We install roller shutters ourselves. Rolling garage doors: correct installation Do-it-yourself rolling garage doors

There are many different designs of gates: sectional, swing, lifting. Electric roller gates or roller shutters are ideal for a garage and closing the yard from prying eyes.

Peculiarities

Rolling gates, also known as roller gates or roller gates, are a unique locking design that allows you to close a room without any joints. The canvas in this design is rolled into a roll, which is where the name of this type of shutters comes from. They are very convenient to use in small areas, since they do not require a separate space for the diameter of the plow.

Advantages of rolling gates:

1. Roller shutters perfectly cover a room or yard due to the complete absence of any seams or cracks;
2. They look beautiful. As a rule, steel options or PVC sheets can be painted in any color, they can have texture or other decorations;
3. They are durable. Hörmann Decotherm classic and Rollmatic models can last up to 50 years;
4. Provides quick opening and closing of doors. High-speed gates are very popular among car enthusiasts.

Flaws:

1. They are not as easy to develop independently as swing or sliding ones. To create them, you need not only to carefully consider the design, but also to accurately calculate the tire and the height of the blade;
2. They are characterized by high heat transfer. If conventional lifting or rotating ones can be insulated using mineral wool or foam plastic, rolls are not insulated;
3. Despite their external reliability, plastic shutters are susceptible to hacking. They are not loaded and are not protected from external influences by resistance ribs. Because of this, with a strong impact they can easily be broken;
4. Fireproof built-in roll-up Garage Doors For a fence or room, approximately 5–7 centimeters of usable space are taken away.

Design

The gate is divided into two parts: visible and invisible. The visible one is lamellas or canvas; it is divided into several sections. Such blinds are wrapped in a protective box, and the closing process is controlled by an electric drive. It refers to the invisible part of the gate.

Automatic or high-speed roller garage doors can be made from:

1. Hollow slats. They are made of PVC, steel or other materials. They are canvases with internal stiffeners;
2. Viewing sheets. This profile has perforations that retain air. They consist of two panels, inside of which there are stiffening ribs and space for air. Can be either plastic or aluminum;
3. Profile. These steel roller shutters are a strengthened version of the perforated ones. They are made from two sheets, each half a millimeter thick. Between in separate parts The panels are equipped with stiffening ribs, which ensure the strength of the panels.

Also structurally, entrance roller gates can be mechanical (which open and close with your own hands) and automatic. Each control scheme has its own advantages and disadvantages. With manual control there is no dependence on electricity or drive operation, but at the same time, automation is more convenient in everyday use.

But at the same time, internal structure the system is practically the same regardless of the type of control. Sectional roller shutters are screwed onto a prismatic shaft. The width of the sides of the prism depends on the size of the lamellas. The shaft is mounted on cantilever rails or carriages. To protect the blades from wear, a special design is installed in which the shaft moves slightly to the side during unwinding.

Installation

Industrial and domestic roller gates can be installed in the following ways:

1. Ceiling;
2. Built-in;
3. Wall-mounted.

Let's look at how installation is done using all the options.

1. The invoice is the simplest and fastest. Our instructions involve the installation of ready-made systems (for example, from Hormann or Alutech - Alutech). A prismatic shaft is installed on one of the walls;
2. Guides are mounted on both sides of the prism, along which the metal sectional doors will move;
3. Rollers are installed on top of the guides;
4. The web is wound onto the shaft required size(the width must correspond to the size of the doorway). The dimensions of the lattice may be slightly larger than the dimensions of the garage or fence, but in no case can they be smaller;
5. It should be noted that if a gate design with a wicket is used, then it is necessary to install an additional beam between the door and the wall with the shaft. Then the width of the canvas is measured to this beam;
6. After winding, the shaft is connected to a lever or drive.

This is how street roller gates with a wicket are most often installed; insulated options for a summer house or garage are installed on the ceiling. At the same time, it should be noted that built-in ones are mounted using the same technology, but with grooved walls and installation of the shaft inside the opening.

For installation on the ceiling, special components will be required: consoles and pendants. Here the installation is not fundamentally different from the overhead method:

1. A prismatic shaft is mounted on the ceiling, and guides are lowered from it on both sides (respectively, along both walls);
2. Rollers are attached to them, and the shaft is additionally strengthened with pendants or cantilever beams. After this, you can begin winding the shutters;
3. After completing the installation of the sectional grille, the shaft is connected to the lever or drive.

Price overview

Let's look at where you can buy economical roller gates from Doorhan (Dorkhan) with a size of 3000x2500, and what their price is in different cities:

If the sale is made directly from the manufacturer (from a warehouse), then the price of the gate will be an order of magnitude lower. Repair of rolling gates is often carried out by specialists, since if one panel breaks, at least two adjacent panels will need to be replaced.

Roller garage doors are perfect for buildings where the room itself is not large and there is not enough space on the outside for other door options. Today we will look at roller garage doors and everything connected with them.

This ranges from characteristics to installation rules. Installing a roller garage door is not that difficult; you just need to follow the instructions for doing the work.

Advantages of roller garage doors

Rolling garage doors have their advantages, but they are not suitable for everyone. Let's take a closer look at them. The popularity of this type of design is not accidental, since reviews of such a product are only positive.

• Durability;
• Ease of operation;
• Minimal heat loss (subject to proper insulation of the fabric);
• Good noise insulation;
• Strength.

Good strength characteristics are achieved through the use of several sheets of steel and polyurethane foam, which is located between them. The latter plays the role of insulation.

Attention: The thicker the section, the higher the price for garage doors of this type.

• The panels have a polymer seal that, even at low temperatures, retains its elasticity and tight fit to the surface, which ensures complete tightness and prevents cold from penetrating inside. Galvanized steel tape protects the panels themselves from external negative factors.
• It is necessary to talk separately about the panels, or more precisely about their outer covering. They are applied polymer coating, preventing scratches. They do not crack in frost or sun, and are also resistant to chemicals. This makes the panels durable - they will last fifteen years or even more. All handles, hinges and hooks are made of materials that have the best anti-corrosion properties. This makes it possible to install rolling gates even in cities with high level humidity.

Manufacturers pay special attention to safety indicators:

• The design of the panels and connections completely eliminates pinching of fingers.
• Limiting the effort prevents people from lifting when opening the gate.
• To compensate for the weight of the canvas, a spring mechanism is used.
• If there is a power outage, it is possible to switch to manual mode.

Installation of roller gates

Rolling garage doors are produced in various configurations. Here you need to proceed from the structural features.

Their price mainly depends on the size of the canvas. They contain the following mechanisms and components:

• Control device;
• Protective box;
• Guide bars;
• Barrier cloth.

When lowering or raising the barrier cloth, it begins to move using special side guides under the influence of traction force, which is created by the built-in electric drive control.

• Unlike other structures of the same type, roller gates are assembled only from high-quality components industrial production. If some improvised materials are used when assembling them (sometimes they are used in sliding gates and swing type), then this may cause undesirable consequences, namely, breakdown or failure of the main components.
• In this case, it is best to purchase ready-made roller gate kits, which can be installed on your own without any problems.
• If you decide to assemble it yourself, it is important to carefully follow the instructions that come with the kit.
• A wide selection of colors, as well as the attractive appearance of the assembly materials included in the kit, allows the design to fit into a building with any architectural style.
• Rolling gates have a working opening width of up to five meters; the gates themselves can be installed not only outside garage, but also inside the premises itself.
• It is worth noting that the second option (i.e. internal installation) significantly increases the reliability of protection against intrusion into premises by intruders.
• This type of gate operates under the control of an automatic drive system and is operated manually (this is achieved using an emergency lift system). As a rule, the option of installing gates is chosen in the case when the installation of swing gates and recoil type(see) cannot be performed.

Installation work

If you have weighed the pros and cons, and have decided on rolling gates, then you can begin installing them. It should be noted that in order to achieve best result, it is best to entrust all work to workers who are professionals in this matter.

It is simply impossible to make such gates with your own hands. The maximum that can be discussed is their self installation, but this process will require a person to have certain skills, tools and abilities, and they may be missing.

But if you want to save money or control the actions of workers, then knowing the main stages of installation is simply necessary.

Preparation

Gate installation, like all other work, must begin with proper preparation:

• Here we are talking about getting rid of all the finishing and interior elements that will interfere with the work process.
• The shaft together with the door leaf must be installed in the upper part of the door opening. Therefore some part ceiling decoration, if present, will need to be disassembled.

Attention: It is important to inspect the opening, because guide elements will be installed along which the gate strips will move and hold.

Installing guides

The next stage of installing rolling gates is to install the guides. Such elements are strips into which the edges of the canvas are installed.

There they are held with the help of a special fastening system. These design details are installed on inner surface side opening.

Shaft mounting

Then, when working with roller shutters, there comes the moment of direct installation of the shaft on which the leaf is secured. The entire system will be set in motion by him.

• This shaft is installed in tandem with the box.
• Not only a shaft is placed inside, but also a gear system and a chain drive, without which the entire system will not function.
• As a rule, the shaft is treated with a special compound that prevents the formation of corrosion. It is equipped with a pair of ball bearings that rotate it.

Attention: It is worth noting that depending on personal preferences, as well as design features the box can be installed inside the opening or on the inside, outside. The door leaf itself is attached to the shaft.

Installing the drive

The last stage of work is this procedure.

• The drive starts the entire system. It can be equipped with an electric motor or be manual.
• The second option is much cheaper, but the first is much more practical, because control can be carried out using a remote control.
• Among other things, it is important to understand that rolling gates can have additional protection against unwanted entry by thieves in the form of an alarm, as well as additional locks (see).

Attention: It is important to equip the electric drive with additional protection against moisture and dust.

• In conclusion, all this should be added that installing a garage door will be enough interesting option, which has a lot of positive aspects.
• But we should not forget that for security purposes, the entrance to the territory itself must be equipped additional locks, because such a gate is, after all, a rather mediocre defense. Otherwise, this option is worth paying attention to.

Rolling garage doors are not that difficult to install. If you look at the photos and videos, then you will understand everything immediately.

Here it is important to take your time and make the correct markings. Then the system will work for a long time and will not cause you any trouble.

There are many types of garage doors, each of which has a lot of positive and negative aspects. We are already accustomed to traditional swing doors, which have a simple and reliable design. However, in some cases their use is not entirely justified. It is more profitable to use alternative options. Today we will look at roller garage doors, including economy class ones, their design, components, operating principle, as well as the features of do-it-yourself installation.

Roller gates in the garage

What are roller gates?

Roller shutter gates are a leaf consisting of many profile aluminum or steel elements called lamellas. Their thickness is usually 19-23 mm, and their width is 37-120 mm. The lamellas have voids inside, which are filled at the factory with polyurethane foam insulation. The slats are connected to each other by means of a hook-lock, forming a flexible sash. All spaces between the lamellas are lined with insulators. An end piece is attached to the bottom of the leaf, ensuring a tight fit of the sash to the floor during the closing process.

In addition to the main leaf, roller garage doors consist of the following structural elements:

• The shaft on which the fabric is wound.
• Mechanical lifting device.
• Box for placing the canvas.
• Mechanical control device.
• Drive with an electric motor that raises and lowers the flexible sash. In some versions, the motor may be missing. The drive is then controlled manually.
• Guides located on the sides of the gate. They are U-shaped aluminum profiles with a wall thickness of 2-3 mm.
• Rollers, brackets and fasteners.

Advantages of roller barriers

• This is an economical option. Space saving around the garage is achieved.
• Lifting roller shutter structures can be installed in garages where it is impossible to install other types of entrance systems. For example, in ground floor or if there is not enough space near the garage.
• Versatility. Can be used in openings of any size.
• Quick opening and closing of the flexible sash. Using electric drive You don’t even have to make any physical effort.
• You can install economical lifting gates with your own hands, as they have a simple design. Of course, you need to skillfully handle tools and understand technology.
• The porous insulation located inside the lamellas provides sufficient heat and sound insulation of the garage space.

Disadvantages of roller shutter structures

• High cost for large canvas sizes.
• Low resistance to vandalism.
• Inability to equip a gate for entry. Every time you have to lift the main canvas to enter the garage. If it is necessary to make a gate, then it is made separately from the roller shutter structure.

Operating principle of roller shutters

The flexible sash opens only at the operator’s command. You can control the sash using a button located inside the garage, or use a radio control unit for this purpose. During the opening process, the sash rises and is wound onto a rotating shaft. So it is fixed by a special mechanism. The sash is closed in the reverse order. Conventional window shutters function in exactly the same way. The movement of the sash is assisted by rollers, which ensure smooth movement of the leaf.

The sash is controlled manually, or by electric drive. In the latter case, the system is additionally equipped with an emergency lift in case of a power outage. Roller doors must also be equipped with an emergency brake in case of possible failures. A special gearbox should prevent the sash from falling quickly.

Installation of roller gates

Let's look at how to install roller gates on a garage with your own hands. In most cases, the guides and the box with the canvas are installed with inside garage. This ensures higher reliability of the design. External method Do-it-yourself installations are chosen if the thickness of the box with the canvas does not allow it to be placed under the garage ceiling.

Roller doors for garages can be installed overhead or built-in. The overhead method involves placing the box on the wall. With the built-in method, the box is located at the bottom of the upper garage slope.

The work is performed in the following order:

1. The opening and the space under the ceiling are cleared of all unnecessary things, such as electrical wiring, communications, etc. If there are any irregularities, they must be eliminated. Irregularities of no more than 5 mm per linear meter are allowed.
2. Preparing guides for installation. 2 walls are drilled with your own hands according to the marks for attaching the guides.
3. The box is being prepared. You need to remove the front cover from it, and then drill into back cover holes for mounting the box on the wall, and for entering the electrical cable.
4. The guides are mounted in the grooves of the side covers.
5. The box is connected with your own hands to the guides.
6. The finished frame is measured by applying it to the opening.
7. If the dimensions of the frame correspond to the size of the opening, then the frame is rigidly fixed in place.
8. The main sheet is fastened, after which it is leveled strictly according to the level.
9. Taking into account the position of the section in closed, install vertical guides with your own hands.
10. A drive is installed that will drive the roller shutter gate.
11. Electrical wiring is connected if an electric drive is selected.
12. The operation and smooth movement of the sash is checked. If there are jams in any place, you can try to lubricate the rollers.

We looked at what roller garage doors are. If installation is carried out correctly, the operation of such a structure will be established within a few hours after the start of installation. If handled with care, such a system can last for decades without causing any trouble to its owner. To ensure the security of the garage, it is recommended to equip the roller structure with additional locks.

Garage doors (rolling doors) are similar to regular roller shutters. The blade is made of AG77 profile, the thickness of which is 14 mm and the width is 77 mm. Such parameters allow you to close the opening of a large garage without compromising strength.

Description of the gate

Roller garage doors have low thermal insulation properties. But the design has the following advantages:

• low price;
• compactness;
• installation in a limited area.

Experts advise installing roller gates on a garage by first preparing a metal base. It should be located inside the opening, outside or indoors. High-strength slats provide resistance to burglary.

Rolling garage doors can be equipped with automation, which is controlled by a remote control or keys on a stationary remote control. If necessary, an emergency door opening can be installed. This will allow you to lift the structure manually if there is no electricity. If the garage is small, you can control the canvas using a cardan.

Garage doors - roller shutters are installed if a gate is not installed. There are other reasons for choosing of this type canvases:

• there is no possibility (due to the opening) to install another gate;
• the need to quickly open the garage.

Before installing metal roller shutters in your garage, you need to study the operating principle of the future structure. During the process of opening the gate, the slats are wound onto a shaft installed in the box. During the reverse process, the shaft unwinds the slats, closing the garage opening. The door leaf consists of vertical guides, a door leaf and a shaft. To install roller garage doors, you will need special components.

Preparing for upcoming work

To install the structure in question, you will need a tape measure, wire cutters, a hammer, a screwdriver, a drill, a hammer drill, a knife, and a level. If the garage opening is made of brick, gas block, you will need to buy metal corner. If the preparation is done efficiently, then the installation will be with minimal costs. The opening must be level.

To install a garage door yourself, it is recommended to purchase durable guides. At the same time, a set of components is checked:

• 2 guides;
• box;
• prefabricated fabric made of lamellas;
• electric drive with box.

Open roller garage doors, unlike traditional ones, do not protrude onto the roadway, interfering with maneuvers. The canvas does not require space near the wall or under the ceiling of the room. This design is made to order and is easy to install yourself.

Rolling garage doors are made from durable material and easy to use

The main part of the gate is a leaf consisting of narrow profiles secured together with a longitudinal hook-lock. At the bottom of the canvas there is an end piece that ensures a tight fit to the floor. There is a reinforced part at the top that ensures fixation to the shaft. The lamellas are made of aluminum by roller rolling or they are extruded from the melt.

Using the latest technology, hollow lamellas with internal stiffeners are produced. If the garage is not heated, you can install roller shutters with viewing or ventilated blinds. The first design has small windows that provide natural light to the room. The second design has narrow slots to prevent moisture penetration.

The strongest fabric is considered to be a structure assembled from lamellas 0.5 mm thick. But if you take into account corrosion resistance, then it is recommended to give preference to aluminum lamellas. Any roll sheet makes a lot of noise during the opening and closing process. The maximum maximum width of a structure made of aluminum panels is 4 m.

Box elements

The shaft, casing, tires and transmission must be from the same manufacturer. Otherwise, the roller garage door cannot be assembled. The shaft looks like an octagonal prism. It rotates on 2 bearings and can be installed movably or permanently.

Any design has emergency shaft braking. This system eliminates the possibility of abrupt closing of the gate if the gearbox breaks down. The shaft can be left open or covered with a casing. The door leaf has a locking system that helps the gate cope with wind loads.

Seals are inserted into the tire grooves to protect the assembly from dirt and dust. At the same time, silent movement of the gate is ensured. The choice of guide assortment depends on the installation method. The manual mechanism does not provide modern level comfort. This drive is used if there is no electricity in the garage.

Roller garage door mechanisms

More often, roller shutters are equipped with a cord or spring-inertial mechanism. Such systems provide that the weight of the structure will not exceed 80 kg. The first system is a gearbox with a handle, which is fixed to the wall at a height of 1 m. It is then connected to a pulley using a cable.

The second system consists of several extension springs that are mounted on guides. They compensate for the weight of the canvas. If the value of this indicator exceeds 80 kg, then a mechanism is mounted with a powerful spring installed in the shaft. For an emergency, a crank mechanism is installed.

Control system

Rolling gates are equipped with an inexpensive and practical electric drive in a housing that fits into the shaft. The system operates from the network. Engine power does not exceed 500 W. If the canvas has big sizes, the axial drive is mounted. It is fixed to the wall near the box. It is connected to the shaft using a coupling or chain drive.

Electric motors are characterized by different noise levels, rotation speeds, and types of switches. If such engines overheat, they turn off for 10 minutes. If it’s frosty outside, then cheap units will function intermittently. In such cases, the canvas will not rise.

Modern drives are equipped with thermal fuses. They prevent short circuits and distortion of the entire structure. If there is an end profile and some kind of obstacle, and the shaft continues to work, then the web unwinds and the structural parts are damaged. Experts advise installing a system with a “smart” unit. It regulates the maximum torque.

The system can be equipped with a hollow rubber tube and sensor. Such a device will stop the drive even if it touches an obstacle lightly. To pre-detect an obstacle, photocells are used. They are mounted in the opening or in front of it.

To give a command to the block, the remote control is used. He can be modern device, equipped with small sensors operating at a distance of 50 m. One unit can have an unlimited number of remote controls. The backup control is installed from the inside on the fence or wall of the garage. A switch with code buttons or a key is mounted outside. You can use the remote control to control roller garage doors and all roller doors installed on your summer cottage.

Mounting options

Experts advise installing roll sheets in 3 ways:

1. invoice;
2. lintel;
3. embedding into the wall.

All methods differ in results and labor intensity. The first method is the simplest. In this case, the shaft is attached above the opening to the wall, and guides are mounted on the sides. Outdoor installation used if the room is equipped with roller shutters that maintain the integrity of the facade pattern.

Installation of rolling gates is possible in several ways

Internal mounting is considered more universal method. It does not require application additional elements. At the same time, the details of the canvas are protected from precipitation. With the lintel method, the shaft is attached at the top of the opening. The box does not protrude beyond the walls.

If necessary, it is hidden under the covering material. This installation method is used if the height of the canvas exceeds 2,400 mm. Installing a structure into a wall is a labor-intensive method that is rarely used, since the box has large cross-sectional parameters.

To apply this method, you need to think about this even at the stage of building a garage. A niche for the box is built above the opening, then it is sealed with brick and covered with clapboard. During the lowering process, the blade comes out easily.

Installation of the structure

To install a roller shutter, you need to install pillars on one foundation. They are not deepened much, but only well reinforced. The racks are connected on top with a lintel or steel beam. A roof is installed over the canvas to protect it from precipitation. To automate the design, an axial or intrashaft drive is installed.

Installation of the canvas begins with assembly U-shaped frame. The work is done on the floor. The upper part of the frame is equipped with a box with a shaft, and the side parts are equipped with tires. The finished portal is attached to the walls of the garage. Then the web is wound onto the shaft.

When conducting installation work the resistance of the structure to wind loads is taken into account. This parameter is considered important, so it is taken into account when assembling the roller shutter. If the system is equipped with a drive, then a gate lock is not required. The drive allows you to lift the blade 7 cm from the ground.

To increase resistance to burglary, you can install a lock or profile with bolts and a cylinder. If a gate with springs and without an electric drive is installed, then a lock must be installed.

How will the drive work if there is no electricity? In this case, the drive blocks the shaft and the gate does not open. The power unit or transmission may fail. To open the leaf equipped with springs, an emergency release is used. It is controlled from the inside using a rod and from the outside using keys.

Such a system is presented in the form of a neutral gear that disconnects the motor from the shaft and lifts the blade by hand. Gates without springs are equipped with an electric drive with the ability to rotate the gate. In this case, it is provided indoor installation boxes The gate can only be opened manually from the garage side. For such structures, you will need to build doors or a gate connecting the garage to the house. Another way is to install a loop under the knob.

Conclusion on the topic

Taking into account the location of the box, the slats face the street with a convex or concave surface. For coloring aluminum profiles are used polymer compositions, resistant to moisture, mechanical damage, and ultraviolet radiation. The surface of the lamellas can be embossed or smooth.

If light profiles are used, then the canvas will weigh 4.7 kg. If the structure is equipped with extruded profiles, the gate weight reaches 7 kg or more. Rarely does the weight of a roller shutter gate exceed 80 kg. But a falling structure can injure a person or damage vehicle. Therefore, the system in question must be equipped with a braking mechanism.

Profiles for construction are rollformed and extruded. Roller shutter models open and close slowly. However, such cycles cannot be repeated several times in a row. Roller gates are used only for exit and entry of vehicles.

It is recommended to supplement a remote control system equipped with a drive that detects an obstacle with a cord release. It will allow you to quickly open the structure manually if the lights are turned off or the drive is broken. The decision to automate is made at the gate design stage.

Experts advise giving preference to a motor that has a reserve torque. An exception is a drive with an obstacle detection function, which must correspond to the weight of the structure. Practice shows that in 8 out of 10 cases the control unit breaks down, and only in 2 cases does the power unit or gearbox break down, so experts recommend installing external unit control with sensitive edge of roller shutter gates.

Recently, roller gates, or, as they are also called, roller shutters, have become increasingly used for the arrangement of garages. In some cases, they are also installed at the entrance to the site. The vertical method of opening this type of structure saves as much internal and external space as possible compared to other types of doors.

How the system works

The quality of operation of the gate depends on the correctly selected elements for it, so the components must be from the same manufacturer. An exception may be drive and automation.

Installation of roller gates:

Canvas made of roller shutter profiles– lamellas connected to each other by longitudinal hooks.

Guides– 2 vertical tires, the width of which depends on the thickness of the canvas elements, and the length on the height of the opening and installation method.

During operation of the gate, lamellas fall into the U-shaped profiles, which are held there by special fastening locks. To protect the mechanism from debris and dirt, special brushes or seals made of polymer materials tubular shape.

Receiving shaft– the leaf of the sash is wound around it when opening. It is an octagonal prism driven by two ball bearings installed at the edges. Made from high-strength, sometimes galvanized, steel.

The shaft can be in one position or change it, moving closer to the opening while opening or closing the gate. The second option ensures smoother sliding of the lamellas, which immediately fall into the groove and do not experience additional loads.

Box– necessary to protect the roll from external factors, can be square or semicircular in shape.

Drive unit– distinguish between mechanical (for manual opening) and automatic. They are selected with a power reserve in case of external natural influences. The exception is drives with an obstacle recognition system; they can take care of themselves, but require strict compliance with the weight of the web. Heavy roller shutters require a more powerful drive.

Drives are also divided into:

• intra-shaft - usually built into the structure and inaccessible without its dismantling;
• axial - remote, mounted on the wall near the box and connected to the shaft with a coupling or chain type connection.

Locks– depending on the drive, a deadbolt (key operated) or automatic type of locking device is installed.

Roller gates have size restrictions:

• width – from 150 to 430 cm;
• height – from 150 to 270 cm;
• by weight of the sash - from 4.7 to 80 kg, heavier options are practically not found.

The design has enough simple mechanism actions. When opened, the canvas, consisting of lamellas, is rolled into a roll, which is hidden in a special box. It can be located both inside and outside the box.

Control automatic system available in several options:

• a button that is installed in the wall near the sash;
• remotely - from a remote control or a special key fob, range of action - 50 m;
• using an intelligent system whose sensors react to light, temperature or other changes.

Manual drive - opening with a key, often used as a backup in case the electricity is cut off. Although, with a budget option for small-sized structures, it can be the main one. For such cases, there is a limit on the weight of the canvas - no more than 30 kg.

Features and advantages of the design

Distinctive feature designs - vertical opening method. This provides a lot of advantages compared to other types of devices: there is enough room for maneuver in front of the box - about 2 m, the box does not reduce the height of the entire room.

Roller shutter sheets are good noise reflectors and weather protectors when installed internal insulation in lamellas, can reduce heat loss by 20%. Have a nice appearance, unlimited color design And design ideas. Garage shutters can imitate rare types of wood or stone, supporting façade features private home or landscape.

The design is easy to operate and does not require special care - just wipe with a damp cloth. Saves money on Maintenance: No need to paint or frequently lubricate. If one lamella fails, it is easy to replace. Garage doors budget option They have a service life of about 10 years, and the price is a little more than 7 thousand rubles.

Disadvantages of roller shutter structures

Despite all the advantages, the gates have one significant drawback - increased protection against falling roller shutters is required. Even lightweight versions of the canvas can cause injury if it falls. Such incidents, although rare, do occur when the gearbox fails.

To avoid such situations, all mechanics and automation must undergo timely inspection; the receiving shaft is protected by a box or casing. As an insurance policy, all roller shutter doors without exception are equipped with a locking system, for which emergency shaft braking is installed.

Flaws:

1. When ice forms on the slats, roller garage doors are difficult to open, so during cold periods the surface should be treated with special compounds or a door leaf heating system should be connected.
2. When locked, the gate cannot be opened without cutting the metal, so there must be another entrance to the garage through a gate.
3. Cutting metal is not that difficult, so boxing requires additional installation alarm system if the building is located in an unguarded area.
4. Roller shutters have a slow movement and are not recommended to be used frequently: they have a limited number of cycles.

Installation

If you have an engineering education and assembly skills, installing roller shutters in your garage is not difficult. For automation, the mandatory connection of a specialist is required.

There are three main installation methods that determine the position of the box and guides:

• invoice - the box and guides are attached to the outside of the garage;
• built-in - a niche for the roll is equipped in the upper part of the opening, guides along its vertical posts, of course, if the thickness allows façade wall;
• combined - the cover for the canvas is located immediately behind the opening, already inside the garage, the movement slats are also installed in the room, immediately behind the entrance.

There are more complex options, for example, when the box is located inside the box and the guides are built-in. It all depends on the required degree of protection and the financial capabilities of the customer. Overhead installation is especially simple.

In addition to standard tools for such types of work, such as a hammer or drill, you will need: a hammer drill, a gun to make rivets, and a multimeter to connect an electric drive. Finishing involves the use of sealants - silicone and acrylic, for seams - polyurethane foam.

Preparation for installation

Before starting work, it is necessary to prepare the opening and all places for future installation of structural elements. They must be freed from unnecessary communications, cleaned, leveled, plastered, etc.

The permissible height difference on the surface is no more than 5 mm. If it is difficult to achieve such accuracy, it is necessary to provide and prepare gaskets that will correct flaws during assembly. As soon as everything dries, you get the instructions and all the parts of the gate, except for the automation.

First, mark the locations of future holes in the wall or vertical part of the opening and punch them with a hammer drill, wooden structures drilled. Then holes according to the marks plus one for the plugs are made in the guides.

Selecting a door leaf

The lamellas are selected depending on the degree of protection required for the box. They come in two types - steel and aluminum.

Aluminum

Roller rolling– the weakest, retain heat well and suppress external noise. They are used only inside industrial or commercial premises, as well as in warehouses.

Foamed or rollformed– have a relatively low weight and the same low level of protection against burglary. Suitable for boxes in protected areas.

Extruded– hollow inside, but have additional stiffening ribs, which means high protective characteristics. Installed separately standing garages or used for an entry group to the site.

Extruded ventilation– the slats are equipped with slots or holes to maintain normal air exchange. Sometimes several plates, or even all, are made of polycarbonate, which provides the room with natural light and makes it possible to observe the enclosed space. Designed for unheated boxes.

Steel can also be used as a material for lamellas. Such gates are stronger, but heavier and more expensive. Aluminum lamellas, compared to steel ones, are resistant to moisture, do not form corrosion, are lightweight, less noisy and decorative possibilities theirs is much wider.

Maximum width of the canvas at a height of 2 m:

• made of aluminum – from 2.5 to 4 m;
• from aluminum extruded – from 4.5 to 7 m;
• made of steel - from 7 to 11 m.

Installation of the structure

According to the diagram, on the surface of the wall or the upper part of the opening (for the built-in version), it is necessary to place marks for future fastenings, and drill holes in the box itself:

• overhead installation - with reverse side boxes;
• built-in - at the top of the box.

Another hole must be made for the drive cable. At the next stage, the connection with the guides occurs. Next, you need to try on the box, check the marks and punch holes. Insert dowels into them, and a protective spring into the recess for the drive.

When installing the roller gate frame, you should carefully ensure that the notches and the corresponding holes are aligned, and that the structure itself is positioned strictly horizontally in relation to the floor level. Tighten the fasteners evenly to prevent misalignment in the future.

Control and automation, if provided, are installed strictly according to the instructions, observing all safety precautions. For these works, consultation with a professional is required.

At the last moment, the web is assembled, wound onto a shaft, and the edges are passed through the tires.

Installation ends with checking the operation of the entire structure. If everything is in order, plugs and gaps are inserted and sealed, all technical seams are covered polyurethane foam.

Lock for roller gates

During assembly, automatic locks - crossbars - are attached to the last end element of the roller shutter. They are needed for a tighter connection to the floor. Side plugs and a locking cylinder allow the box to be left unattended for long periods of time. Without installing automation, a lock on a roller shutter gate is required, because the door leaf, although not by much, can be raised by a few centimeters.
