Do-it-yourself rollers for lifting gates. Do-it-yourself lifting garage doors

The convenience of a garage for a car is not least determined by its entrance gate, which should ensure the safety of the car and close easily and securely. Nowadays, you can order or make your own several options for automatic designs. Next, we will consider how to make a do-it-yourself lifting gate for a garage.

Peculiarities

Unlike hinged structures, which in most cases have 2 wings that open outward, lifting gates have sections or roller shutters that rise upwards. Their principle of operation is different depending on the type - sectional, rotary or roller shutter. The structure itself, including various elements: box, guides, rollers, lifting mechanism, much more complex than simple swing gate.

But the cost of installation and materials fully compensate for the reliability and convenience with regular use of such a garage.

Having a ready-made garage with a rectangular entrance opening, you can easily build a lifting gate with your own hands. For installation, you will need a standard set of construction tools, materials for sashes, rails and housing. It is enough to arm yourself with patience and turn on a little ingenuity so that in just a few days, slowly, build a reliable and convenient design of such garage doors.

Advantages and disadvantages

Before deciding to build Garage Doors with a lifting mechanism, you need to weigh all their pros and cons.

Experienced craftsmen note the following advantages such systems:

• Space saving. Unlike swing gates, which need outside space for open doors, lift gates use space inside under the ceiling.
• It is much more convenient to use them, especially if they are equipped with a lifting mechanism, then no physical effort is required at all.
• lifting and turning sectional doors reliably protect the garage from burglary.

• For such structures, one can use different types finishes and decor.
• Lift gates can be used for single and double garages.
• The doors open and close silently.

It is worth paying attention to the disadvantages of lifting gates:

• The main disadvantage is the complexity of design and installation. If you completely order the installation to specialists, then it will be expensive. If you do the installation yourself, then you need to carefully study the drawings, fasten all the elements carefully, under the level, because even a small error can lead to the fact that the entire mechanism will be inoperative.

• Fully open gates take up free space on top of the opening and inside the garage under the ceiling.
• The mechanisms of such gates are designed for a certain load, so the leaves and the body cannot be overloaded, for example, when insulating.
• Lifting gates are installed only in a rectangular garage opening.

If the owner of the garage has taken into account all these features, then you can proceed with the installation. But first you need to decide on the type of lifting gate for the garage.

Kinds

The most common 3 types of home-made lifting structures:

• lift-and-turn or shield:
• sectional;
• roller shutter.

Up-and-over garage doors are the most burglary-resistant due to the one-piece leaf design. When opened, it rises, turning 90 degrees and taking a horizontal position. Their mechanism can be lever-articulated or counterweighted. The first type on the levers is the simplest design that ensures smooth and unhindered movement of the sash to a horizontal position.

Counterweighted gates are most suitable for gates with heavy weights.

Lift-and-turn structures consist of a frame (usually metal), guides along which the frame moves, a spring mechanism or a counterweight with a winch. Lifting can be manual using the handle on the bottom of the case. This is done easily thanks to the extended springs of the built-in mechanism. You can improve this mechanism by connecting an electric drive, then raising and lowering the sash occurs by simply pressing a button.

The leaf of overhead sectional doors is assembled from several panels up to 50 cm wide, which are interconnected by hinged hinges. When it is raised, these panels (they are also called lamellas) move along the guides on rollers. The movement is provided by a spring mechanism, drums and cables. This design is reminiscent of sandwich panels used in construction.

The mechanism of roller shutter doors for a garage is the same as that of roller shutter doors in shopping centers. Their folding slats are narrower than those of the lifting-sectional types; when opened, they rise and twist into a special box of small width. Therefore, this type has a clear advantage - saving space inside the garage. In this case, there is no need to mount long rails under the ceiling.

The materials for the frame, frame and guide rails of overhead gates are usually metal, but stainless steel is the best choice. The box can be made of thick wooden beams or metal corners. One-piece sashes of a similar design can be made in the form of a sheet of boards in a metal frame. Outside they are often sheathed sheet metal.

To keep warm in the garage in winter, heat-insulating materials can be sewn inside: foam sheet or mineral wool.

The box is covered with an anti-corrosion primer, after which it is painted in 2 layers with alkyd or waterproof enamel. The hinged shield is best covered with galvanized steel or aluminum.

Lamellas on sectional or roller doors are usually also made of galvanized steel or aluminum, inside the sheets you can place thermal insulation material. The surface of such panels can be with any color - to the taste of the owner. Movable structural elements - rollers, couplings, are made of plastic or light metals, guides - of stainless steel or other materials that are not subject to corrosion.

Automation of electrically opened doors will greatly simplify the use of the garage. Many drivers don't want to mess around with heavy doors, especially when it's freezing or pouring rain outside. For any design and mechanism, it is possible to choose an electric motor of the appropriate power, which will use current from the household power supply.

There are several types of automatic lifting gates.

The most common schemes that are easy to do yourself are:

• mechanisms installed on the door leaf;
• fixed on guides;
• mounted on side racks.

It is possible to order finished structure, which will already include an automatic drive for lifting, such, for example, are equipped with many roller shutters with galvanized steel lamellas.

In this case, after the purchase, you only need to properly install them on the garage opening and connect the electric drive to the network.

Manufacturing

For the manufacture of simple lifting garage doors, you can use ready-made sketches and calculations, only slightly adjusting their dimensions in accordance with your premises. There are many examples of solutions for country house containing drawings and a detailed report including necessary tools and materials.

Before you make the structure itself with a movable mechanism, you need to make sure that the opening, adjacent walls and ceiling are able to withstand its weight. To do this, you need to choose strong and dense floors without voids and reliable fastening systems. And the room itself must be protected from the penetration of moisture and other natural factors that can damage the operation of the gate.

Having chosen the appropriate type and an approximate project for future sliding gates, we make a drawing with exact dimensions, based on them, we calculate the amount of materials needed.

For a strong and durable frame of lifting garage doors, metal profiles 40x20 mm in size and at least 2 mm thick are most suitable. Transverse and horizontal fastenings for the structure can be made from 20x20 mm profiles. Gate guides are most often made from channels up to 20 cm wide, depending on it, the size of the rollers is also chosen.

The box of the lever-hinge mechanism can be made of metal corner or a bar. According to the dimensions on the created drawing, parts of the desired length are cut.

The rollers themselves, the springs and the entire lever-hinge mechanism are usually bought ready-made. They are selected in accordance with the dimensions of the guides. The rest of the parts can be easily made by yourself using a welding machine and a grinder.

For the manufacture of gates and their installation in the garage opening, you will need the following tools:

• welding machine;
• grinder with cutting circles for metal;
• drill with drills of the required diameter;
• screwdriver;
• hammer;
• level;
• tape measure, pencil.

For fastening, metal anchors or dowel-screws suitable for the given weight of the structure must be used. If you plan to use anchor bolts for fixing a metal corner, then you need to prepare a set of appropriate wrenches.

Mounting

Before you mount the lifting gate system yourself, you need to make sure that the opening on which they are installed has a perfectly flat surface: a strictly vertical and horizontal level, right angles. The carrier box is the most important power element of such gates, so you need to be as careful as possible in its manufacture.

If a metal corner is chosen for the box, then the width of its shelf should be 1.5 times the thickness of the sash. After all the parts are measured and cut, they are attached to the garage opening with anchor bolts and tightened securely. For the manufacture of the box, you can also choose wooden bars with a section size of 100x50 mm, which must be fixed to 100 mm self-tapping screws.

The integral frame of the hinged gate must be assembled on a flat, horizontal surface. After the metal profiles are cut to the desired length, they are checked with a square and lightly tack welded. Next, the right angles and dimensions are checked again, including diagonally, corner scarves and transverse stiffeners are attached, then the structure is completely welded.

After welding the frame, it must be cleaned with a grinder at the joints from burrs. Then it is coated with an anti-corrosion solution and painted. Boards with thermal insulation are sewn inside the metal profiles, outside it is covered with sheet metal. Brackets with movable rollers are attached to the upper corners of the frame.

After that, guides for the future sash are attached to the ceiling. They should also be mounted as evenly as possible, rechecking the horizontal level, parallelism and perpendicularity of the doorway. Then the sash is temporarily installed in the opening in order to mark the place of attachment of the lever-spring mechanism.

After the operation of the gate and the smooth movement of the leaf along the guides are checked, it is removed, the springs are mounted, and they are adjusted. Lastly, a rubber sealant is attached to the frame around the perimeter to seal the seams and soft close, a door lock and an opening handle are installed.

With careful and proper installation, as well as reliable protection against moisture, gates with a similar design can last for decades. And their repair can be limited only to lubricating the moving parts of the mechanism, the lever system, support rollers and replacing the rubber seal. For prevention, lubrication can be carried out every season, and the outer rubber gasket can be lubricated with silicone before the onset of cold weather to protect against freezing.

For internal thermal insulation of such gates, you can use various materials, which are also used for wall insulation: mineral wool, polystyrene foam or polystyrene foam. The last two are more effective, since they do not shrink over time, but they can be fire hazardous, so it is better to choose non-combustible types.

Up-and-over gates have become especially popular today. More and more people choose them. They will reliably protect the room from burglary and at the same time do not take up much space.

Design features

Previously, all gates were the same, with large heavy metal doors painted in unpleasant colors. To date, they have changed dramatically in terms of constructive solution, materials and appearance. To keep your vehicle safe and secure, choose a garage with a secure swing gate. What sets them apart from other models is their unusual design. These gates are the most convenient and reliable type of garage construction, which is quite expensive.

When installing a gate of this type, it is necessary to observe several conditions necessary for further high-quality operation. First of all, this is the size of the opening. The width should be no more than 5 meters, and the height should not be less than 2.85 m. The distance from the wall to the edge of the opening for installing rails should be at least 120 mm, from the ceiling to the upper edge of the opening 210 mm.

Given the dimensions of the vehicle, the dimensions are adjusted.

The design is quite simple. The gate rotates around its own axis, moving from a vertical to a horizontal position and vice versa. Their constituent element is a frame that is fixed in the opening of the room or behind it and is the most important element for opening the gate. It is made in most cases from pipes with a rectangular cross section.

When opening, the roller mechanism and lifting levers are activated, which move the gate leaf along the guides and fix it under the ceiling of the room. The bottom rises up, thus creating a visor. During the closing of the gate, the compensating springs are immediately stretched, and when they are open, they are in their normal state.

It is known that automatic designs can be made to order. But, despite the difficulties in manufacturing, they can be designed by yourself.

The difficulty in manufacturing depends in most cases on the model you choose, the dimensions and your skills in working with drawings, electrical tools and welding equipment.

When making a product drawing, it is necessary to indicate the main points on it:

• wall size;
• opening parameters;
• the size of the main racks;
• junctions of corners;
• length of rails and rails.

If necessary, you can use ready-made sketches of these models by selecting the required drawing. Before starting work be sure to familiarize yourself with the basic principle of operation, as well as the specifics of the installation of this design.

Kinds

According to state standards and norms, this design is presented in three forms:

• Lifting section design, consisting not of a single canvas, but of several sections that are attached to each other by loops. There are usually three loops - along the edges and in the middle. On the sides of the gate there are guides with recesses in which the rollers are installed. When opening, the sections move along the grooves in the guides, one after another rise up. When such gates are opened, the upper panel is displaced relative to the previous one, and an arc is formed. Such gates have good thermal insulation, reduce the distance to the garage, but have a complex and expensive design. Mainly used in industrial areas.

• Lift-and-turn design the most optimal and convenient to use, despite its cost. When opened, it lies horizontally and protrudes slightly outwards. It is easy to use and install. It's pretty hard to crack it.

• Lifting-vertical design commonly used in industrial premises with high ceilings.

How to do it yourself?

If you decide to make an up-and-over gate yourself, then you need to take measurements and sketch a drawing, prepare the necessary auxiliary tools and materials for this, namely:

• return springs;
• brackets;
• counterweights;
• cable;

• roulette;
• level;
• drill;
• components for the manufacture of the sash;
• welding machine;

• corner;
• screwdrivers;
• profile pipe;
• channel;
• guide skids;
• finishing metal, etc.

Materials necessary for the manufacture of up-and-over doors with your own hands:

• a bar made of wood with a section of 100x100 and 120x80 mm;
• 2 springs with an inner diameter of 30 mm;
• corners 40x40 and 4 mm thick;
• anchor bolts and screws;
• steel bar with a diameter of 8 mm.

Before installing the structure, it is necessary to take into account some nuances. Sometimes the installation of the product is not possible, since it is attached only to rectangular openings. The height of the opening decreases when the gate is open. If the sash of the structure is sheathed with a solid canvas, it is dismantled, changing the whole upholstery.

The main components of the design:

• the frame, which is the main element, all other parts are attached to it;
• swing-type sash, which is mounted in a steel frame;
• spring required for manual closing;
• the mechanism that makes the shutters work.

Mounting

The mechanism that makes the sashes work is best made from light weight materials, which will reduce the load on the product, thereby prolonging its long-term use. Next, the mechanism that is used to open the sash is selected. The articulated lever is the most common because of its simplicity and reliability. You can also choose a mechanism on counterweights. It is used in the construction of overall heavy gates.

The following installation steps include:

• Assembly of a box of three bars fastened together with corners or metal plates. The bars are deepened into the floor by at least 2 cm.
• Hinges are installed. At the top, under the roof, a top bracket is installed.
• Sashes are made by cutting metal corners to the required length. Of these, with welding machine make a frame into which the sash elements are mounted and everything is fixed with screws.

• Installation of rails - parts of the product, inside which hinged rollers are inserted. They should move easily and normally.
• To fix the lifting mechanism, the sashes are pre-mounted.
• Fastening the hinge mechanism to the sash. For this, hinges are baited. The levers must move freely and be parallel to each other.
• Connection of counterweights and springs mounted on a guide bracket. The springs must be fixed to the left and right of the sash in parallel.
• Overlays are installed at the ends of the product.
• Plaster joints.
• Mount the lock. You can also control the process of opening the gate using the remote control.

Plastic or metal sheets can be used as a surface finish.

When installing the product, you must:

• measure and make a frame;
• measure the diagonal of the entire opening;
• elements of the canvas frame must be grabbed with a welding machine so that the sash passes easily and the gaps are minimal;
• weld the lintels and all frames with the apparatus;
• put jumpers;

Among various designs gates installed in the garage, the leaf of the lifting gates leaving under the ceiling is especially convenient. This robust design, completely unwieldy, in the open state only the lower end of the gate is visible at the upper edge of the opening. Everything is good, but expensive, to make it cheaper, they make garage doors (lifting) with their own hands.

In this case, we get the same qualities as the factory models: strength, burglary protection, thermal protection and ease of use. That is, all requirements for the design of garage doors are met, but without the high cost characteristic of industrial products.

There are two types of overhead garage doors.

1. Overhead sectional doors have a composite leaf, from a number of panels, about half a meter high. When the gate opens, such a canvas is “pulled” under the ceiling and then falls back down vertically. The panels themselves can be wooden, plastic or made of steel.

The inner space of the door leaf is filled with polyurethane foam insulation, which provides effective thermal insulation gate.

In such gates, the panels are connected using articulated hinges. In them, couplings, rollers and other moving parts are made of plastic or steel, guide rails are made of corrosion-resistant materials. The advantages of this design of lifting gates are simplicity and safety of operation and good strength. The disadvantage is the low resistance to burglary, and it is almost impossible to make such gates on your own.

Here you have only one opportunity to save money: buy a kit ready for assembly, and install the overhead sectional door yourself.

2. An up-and-over gate is a design in which the entire sash rises to the ceiling when opened. The sash movement is provided by a hinged-lever mechanism. Such gates, due to their high strength, perfectly protect the garage from intruders.

Another important plus is the noiselessness of operation when the web moves, since rollers and guides are not used in the design. But the most important thing: it is quite possible to make a swing-up gate for your garage yourself, without the need for narrow technical knowledge and spend much less money.

Choosing an economical option for lifting gates

When it comes to overhead sectional doors complex design, then the only way to save money without compromising the design is to do the installation of the finished complete set gate mechanism. Any other option involves a "sacrifice":

• If you leave the manual drive and abandon the mechanical drive, you can reduce costs by 4 thousand rubles, but lose the convenience of operation;
• You can reduce the size of the opening by adjusting the height and width to the minimum number of panels;

You can “put under the knife” beauty: do not use colored or panels with decorations, but take a monochromatic coloring from inexpensive material which will reduce the cost by 10 percent. From 14 to 18 thousand savings will ensure the rejection of the door in the gate and another 4 thousand less you can pay if you do not take panels with glazing.

There are many more opportunities to reduce costs if a swing-up door type is chosen. Since such a design, in its complexity, is quite feasible on its own. There are the least costs, if you do everything yourself, then the costs will be only for materials. If the owner does not decide to do the lifting garage doors with his own hands, then he can only save on installation if he mounts the finished structure he bought himself. Then the budget for the gate will be equal to the cost of the kit, will be from 40,000 to 60,000 rubles.

Lift-and-turn gate device

Lift-and-turn gates are a structure of three elements: a frame, a lifting sash and a mechanism that opens it. frame made of steel or wooden beams, is the basis of the structure, which is mounted in the opening. IN door frame profiles are installed, which are guides, garage doors move along them when lifting and lowering under the influence of the opening mechanism.

At swing gates door leaf integral, such a design has a much better (compared to a leaf of sections) protection against destruction or burglary and is a significant advantage of this type of gate. The shield can be made from different materials: wood panel, sandwich panel, a shield made of boards covered with a sheet of metal.

The option of a solid wooden leaf has a rather poor cost-benefit ratio for such a gate design. Solid wood itself is an expensive pleasure, but at the same time, it is a heavy material and the canvas will weigh a lot, and the wooden canvas is also vulnerable to climatic factors.

The experience of "gate builders" says that the best option is a plank fabric treated with special compounds that protect against moisture and increase resistance to temperature extremes and mechanical stress. The plank board from above is upholstered with sheet galvanized iron and painted.

To make it warmer in the garage, the door leaf can be pasted over with pressed foam, insulated with polystyrene foam or other heat insulators. And to make the gate more beautiful, they can be lined with plastic or wooden panels.

Lifting garage doors - do-it-yourself

If you want complete freedom in the design of the gate, ease of opening and determining functionality, then the most affordable way in terms of finances is to make and put homemade gates in the garage opening. But first you need to decide which opening mechanism to use:

The hinged lever mechanism is very popular. It is reliable and simple design, which guarantees a simple movement of the sash and is protected from blocking the shield. However, such a mechanism needs accuracy when installing guide profiles and carefully adjusting the spring tension. Be sure to prevent the shield from jamming, you need to set the guides strictly in a vertical position and certainly both in parallel.

The counterweight mechanism is a design in which the cable is attached to the corners of the frame at the bottom, passed through the block and goes to the winch pulley, and at the end there is a counterweight. The greater the weight of the gate shield, the greater should be the mass of the counterweight. With this design, the frame and the gate frame are subjected to a large load. Usually this mechanism is used in the case of heavy, massive gates.

Next, you need to design future gates, take dimensions from the opening and make a sketch (or pick up something from ready-made drawings). When the project and drawings are ready, you need to buy materials and prepare a tool. You will need:

• Wooden bars, for the box - with a section of 12 by 8 cm and ceiling - 10 by 10 cm;
• Metal pins;
• Corner for rails, section 40 x 40 x 4 mm and for the frame -3.5x3.5x0.4 cm;
• Channel bracket 8 x 4.3 x 0.5 centimeters;
• Spring, 3 cm diameter;
• Metal rod 8 mm in diameter (needed for a voltage regulator).
• Now you can start making garage doors:

We assemble a box from two vertical and one transverse bars, we connect the bars with steel plates or squares. The bottom of the box must be buried two centimeters into the floor screed.

We fix the box in the opening with steel pins.

We assemble the frame of the gate leaf and sheathe it with a shield, cover it with sheet iron from the outside;

From the corner we make a support for the mechanism, in one of the shelves we drill one hole for fastening to the racks, and in the other shelf there are 3 holes for attaching the spring bracket. It is better to make a support for the spring from a channel bracket. To fix it, you need to drill 3 holes in one of the shelves.

We make an adjusting plate from an iron strip, with which we connect the spring and the bracket. At the spring, the extreme turns must be bent in the form of hooks, at the bottom, attach a voltage regulator made of a bar.

We make a hinged corner for the bottom from a corner, drill an 8.5 mm hole and weld it to the frame so as to step back from the bottom rib to the middle of the hole. This is necessary to mount the lift arm on a 12cm swivel. Next, you need to attach a plate under the voltage regulator to the end of the lever by welding.

From two corners we make rails for moving the gate. To do this, we compose and weld two corners along one edge, controlling the distance inside between the tops of the corners, it should be 5 centimeters.

Now the rail should be welded to the plate with holes, an 8 cm gap should be left between the lower edge of the cross member and the axis of the guide. To the other end of the rail, weld a piece of channel, with an indent of 12 - 15 centimeters. Next, the channel must be bolted to the ceiling bar.

When installing the gate, it is important to carefully check the horizontalness of the rails. Additionally, the canvas can be improved with locking systems, special security devices and burglary protection mechanisms.

To increase the amount of light in the garage, inserts of translucent material can be installed in the canvas. It will also be useful to stick rubber edging and compensating pads, which together will additionally give stability to the structure, as well as provide the gate stop with protection against corrosion or oxidation.

So, you have seen for yourself that it is quite possible to build a Garage gate (lifting) with your own hands, albeit difficult. This is a serious design, and for the whole mechanism to work properly, precision in the manufacture of parts and care in the installation of the entire structure are necessary. But you will make yourself an excellent lifting gate in your garage and save a tangible amount.

Today, lifting garage doors are very popular, and they are also convenient, reliable and practical protection for the garage, but at the same time, factory options are quite expensive. Opening with the help of a special mechanism, they take a horizontal position under the ceiling and move forward for a short length, thereby forming a small shelter in the form of a visor. As already mentioned, factory samples are quite expensive, but no one bothers to study the Internet resources for self-manufacturing such gates, and armed with the necessary tools and drawings, make them with your own hands.

Advantages and disadvantages of the lifting structure

The lifting structure perfectly fulfills the function assigned to it and has a number of undeniable advantages over other types of garage doors, but at the same time it is not without drawbacks.

Advantages:

• No additional opening space required. The unused space under the ceiling is used.
• The one-piece construction of the canvas provides reliable protection against penetration.
• Any exterior finish and decoration can be used.
• The door leaf can be additionally insulated with expanded polystyrene.
• It is possible to supply equipment for automatic opening.
• Can be used in both single and double garages.

The disadvantages are primarily due to the design features lifting mechanism and the inability to do otherwise.

Disadvantages:

• Installation is only possible in rectangular openings.
• In case of damage, a single piece of cloth must be replaced, since it does not imply partial repair.
• When the gate is open, the height of the opening decreases.
• The door mechanism is designed for a certain load and this should be taken into account when insulating.
• Some complexity of installation.

The device and scheme of operation of folding garage doors

The system of lifting (shield) gates is a fairly simple mechanical device. The main and load-bearing elements are the frame, the guides and the lever-spring mechanism that moves the sash. The mechanism can be controlled both manually and using an electric drive controlled by a remote control (remote control). When opening the gate, levers attached to the lower part of the sash, and two guides for the movement of the rollers, fixed at the top of the sash, are used. Opening is carried out by lifting the lower part of the sash by the handle and is done quite easily, since the stretched springs of the lever mechanism help in opening the gate.

There are two types of lift gates:

1. Lever-spring - a fairly simple and reliable mechanism, which is popular among garage owners. Mounting features: Precise adjustment of the tension springs and high quality and precision mounting of the roller guides.
2. With counterweights - mainly used on gates with a large leaf weight. The cable is attached to the lower corners of the sash and passes through the pulley to a counterweight attached to the other end of the winch.

Lifting garage door drawing

When preparing a drawing for your opening dimensions, you should already use ready-made solutions slightly adjusted them to their sizes. Here is an example of drawings for the manufacture of gates:

Frame drawing, dimensions must be put down for your gate dimensions.

What is required for the manufacture

For the manufacture of the sash frame, profile pipes of rectangular section with dimensions of 40 * 20 and a wall thickness of 2 mm are most suitable. For transverse and longitudinal spars we also use profile pipes, but smaller sizes - namely 20 * 20 * 2 mm, to reduce the weight of the structure. For sewing up the front and inner sides of the sash, a profile sheet is best suited, since it is already initially covered with an anti-corrosion compound from the factory. You can also use sheets of galvanized sheet.

For guides, it is ideal to use a channel up to 20 cm wide. The size of the channel shelf depends on the width of the rollers used in your particular case. The box to which the lever-spring mechanism is attached in the garage doorway can be made of wooden beam 100*50 mm. For these purposes, you can also use a metal corner with a shelf of 50 mm.

Roller rollers and lever-spring are bought separately in a store specializing in sliding gates.

For thermal insulation of the gate, for reasons of price and quality, it is advisable to use expanded polystyrene with a thickness of 40 mm and a density of 15 to 25 kg / m 3.

Instruments

For work, the following tools should be at hand:

• Bulgarian;
• welding machine;
• tape measure, pencil;
• hammer;
• screwdriver, screwdriver;
• drill, drill;
• set of wrenches;
• level.

Step by step manufacturing instructions

1. The box installed in the opening is the main power element of the gate. It is the main load of the entire garage door system. The box is made of a wooden beam 100 * 50 mm or a thick metal corner. The width of the corner shelf should be 1.5 times wider than the thickness of the sash, that is, if the thickness of the sash is 40 mm, then we take the corner with shelves of at least 60 mm. The details of the box are installed with the letter P, two on the sides of the opening, one on top. If we use wood, then we fasten it with 100 mm self-tapping screws into pre-prepared wooden mortgages. In the case of using a corner, we make fasteners on anchor bolts, however, they are perfect for the first case.
2. Let's start assembling the frame for the gate leaf. profile pipe cut to size according to your drawing. We lay out the frame elements on a flat horizontal surface and, after checking the right angles with a square, we grab the joints. Before fully welding the joints, it is necessary to check the length of the frame diagonals with a piece of cord or a tape measure. If necessary, you can correct the product and proceed to the full welding of the joints. We weld scarves at the corners of the frame, as shown in the drawing, to enhance the rigidity of the structure.

We clean the welds from burrs and the entire frame from rust with a grinder.

3. We cover the frame with an anti-corrosion primer and paint with alkyd enamel in 2 layers with intermediate drying.
4. We weld to the upper corners at the end, brackets with rollers.
5. We put it on the frame and fasten the profile sheet with self-tapping screws with a drill and a rubber washer in increments of 15–20 cm. We fasten the sash opening handle to the M8-M10 bolts. This operation can be done at the end of the installation work, which significantly reduces physical exercise on workers when checking the operation of mechanisms.
6. On the ceiling we fix the guides for the rollers. We check their parallelism and perpendicularity to the opening.
7. Temporarily install the sash in the opening to mark the attachment point of the lever-spring mechanism. We remove the sash and fasten the levers along the marks to its ends with self-tapping screws.
8. We install the sash and check the operation of the gate. If everything is in order - the gate opens and closes easily, then remove the sash and fasten the levers to the bolted connections.
9. Installing and adjusting the springs in place and checking the functionality.
10. Bonding a rubber seal around the perimeter of the frame to seal gaps.
11. Door lock installation.

How and what to insulate

The classic heaters used for these purposes are mineral wool and polystyrene foam boards. Styrofoam compares favorably with mineral slabs in that it does not shrink over time. We will insulate the sash with foam plastic 40 mm thick and density 20. First, we insert the foam plastic without fastening into the sash in order to cut off all the necessary cuts to size. Styrofoam sheets are glued to the profile sheet with inside between the spars on the "liquid nails". Next, we fasten the inner plane of the sash with a sheet of galvanized sheet with self-tapping screws with a drill.
