Installation of sliding gates: from pouring the foundation to installing automation

Installation of sliding gates: from pouring the foundation to installing automation

Sliding or sliding gates are gaining popularity among private developers, since all the necessary components for their installation at an affordable price have appeared on the market. In terms of cost, swing gates are, of course, cheaper. Sliding structures benefit from aesthetics and ease of use. You can reduce costs by saving on the services of installation companies by installing sliding gates with your own hands. This is not so difficult to do if you understand the diagrams, watch video tutorials, and also consult with experienced home craftsmen. To carry out the work, a ready-made kit for the installation of cantilever-type sliding gates is purchased, which includes two rollers, a carrying beam made of a U-shaped profile, several traps and holders. The assembly and installation of the sliding gate structure is carried out in a specific sequence.

This video clearly shows the process of installing a sliding gate with your own hands. After viewing, all previously raised questions about the installation of sliding gates will disappear by themselves. Each individual operation is shown in this way clearly and simply.

Briefly about the device of sliding gates

Below is a diagram and a list of the main elements of a ready-made set of sliding gates presented on the market by both foreign and domestic manufacturers of this type of equipment.

Legend: 1. Guide U-shaped beam; 2. Roller supports or carts (two pieces); 3. Removable end roller; 4. Lower catcher; 5. Top catcher; 6. Upper clamp with rollers (bracket); 7. Plate for fixing roller bearings

On a foundation specially prepared for the installation of sliding gates, a pair of bearing roller supports is fixed at a certain distance from each other. The guide U-shaped beam is welded or screwed to the bottom edge of the metal frame of the door leaf. Roller supports not only withstand the load falling on them from the entire structure, but also ensure its free movement. The supports are fastened using embedded bolts or a special plate that is securely fixed to the foundation.

Fastening of roller supports to a steel channel, laid in the foundation together with the reinforcing cage, is carried out using bolts or welding

The gate is installed on roller trolleys so that they are inside the U-shaped supporting beam. This arrangement protects the rollers from contamination, which affects the duration of their trouble-free operation. As a result, the gate easily rolls to the side, both in manual control mode and automatically with the help of an electric motor.

Important! The frame for the door leaf, welded from a profile pipe with dimensions of 60x40x2 mm (main frame) and 20x20x1.5 mm (lintels), must be sufficiently rigid. After all, the gate leaf is under the influence of wind loads, which can be very significant. The canvas should also not undergo any deformation under the pressure of its own weight.

Many manufacturers are engaged in the production of fittings for sliding gates, among which the most famous on the Russian market are ROLTEK (St. Petersburg), CAME and Rolling-Center (Italy), DOORHAN (Moscow).

The sets of accessories required for the installation of sliding gates are subdivided according to the weight of the structure and the width of the clear opening into three standard sizes:

  • small (up to 400 kg and up to 4 m);
  • medium (up to 600 kg and up to 6 m);
  • large (from 600 kg and from 6 m).

When choosing the required set, they are guided by the width of the overlapping opening, the height of the canvas and the total weight of the entire structure.

Preparatory stage - pouring the foundation

Work on the foundation for the sliding gate begins with the marking of the trench. At the same time, from the edge of the opening on the side of the gate rollback, the length of the concrete base is set aside, equal to half the width of the passage. The width of the foundation is 40-50 cm. When calculating the depth of the pit, the level of soil freezing in a given area is taken into account. In the Moscow region, the foundation is laid with a depth of 1.7 m, and in Siberia - 2.5-3 m.

An embedded element is made from the channel 18 and reinforcement (d 12), connecting all parts by welding to each other in accordance with the diagram. The channel must be used to enhance the strength and rigidity of the base being constructed. The low alloy steel used in the production of channels is able to withstand low temperatures and does not corrode. The length of the channel blank is equal to half the width of the opening. The length of vertical reinforcing bars is calculated on the basis that they must go below the depth of soil freezing.

The embedded frame is welded from a channel 18 and reinforcing bars, the diameter of which is 12 mm. Reinforcement can be replaced with steel corners

By connecting the vertical rods with steel lintels, a strong reinforcing cage is obtained, which is lowered into a prepared trench for pouring the foundation. Previously, a layer of sand is poured onto the bottom of the trench, which is carefully compacted.

Important! The level of the foundation must match the level of the road. The value of the ground clearance must be higher than 5 cm so that there are no problems when operating the door in winter.

Before pouring the foundation, you should check the horizontal position of the reinforcing cage, using a building level for this. During alignment, also make sure that the longitudinal axis of the steel channel is parallel to the fence line.

If you plan to install a drive to automate the control of sliding gates, then at the stage of pouring the foundation, wires are laid, hiding them in special corrugated tubes. The location of the exit of the bundle of wires is selected based on the planned location of the electric drive. Usually the equipment is installed in the middle of the foundation.

A reinforcing cage is lowered into a trench prepared for the foundation. In this case, the plane of the steel channel is aligned with the level of the roadway

To fill the foundation, a concrete solution is kneaded from 4-5 bags of M400 cement, crushed stone (0.3 cubic meters) of sand (0.5 cubic meters). The poured foundation is left alone for 3-5 days, during which the concrete will gain the required strength. After the specified time, they begin to install the sliding gates.

Step-by-step instructions for installation work

Mark the door movement line using a cord stretched along the opening, placing it at a height of 200 mm from the road surface and at a distance of 30 mm from the counter post. Along this cord, you will align the position of the supporting profile (beam).

Prepare roller carriages for installation and insert them in sequence inside the supporting profile beam. Then move the carts towards the center of the gate. Place the gate leaf with the roller supports inserted into the profile on the steel channel of the embedded structure. Then place the first and second supports in the marked places, and adjust the gate so that they are parallel to the stretched cord and touch it.

Fastening roller carriages to the channel

Weld the adjusting pad of the second roller support to the channel. Having rolled out the gate into the opening to the very end and having checked the horizontal position of the curtain, weld the adjusting platform of the first roller support.

  • Remove the sliding gate leaf from the roller supports.
  • Remove the supports themselves from the adjusting platforms.
  • After welding along the contour, weld the adjusting pads to the steel insert.
  • Attach the roller bearings to the welded adjuster pads.
  • Slide the sliding gate curtain onto the roller supports.
  • Place the door in the closed position and adjust the horizontal position of the plane of the supporting profile. To do this, use a wrench to raise or lower the adjusting platforms relative to each other.

Installation of the front bearing roller trolley is carried out 150 mm from the edge of the door opening, so that when they are fully opened, the end roller will abut against the support

Important! It is possible to give the gate a horizontal position only if it is in a closed state.

Freewheel regulation

Adjust the position of the rollers inside the support profile. To do this, slightly loosen the upper nuts securing the roller bearings to the adjusting platforms. Close and open the gate by rolling it from edge to edge several times. In this case, the roller supports will be able to take the correct position inside the bearing profile, in which the gate moves easily and freely. After completing the adjustment of the gate free play, tighten the upper nuts of the roller supports tightly.

Mounting the end roller and plugs

Next, the end roller is installed, as well as the cover of the bearing profile. To do this, an end roller is inserted into the bearing U-shaped profile, placing it on the front side of the door leaf, and the part is fixed with fastening bolts.

The cover of the bearing profile, supplied in the set of sliding gates, is welded on the back of the door leaf. This detail prevents the load-bearing profile from being clogged with snow in winter, which prevents the gate from jamming.

When installing the top bracket, it can be used for fastening both anchor and welding. Bracket rollers are lubricated after installation for better sliding

To install the upper guide bracket, loosen the fasteners of its rollers. Then the bracket is placed over the door leaf in such a way that the rollers touch the upper edge of the door leaf, and the side with the holes provided for fastening is directed towards the support post. Pressing the bracket to the surface of the support post, fix the part with fasteners.

Sheathing of the door leaf with profiled sheet

After that, they proceed to sheathing the door frame with a profiled sheet, cut in height and width to the desired size. The installation of the profiled sheet begins from the front edge of the gate. The cladding is fastened with self-tapping screws or rivets. Each subsequent sheathing sheet is superimposed on the previous sheet by one wave.

The most often used material for covering sliding gates is profiled sheet, which is complemented by forged elements that give the structure an elegant and special look.

Installation of catchers: why and how?

One of the last stages of installing a ready-made set of sliding gates is the installation of catchers. The bottom catcher, installed when the door is fully loaded, allows partially removing the load from the roller supports when the door leaf is closed. To determine the position of the lower catcher, you must close the gate and align it with the end roller.

The upper catcher allows you to keep the door leaf, which is in the closed state, from swaying during the action of sailing loads. The installation of the upper catcher is carried out at the level of the protective corners, and in the closed position they (corners) must touch the brackets of the upper catcher.

Rules for self-installation of automation

At the last stage, the installation of automation is carried out, if this option was originally planned. In this case, the movement of the sliding gate leaf is carried out using toothed racks, which are sold in meter-long pieces together with fasteners. The slats are attached to the supporting profile. When installing automatic sliding gates with your own hands, you should know that in addition to the toothed racks, you will need an electric drive, a remote control, a beacon lamp and a key. Everything is installed in full accordance with the requirements of the instructions attached to the equipment for automatic gate movement control. If in doubt, consult an experienced electrician.

As you can see, you can cope with the installation of sliding gates on your own. However, this process cannot be called easy. Not only knowledge is required, but also physical effort. Therefore, many private developers prefer to entrust the installation of sliding gates to professionals.

How to make sliding (sliding) gates: making console gates - photo report, video

Hinged gates are good for everyone: they are simple and cheap. But in winter, with a lot of snow, they can only be opened thoroughly with a shovel. When you need to go to work, this is not at all happy. Sliding or, as they say, sliding / sliding gates are devoid of this drawback. The one-piece construction, covering the entire entrance, slides to the side, hiding behind a fence. They can be held on a regular or cantilever beam, or they can simply ride on rails. In any case, you can make a sliding gate with your own hands. It's not easy, but possible.

Main features of sliding gates

Sliding gates are a modern and practical design that saves a lot of space required to open them. The peculiarity lies in the fact that the door leaf moves along the fence, taking up a minimum of space. This is the main advantage of sliding gates over swing gates.

Sliding single-leaf gates made of metal profiles

The modern classification involves the division of sliding gates into varieties according to the following criteria:

The degree of automation of opening and closing the gate

According to this parameter, two types of structures are distinguished:

  1. Mechanical
  2. Automatic.

Mechanical sliding gates are the cheapest and easiest option. Opening as well as closing of such structures is carried out only manually.

Automatic sliding gates have much broader functionality than their mechanical counterparts. The person is involved only in pressing the buttons.

Classic single-leaf sliding gates with automatic control

Sliding gate automation

The door leaf moves using an electric drive, which can be started in the following ways:

Start button

The device is switched on by pressing the corresponding button. The disadvantage of this method is that the button is located directly next to the gate.

All electrical devices, including the power button, must be reliably protected from dust and moisture.

Remote control (RC)

This is a much more convenient option than the push-button method. The remote control allows you to open the gate from a distance. However, it should be located directly in front of the receiver. Limit switches are provided to stop the web.

GSM module

It is the most advanced way to control a sliding gate. Distance here does not matter at all, and you can give a command to open or close structures from another country or even a continent. The main thing is that the areas are provided with high-quality mobile GSM-communication.

Gates using GSM technology

The device and design of sliding gates

According to this criterion, sliding sliding gates are divided into three types:

  1. Rail
  2. Suspended
  3. Console.

  • Rail gate - are the easiest option to manufacture. The shield, together with the frame, moves by means of rollers along a special guide rail fixed on the base. This type of structure can be used on various openings, but the most popular is the opening - the minimum width and height of which is 7 m and 2.4 m (respectively).

Doors on rails are not limited in terms of the location of the drive, providing the least load on it. However, the rail of such structures requires additional maintenance, especially in winter.

Rail-type suspension gate device

  • Hanging gates - very similar to their rail counterparts, except that the guide rail is placed in the upper part of the structure, and the shield together with the frame is suspended from it by means of rollers. Thus, such structures set certain restrictions on the height of passing vehicles, which depends on the level of the guide rail.

The drive mechanism is also located at the top, which greatly complicates the work associated with the repair and maintenance of equipment.

Installation of suspended gates is quick and easy

  • Cantilever gates - do not have any restrictions in terms of the opening height. Also, there is no need to equip the foundation along the length of the structure, this is due to the lack of a guide rail.

The big disadvantage of cantilever doors is the need to install a reinforced support pillar, which supports the weight of the entire structure, as well as the presence of additional space for the counterweight and console. The standard console is in demand in openings with a height and width of 2.4 m and 6 m (respectively).

Number of sliding leaves

Two types of sliding gates can be distinguished here:

  1. Single leaf
  2. Bivalve.

The second option, in addition to the additional sash, requires the installation of an additional drive mechanism, which leads to a significant increase in the cost of the structure. That is why the demand for double-leaf sliding gates is less than for single-leaf ones.

Experts do not recommend making single-leaf sliding gates, the opening of which is more than 4 meters

Stage 2 - calculation of sliding gates from corrugated board

For the normal functioning of sliding gates, you need to correctly calculate the parameters of their main elements:

Gate weight

The weight of a sliding gate has a direct effect on all load-bearing elements. The total mass consists of the weight of the frame, the counterweight (shank), the weight of the skin, the weight of the decorative elements. If it is planned to manufacture a gate from a corrugated board with an internal wicket, the weight of the frame and the material of the wicket is taken into account. The weight of locks and automatics, although not so significant, should not be neglected in the calculations either.

It is possible to reduce the weight of the door leaf by arranging two leaves. Those. instead of sliding, make sliding gates.

For example, the weight of a 4-meter gate, welded from a 60x20 pipe, sheathed with corrugated board on one side, is about 200 kg.

Pillars for sliding gates

For support pillars, a large metal pipe is suitable.

Console length (guide rail or beam)

The length is determined by the width of the opening plus ½ the length of the counterweight (shank). It is not recommended to decrease this parameter, because the rollback mechanism will wear out quickly. With a door width of 4,000 mm. the length of the console will be 6,000 mm. Thus, the side of the fence, on which the door leaf will go, must be longer than 6,000 mm.

If the fence is shorter, you should make two gate leaves with two counterweights and automation kits. This increases the cost of sliding gates, but will allow it to "fit" into the given dimensions (the length of the fence next to the gate). Otherwise, you need to install a swing gate made of corrugated board.

A counterweight ¼ of the door width is only possible when using roller guides on the console.

Influence of the weight of sliding gates on the parameters of the guide rail (console)

Gate leaf weight, kg Section of the guide rail, mm. Steel thickness, mm.
Up to 300 60x70 3,5
300-700 85x95 5
800 and more 170x180 12

Section of the beam (rails) for sliding gates


The heavier the gate, the more durable the fittings need to be purchased. This will avoid its deformation and skewing of the door during operation.


The more massive the leaf of the sash, the more powerful you need to take automation. In turn, the automation for sliding gates is selected taking into account the power reserve. Therefore, when buying, you need to add 100 kg to the weight of the gate.
