas with a marker or chalk. Drill a hole for the lock and file it. Drill the holes required to attach the lock, cut the threads and secure the lock with bolts. Install the lock handle.

To install a lock on a door, other steps may be required (it all depends on the type of product). Read the article about.
Lubricate the hinges and weld them to the door frame and door frame. You should use a grinder to cut the junction of the frame and the leaf, open the door and fix the hinges from the inside using a welding machine.

You can also make a hole for a peephole in the door either through the central profile and metal, or by moving the peephole to the side and then drilling a hole only in the metal sheet.
To make fasteners for the door, take 6-10 strips of metal and weld them to the door frame.

We will then make the holes needed for the anchors in these strips.
To insulate the door, cut a piece of polystyrene foam, mineral wool or other insulation and fill it with the entire area located between the stiffeners.

To make interior decorative cladding, we recommend taking a sheet of plywood that has been pre-cut to size and fastening it with rivets. For finishing, you can use plastic, laminated panels or lining (if you install the door in a bathhouse).

If after production you still have suspicions that the door was not insulated reliably, we recommend reading.
All is ready. All that remains is to coat the door with auto primer and then paint it.

If you wish, instead of painting, you can cover the door with leather or leatherette. If necessary, seals should be installed on the door frame. Drill holes in the welded steel strips, secure the door frame with anchors in the opening, use a level to prevent the door from skewing.

Decorating a door with a window and a figured grille

An entrance door with double-glazed windows is installed in private houses. Due to the fact that light penetrates the window, the hallway will be better illuminated, and forged elements will give the front entrance a respectable look.
