Very often the customer is interested in the question of the relationship between the size of the gate leaf and the post on which it is attached. Let's try to understand this issue using the example of a gate made of corrugated sheets.
Frame material
The frame of the gate leaf is made of profile metal pipe cross-section 40×20 or 40×25 with a wall thickness of one and a half to two millimeters. Let's calculate the mass of the frame for the sash. To do this you need to know the weight of one meter profile pipe, from which the fabric of the future design will be made. So, 1 meter of 40x20x1.5 pipe weighs 1.4 kilograms, and one meter of 40x20x2 pipe weighs 1.7 kg. For ease of calculation, we provide examples of common gate designs.
Sketches for calculating length and weight
Sheathing material
The material for the cladding in our case will be corrugated sheeting for fences marked C20 with a thickness of 0.5 mm. Square meter This material has a mass of about 5 kilograms. For swing gates 4 meters wide (the most popular size is from 3 to 4 m) with a fence height of 2 meters, 4 sheets are needed, two for each leaf, i.e. it turns out to be a maximum of 20 kilograms.
So, the weight of one gate leaf is about 40 kg. This weight can be supported average person. The weld seam with which the gate is attached via a hinge to the post is capable of withstanding a load much greater than that created by the specified mass. Therefore, two loops for each half are quite enough.
Pole material
The pillars must be used with a wall thickness no less than the wall thickness of the pipe from which the gate frame is made. Of course, the larger the cross-section and thickness of the wall, the stronger the pillar will be - but in every case, for well-known cost reasons, the “golden mean” is the criterion. Therefore, a sufficient solution for swing gates made of corrugated sheets would be a post 60×60×2 or 80×80×3.
Fastening the pillars
It is important how and in what way the pillars will be fixed in the ground. Fundamentally there are two various methods installations: with and without concreting pillars. The first is more expensive and in most cases preferable, although there is a risk of concrete being pushed out. Before making a decision, we advise you to consult the experience of your neighbors - this is the most reliable way to predict the behavior of the soil for your area. The second installation method is cheaper. It has another advantage - repairs, if necessary, are carried out much faster and easier.

Clients from Moscow and the region are provided (if necessary) with turnkey services - delivery of gates, installation (including automation), commissioning, subsequent service and repairs. The cost can be obtained from the manager.
How to calculate dimensions
- The width of the opening - for a private house and cottage, if only passenger cars are planned to pass through, this figure should be at least 3 - 4 meters.
- The length of the rollback zone of the sash with a counterweight = opening width x 1.6.
- The width of the door leaf = the width of the opening + 20 cm. The maximum length of sliding gates is 5 m; for higher values, it is rational to order sliding structures.
- Sash height = 20 cm subtracted from the height of the supporting pillars.
- Foundation depth = 20 cm is added to the soil freezing level.
- Channel length = opening width divided by 2.
With a total weight of the structure up to 300 kg, a guide beam of 70x60x3.5 mm or 70x50x3 mm is selected, from 300 to 700 kg - 90x50x3.5 mm or 95x85x5 mm, more than 700 kg - 180x170x12 mm. When purchasing a support pipe, it is necessary to take into account the weight margin - from 30 to 100%.
How to determine the weight of a standard 4-meter sliding gate
The most popular option for filling the frame is corrugated sheeting. The average weight of the material (depending on the thickness of the sheet) is 4 kg/sq. m. As a result, a sash of standard structures (for an opening 4 m wide and a sash height of 2 m) will weigh on average 336 kg + 130 kg (frame weight) = 466 kg.
The garden plots of private houses are fenced with a fence, in which, regardless, a gate for the passage of people and a gate for a car must be installed. Most often, swing structures are used for these purposes, less often – sliding structures.
Metal is usually used as a material for gates, since metal ones, unlike wooden ones, will last longer.
What should the gate be like?
At self-production or purchasing ready-made gates, you must take into account the basic requirements that they must meet. The gate must be:
- durable and rigid, as well as resistant to burglary and entry into the territory;
- moderately heavy - their weight should withstand gusts of wind, and at the same time light, so that they can be easily opened and closed;
- aesthetic and individual - swing gates can be made more beautiful and elegant than standard and monotonous metal sliding or sectional ones.
Dimensions and weight
The height of swing gates used in the private sector usually does not exceed 3 meters, for industrial structures - 5.5. As the height increases, the mass of the doors and their windage increases, which leads to difficulties in operation.
The width for each case is calculated individually. The main criteria for calculation include:
- availability of free space;
- width of the vehicle that will pass through them: take the maximum width of the car and add a margin so that it can pass freely, for private houses 3 m is enough - width passenger car does not exceed 2 m and 50 cm on each side for free passage.
Making gates large sizes unless absolutely necessary, it is not always practical: firstly, a large area will lead to increased wind load, and secondly, the structure will be heavy, so additional reinforcement will be required.
The weight of metal swing gates depends on what material was used for their production. An approximate calculation is done like this:
- The frame is a profile pipe 40 × 20 mm with a wall width of 2 mm. The weight of 1 m of profile pipe is 1.7 kg. For a gate with a width of 3 m and a height of 2 m from 2 leaves, the perimeter will be 12 m. Each leaf is reinforced with transverse beams - 1.5 m for each. It turns out that you need 15 meters of profile pipe, the total weight of which will be 25.5 kg;
- Sheathing – sheet steel. Thickness metal sheet– 1.5 mm, total weight will be within 70 kg.
It turns out that the weight of metal swing gates will be about 95.5 kg. Add to it the weight of the locking hardware, decorative elements And so on.
Advantages and disadvantages
Swing gates are both excellent protection of the territory from penetration and a simple and convenient design. They have a number of advantages, namely:
- in production you can use modern metal profiles, and this in turn gives scope for bringing design ideas to life;
- Most metal elements are coated with a special polymer coating, which protects against corrosion, temperature changes, etc.;
- There are no visible fastening elements on metal swing gates, so they are more difficult to break into;
- the design can be made according to individual project, using elements of artistic forging, automatic opening and much more.
But, just like any other gate structures, swing gates also have disadvantages. Since the sashes are quite heavy, they may become skewed and lowered. This problem is solved by installing more powerful supports made of brick, reinforced concrete or steel.
If the gate leaves are wide and therefore heavy, it is more difficult to avoid their sagging, as well as wear and bending of the hinges. As the area increases, the windage and, accordingly, the wind load will increase. 
Swing gate designs
There are several types swing structures, each of which performs its own specific functions and also reflects modern look at the gate. Among the most popular are:
- forged - protective decorative functions;
- aluminum – lightness and speed;
- made of corrugated sheets - reliable and comfortable.
Forged swing gates
Aluminum structures used with automatic drive in service parking lots and company territories. They look modern and businesslike. The doors close quickly, easily and almost silently.
The doors are made from aluminum profile 96 × 177 mm or , protected from deformation by an internal diagonal cable stretch. The manufacturer guarantees 25 - 28 thousand operations, and no corrosion for 15 years.
From profiled sheet
The design of metal pipes covered with profile sheets is considered the most popular, modern and practical. Such doors are practically not inferior in strength to forged gates, and the ability to make the structure yourself only increases their popularity.
In the manufacture of this option, the same technology is used as in production. The cladding can be easily matched to the color of the fence. The weight of doors with a height of 3 meters will be about 300 kg. And the cost is much less than aluminum and forged options.
Approximate prices for the above designs:
When choosing a gate for your site, experts recommend being guided by the following principle: if the fence is made of metal profiles or modular sections, for it the best option there will be swing gates made of aluminum or steel profile, and a forged option would be an excellent choice.

- aesthetic and individual - swing gates can be made more beautiful and elegant than standard and monotonous metal sliding or sectional ones.
GOST No. 31174-2003 regulates all the requirements for metal gates, and also describes all their main types. In addition to swing and sliding structures, there are 9 more options - these are sectional, folding, etc. However, all these fencing systems are not often used, since their installation is accompanied by some difficulties: installing a technological arch or a niche for the canvas.

Norms and technical conditions
The requirements for swing gates are defined in GOST 31174-2003, it contains general provisions, but specific characteristics are determined directly during the design. To reliably lock and block the opening, the gates must be installed on massive pillars and have a strong frame.
The strength of the frame is ensured by the presence large quantity metal elements, which entails an increase in the weight of the structure. And this in turn increases the load on the frame and hinges of the system. Therefore, in order to avoid breaking of hinges, as well as sagging of sashes and other emergency situations, the GOST stipulates the condition - mechanisms and components for swing doors metal structures must be manufactured strictly according to project documentation and manufacturer's calculations:
- hinges and canopies, as well as the frame and frame must have a double safety margin, and the quality of technical solutions must be confirmed by certificates of conformity from the standardization center and a sanitary and hygienic conclusion of the State Sanitary and Epidemiological Supervision;
- metal swing gates should not have metal surface defects visible to the naked eye;
- welds must meet strength and continuity standards;
- the difference in height and width of the racks should not be more than 5 mm;
- tolerance diagonally for metal sashes up to 2 m – 3 mm, for sashes over 2 meters – 5 mm;
- The paint coating layer must be at least 30 microns and must not cause allergic reactions upon contact with skin.

The resistance of the structure to shock loads is checked by dropping the assembled sashes onto a hard surface. After all the tests have been carried out, the manufacturer draws up a technical passport of the product and applies markings indicating: model VM (metal gate), GOST number and dimensions.
Dimensions and weight
The height of swing gates used in the private sector usually does not exceed 3 meters, for industrial structures - 5.5. As the height increases, the mass of the doors and their windage increases, which leads to difficulties in operation.

Making large gates without urgent need is not always practical: firstly, a large area will lead to increased wind load, and secondly, the structure will be heavy, so additional reinforcement will be required.
The weight of metal swing gates depends on what material was used for their production. An approximate calculation is done like this:
- The frame is a profile pipe 40 × 20 mm with a wall width of 2 mm. The weight of 1 m of profile pipe is 1.7 kg.

Forged swing gates
They serve not only to protect the passage, but also decorate the territory of a private home. All doors can be forged completely, from the frame to the lintels and small parts- the most expensive, but beautiful models. For cheaper options, the main elements, such as the frame of the doors and lintels, are made of pipes, and artistic forging parts are used as decoration.
The doors of forged structures are most often suspended on hinges from mortgages in brick pillars. The upper part of the doors can be either completely open or with decorative polycarbonate inserts. The bottom part is usually closed metal cladding.
Aluminum
Aluminum structures are used with automatic drives in service parking lots and company areas. They look modern and businesslike. The doors close quickly, easily and almost silently.

Metal swing gates: GOST, weight, dimensions
A fence of any type and design should always have a wicket and entrance gates, most often swing or sliding, allowing passage of a car or even a truck into the site. Today, metal swing gates are most often used for private properties. Less often - light recoil ones. The larger the fenced area, the taller and more serious the building, the more monumental the fence, the higher the gate, the more metal is used to make the frame and supports, ensuring the stability and strength of the structure. It is not surprising that instead of cast iron and welded profiles, modern swing gate structures are increasingly using aluminum and forged rods.
Which gate is better
Today the manufacturer strives to make gates for private properties:
- Maximum strength and rigidity, ensuring the resistance of the protective fence to breaking and entering into private territory;
- Heavy enough so that the weight of the gate and inertia make it possible to withstand wind breakthroughs, and at the same time light so that the installation and operation of swing metal gates does not require the use of huge massive pillars and supports;
- Beautiful and graceful. Old as the world, swing gates can look hundreds of times more attractive than the monotonous and boring design of metal sliding, lifting or sectional entrances.
In reality, for high-quality metal swing gates these values can easily be exceeded by 50-70%.
GOST No. 31174-2003 summarizes and describes all the main types of metal gates. In addition to swing and sliding systems, nine more options can be used to “lock” the passage, from sectional to folding. But in structures for fencing the territory similar devices are used quite rarely, since their use requires the installation of special technological arches and niches for cleaning the door leaf or panels. In rare cases, roller shutter systems can be used to lock and block passages, but in this case, installation will require converting the open gate base into a closed structure with the installation of a technological arch niche or cross beam over the passage.
To open the heaviest metal systems with swing doors without using an electromechanical drive, the effort of just one person is enough, while opening or moving sliding structures without using a standard electric drive is much more difficult.
Standards and technical specifications for swing metal systems
To ensure reliable locking and blocking of passage, metal swing gates have to be installed with a massive frame or pillars, and most importantly - with a large number of steel load-bearing elements that ensure the strength of the main frame. This leads to an increased weight of metal swing gates and a huge load on the frame and hinges, first of all.
To avoid breakage of the suspension, sagging of the sashes or emergency situation in case of strong gusts of wind, GOST establishes the requirement that all mechanisms and components of swing metal structures must be manufactured only according to design documentation and strength calculations of the manufacturer:
The resistance of swing metal structures to shock loads from wind is tested by dropping the folds assembled on the frame under their own weight onto a non-destructible object. Based on the results of the tests, the manufacturer issues a passport and applies markings in accordance with GOST. The encoding indicates the VM model - metal gate, GOST number, product dimensions.
Features of metal gates with swing doors
Each gate design has its drawbacks, and systems with swinging halves also have them. Using the principle of drop-down metal halves is very convenient for small openings of 2-2.5 m.
IN standard version small passages design entrance gate assembled similarly to the device of metal garage doors. In this case, hinges are welded onto steel vertical posts made of channel or I-beam and sashes are hung from sheet metal thickness 3-5 mm. Due to the fact that the structure of the shutters is heavy, and there is no upper horizontal beam, as in metal garage doors, there is a risk of the pillars skewing and the shutters lowering. Rigidity problems can only be solved by installing very powerful support pillars, steel, brick or reinforced concrete.
The wider the passage, the more the gate leaf will weigh, which means it is more difficult to ensure a stable position and the absence of sagging of heavy leaves due to wear and bending of the hinges. In addition, the area of the gate structure increases, which means the windage and horizontal load from gusts of wind increases .
Therefore, for passages more than three meters wide, special structures are used:
Practical swing gate designs
Each of the listed options, in fact, reflects a modern view of the main functions of the gate. Option one - protective and decorative functions characteristic of forged steel structures. The second is a fast-acting and lightweight version of aluminum swing gates, the third is reliable and convenient, inherent in steel gates made of profiled sheets.
Forged swing gates
They are best suited for protecting access to a private property. The forged steel frame of the doors is capable of withstanding the most severe load, significantly exceeding the standard 200 kg, defined by GOST as a base value. In the most expensive beautiful options All parts of the doors are forged, from the outer frame to the internal lintels and decorative details. In cheaper metal versions, the main strength elements, the frame of the sashes and lintels are welded from ordinary pipes; forged parts only complement the appearance.
The forged frames of the shutters are suspended on hinges from the embedded elements of the brick pillars. The lower part is covered with a cladding made of thin sheet metal, the upper part of the doors can be completely open or have decorative inserts made of darkened polycarbonate.
Forged gates are much more difficult to manufacture than conventional frame gates due to the large number of welded parts. To reduce the influence of thermal stresses and achieve a standard two-millimeter gap between the sash and the fixed frame, metal gates They are welded in the form of one sheet, the hinges are welded and hung on poles, and only after that they are cut into two sashes.
Aluminum swing gates
The second style is a modern business style, in which the doors open and close quickly and clearly, as much as possible using modern drive mechanisms. For example, the stopping power of aluminum swing gate leaves is not considered by the manufacturer as the main property; fast and flawless operation of the device is much more important. Most often, aluminum frame swing and sliding structures service parking lots and controlled areas of companies and firms are equipped. In addition to automatic swing panels, the entry mode is controlled by a security guard.
The gate is a classic example of a swing system. The structure is made by argon welding of a profile with a cross-section of 96x177 mm from high-purity aluminum. Each sash is suspended on a concrete pillar using triple hinges with an increased size of the supporting surface. Internal diagonal braces made of cables and a support “patch”, which serves as a support and limiter of movement, help to compensate for possible deformation.
The manufacturer of swing gates claims a device life of 25-28 thousand operations, with a guarantee against corrosion for 15 years. The door leaf is made in the form of a cladding made of aluminum profile or sandwich panels. The cost of the structure greatly depends on the width, for example, a 2000x3500 mm gate of the ADS400 system will cost just over 50 thousand rubles, a 2300x3500 mm door is estimated at 75-77 thousand rubles, and 2300x5000 mm - all 90 thousand rubles.
Steel frame schemes
Frame metal doors made of pipes and profiled sheets can be called the most modern and practical option. Firstly, it is quite possible to assemble such a structure with your own hands. Secondly, the steel frame made of pipes is only slightly inferior in strength forged gates. Thirdly, such metal gate systems will cost much less than aluminum and, especially, forged ones.
The external cladding can be quite simply selected from a huge number of colors of profiled sheets. At the heart of construction frame options The same technology is used as when constructing a fence. The average weight of two leaves of a three-meter gate will not exceed 300 kg.
Conclusion
When choosing the sizes of swing metal gate structures, experts recommend being guided by the principle of sufficiency and expediency. For an area fenced with a metal profile fence or modular sections, a metal swing scheme made of aluminum or steel profile is perfect. For a stone fence best choice There will definitely be a forged scheme. Thus, the style and durability of the gate will correspond to the material and structure of the fence.

The sliding type of gate is quite reliable, but installing it is quite a responsible undertaking, because even the slightest mistakes can lead to big problems. It is better to entrust the calculation of the necessary parameters to professionals. However, this is not at all a prerequisite - anyone can independently calculate sliding gates.
This is a rather difficult moment, but everything will be much easier if you know the basic parameters that need to be taken into account. First of all, attention should be paid to the following:
- width;
- height;
- length;
- components and materials.
If you know the values of all these indicators, you can calculate the sliding gates yourself. At the same time, if one of the many additional parameters is unknown, it is better to play it safe. To do this, it is enough to take the necessary components with a reserve.
Materials for sliding gates
Before starting work, it is necessary to carry out all the required calculations. Not least in the case of this is the calculation of construction materials.
The following details depend on it:
- total weight of the structure;
- selection of components;
- installation process;
- windage;
- dimensions and weight of the counterweight.
In most cases, either corrugated sheeting or steel 2 mm thick is used. The weight of these materials is noticeably different. In the first case it is 4 kg/sq.m., in the second – 17 kg/sq.m. Accordingly, all further calculations will differ. When choosing, you should choose those that are designed to weigh one and a half times the weight general design, which will ensure ease of operation and durability.
Width and requirements for it
This indicator of sliding gates depends on such a parameter as the width of the opening. For example, if the gate is designed for an opening of 4 meters, then a leaf 4 m long + 200 mm will be required. It is they who will ultimately cover the gaps on both sides. It is also necessary to add 200 mm in the case of other sizes.
Accordingly, the optimal width of sliding gates should not differ much from the width of the opening, which they are supposed to cover.
The foundation is an important part of sliding gates
The foundation deserves special attention. For example, the foundation for a sliding gate 4 meters long must withstand the load not only of the structure, but also the possible influence of other factors. One of them will be additional load from wind or other conditions.
The cost of the foundation often reaches 30-40% of the entire work estimate, but it will largely ensure the stability of the structure.
Required size of rollers and pipes
Installation similar products a rather labor-intensive process with the need to calculate many indicators. One of them is the size of the pipes for sliding gates. Using the example of a gate with a leaf width of 4 meters and a height of 2 meters, a pipe of 60*70 mm for the main frame and 40*20 mm for internal fastening. This will be enough to withstand the loads of a large gate, however, as the size and weight increase, it is necessary to increase the size of the pipes.
Another important indicator is the size of the rollers for sliding gates. In the situation presented above, you can use both polymer and metal rollers with a guide with a length of 6 meters and a applied cross-section of 60*70 mm. Since the weight of such a structure, covered with corrugated board, will be less than 400 kg, such a set will be sufficient to perform the functions.
Beams and product height
The dimensions of the sliding gate beam depend on the length of the gate. To this indicator it is necessary to add 1.5 lengths of the product. This size will be enough to carry out all necessary actions automation and for structural stability. When choosing all the details of a sliding gate, you must focus, first of all, on the dimensions of the opening. It is this indicator that will subsequently influence many parameters and the final result of the work.
When choosing sliding gates, the height of the finished product is also of particular importance. Usually this is approximately 2-2.5 m. This is quite enough to complete the task - protection from the outside world. Greater height will only bring additional weight and increase the sailing effect, which in turn will create additional stress on the remaining parts of the structure. The height of sliding gates from the ground depends on several factors.
Among them it is worth highlighting the following:
- dimensions of component parts;
- terrain features;
- correct installation of all parts.
The main thing is to take into account every nuance, even the smallest one - an error of a few centimeters can lead to incorrect operation of the entire mechanism.
Length and weight of different designs, counterweight
There is one simple way to calculate the optimal length of a product. Based on it, the length of sliding gates should be calculated as follows: gate length + 200 mm + 1.6 opening lengths - this is exactly the manufacturer’s recommendation. This will be needed to create a sufficient counterweight.
The weight of the finished structure deserves special attention. The weight of a 6-meter sliding gate usually fluctuates around 600 kg. It all depends on the materials used for cladding. At the same time, the weight of a 5 meter sliding gate will be approximately 500-550 kg. Accordingly, all required parts should be calculated to weigh at least 600-650 kg. The minimum weight of a 4 meter sliding gate will be 300-400 kg. In this case, the weight will not have any special differences.
Should I buy it with installation or do it myself?
If you have some knowledge, you can make sliding gates with your own hands from scrap materials. Everything you need for this can be found at your nearest hardware store, and many structural elements can even be at home. It is enough to know what material is needed for sliding gates and a little skill, after which the result will not be long in coming. However, it is better to entrust the entire process to specialists.
