What kind of ceiling do you have? This is how communication begins with a person who has decided to order sectional doors. The fact is that to place the gate structure, space is required on the right, left, and most of all, above the opening. And yes, this place above the gate opening is the lintel.
That same notorious lintel.
What it should be depends on the following parameters
Your opening is up to 8m2
For small household garage doors area up to 8m2 tension springs are installed. The ceiling height should be not less than 100mm(for manual lifting) and 125mm for gates with a drive. This is in theory. But in practice, in order not to catch millimeters, do 150mm.
Your opening is larger than 8m2
For gates more than 8m2(torsion springs are installed) needed lintel 210mm, but it’s better to make 250mm. Don't forget that walls can be crooked.
An example of a door with torsion springs. Much more space is required above the opening.
Do you want to build a gate
All gates with a wicket, regardless of size, require a lintel not less than 210mm, (standard installation).
Gates with a wicket always come with torsion springs.
What to do if you have a high (more than a meter) ceiling?
If you have a lintel of 500mm or more, you are incredibly lucky and have access to the so-called high installation, when the gate first rises as far as possible to the ceiling, and only then leaves parallel to the ceiling. See the picture, it’s clearer.
High installation. Factory drawing.
- Advantage: the gate does not hang over your head, no long hangers are needed.
Disadvantages: high lift is not available in all series, and for it you need to pay an additional 8% of the cost of the gate.
What to do if you have a low (less than 210mm) ceiling?
What if you have a ceiling less than 210mm, but need a gate larger than 8m2, or need a wicket? will help you low installation!
This is when the shaft with springs is located at the back, deep in the garage (see picture). In this case minimum size the lintels will be 100-130mm, depending on the type of control.
- Disadvantage: surcharge of 5%.
Low installation. Factory drawing.
Rule 2. What kind of shoulders are you?
The shoulders are the lateral distances from the edge of the opening to the wall. For domestic gates, in most cases you need a minimum of 120mm, it is better to leave 150mm or more. Otherwise, it will be difficult to reach with a wrench in order to tighten the fasteners of the corner posts.
Rule 3. How deep is your garage?
The depth of entry of the gate into the room. A very insidious quantity. They don’t always pay attention to it, but if it’s not enough, the gate will simply rest against the back wall of the garage. That's why we always measure the depth of the garage. It must be no less than:
opening height + 400mm (for gates up to 8m2)
opening height + 450mm (for gates larger than 8m2)
opening height + 550mm (if you have a low installation)
opening height - (ceiling height + 265mm) + 850 (if you have a high installation)*
And don't forget about the electric drive! He needs space too. Depending on the model and opening height W value will be from 3290 to 4400mm. (see table). Or call us, we will tell you!
The depth of the drive penetration into the garage depends on the brand and manufacturer of the electric drive.
Rule 4. The opening must be level!
The opening must be in the same plane, without sagging or depressions. It is best to use it before installing the gate plaster on the beacons.
It is better to plaster such an opening before installing the gate.
Here the customer prudently plastered the plane of the opening.
Places protruding beyond the plane of the opening are indicated by arrows. It is necessary to cut the base to a vertical line.
Rule 5. There must be somewhere to attach it.
If it is concrete, solid brick, or even foam block there is no problem. It's worse when it's a slotted brick. There are two options - either weld the frame from the corner and attach it to it, or plaster it and attach it to the mortar joint. The first option is more reliable, but more expensive, the second is cheaper, but depending on your luck. If during the installation process it turns out that the fasteners do not hold, you can use chemical anchors.
The opening is reinforced with a corner.
Mounting in hollow brick. The arrows show the installation locations of chemical anchors.
Rule 6. If there is no opening at all.
This also happens, and quite often. In this case, a U-shaped frame is welded from professional pipe 100x50 or 100x100. Naturally, all the necessary lintels, shoulders, etc. are maintained.
The photo shows the preparation of the opening with a U-shaped frame made of corrugated pipe 100x50x3.
Rule 7. About suspensions.
The gates do not hang from the ceiling anyhow, but on special telescopic hangers. They are different lengths. By default, the kit includes CS1, 300mm long. If you have a lintel (now you know what it is) up to 300mm, then everything is OK. If more, then take a different size. There are only 5 of them, for 500, 800, 1000, and 1500mm. Sometimes they are hung on a mounting angle, which is also an option, but remember to make a trapezoid for rigidity, and do not make them too long (more than 1500mm), the structure will be unstable.The hangers are attached in pairs, the first pair is hung at a distance of 900mm from the opening, the second at a distance equal to the height of the opening + 250mm.

A new garage door is quite expensive, so choosing one needs to be done wisely. Sectional doors are easy to use and take up little space in front of the garage. See our instructions on how to install sectional doors step by step.
Attention! Gate designs different manufacturers have their own assembly features, at the end of the instructions we will show detailed video instructions for assembling sectional doors with another mechanism.
Before buying a garage door, you need to know what size they should be, and also decide which opening method will be most convenient for you. You can choose between four types of gates: up-and-over, tilt-up, sectional or roll-up. Important role The installation of the gate also plays a role.
Sectional doors
The main advantage of these doors is that they do not require space in front of the garage to open and close them. This solution is especially useful for those who drive into the garage directly from the street.
If you are planning to purchase a drive - even at a later time, you must take into account that the running bus with drive requires additional free place under the ceiling.
Rail fastening
To stabilize the gate frame during installation, an end rail (guide) is used, which is temporarily attached to the bottom of the side rail. When tightening profiles, their deformation must not be allowed.
Installing the frame in the garage. We install the frame created in this way inside the garage - vertically next to the opening, carefully align it and secure it.
Fastening side profiles. The installation of the gate starts from the floor; the side profiles should be secured using brackets and bolts with dowels.
Removing the bottom tire. When the gate frame is rigidly attached to the opening, remove the bottom rail.
Fastening the guides
After removing the bottom rail, the side guide rails are installed.
Installation of the guide rail arc. We mount the upper side guide rail.
Fastening the sidewalls and the final tire. After accurately installing the frame and side rails, we install the top rail, mounting it to the ceiling.
Placing gate segments in guides
We place the gate fragments in the installed guides, starting from the bottom. To ensure that the fragment adheres well to the floor, first insert a gasket into its lower edge.
Mounting loops. The gate segments are connected by correspondingly formed hinges in places where there are pre-prepared holes for self-tapping screws.
Fastening guide rollers. Attach the hinges to the roller by first inserting it into the profile of the wall roller frames.
Special hole for mechanical gate locking system
In the frame, one of the lower sections has a special hole that allows you to install a mechanical gate locking system.
Tension spring installation
After connecting all the segments and trial run We install the appropriate tension spring, which allows you to adjust the weight balance of the gate leaf.
Steel cable fastening. Connects gate leaves with springs steel rope. Its ending is fixed on the lower segment.
Determination of cable length. To determine the length of the cable, open the gate to the required height. At this time (when the cable is not tensioned), the gate must be fixed.
Attaching the cable to the upper frame. The cable is attached to an element on the upper frame. A trial opening and closing of the gate will indicate if the cable requires further adjustment. If the cable is tensioned correctly, the half-open gate should stop. The tension of the cable can be adjusted by changing the position of the seal.
Completion of installation
After assembly, make sure that the gate opens and closes easily without losing the guides.
When purchasing garage doors, focus on sectional garage doors, which have many advantageous differences from other designs. To install a gate of this type, you need to know about some nuances, which we will now consider.
Design features
Sectional doors are a door leaf with sections connected by hinges, moving along guide rails.
What does the structure consist of:
- Canvases of two steel sheets with thermal insulation made of polymer foam.
- Suspensions and guides. Suspensions provide rigid fixation of sections in the space under the ceiling. Guides allow sections to move.
- Spring device. Balances the door leaf. This element allows you to manually open or close the gate.
There are two types of canvas:
- Panoramic canvas.
- Sandwich panel fabric.
The first type is made from extruded aluminum profile with inserts made of translucent material.
The second type is sandwich panels equipped with an auxiliary layer of insulation to prevent the gate from freezing in winter. The safety and efficiency of the gate depends on the thickness of the panels. Unlike the first option, collapsible gates made of sandwich panels can have a variety of designs, so you can choose them according to your needs. common interior the buildings.
Many advantages
- They save space, because to open and close ordinary swing gates it takes quite a lot.
- They have a high level of sound insulation.
- High degree of protection against burglary and intruders entering the garage.
- Safe to use.
- High thermal insulation qualities due to good tightness.
- Large assortment of colors.
What variations are found?
Gates differ according to the type of control:
- manual;,
- automatic;
- remote.
The gates are opened automatically using an electric drive. In addition, automatic sectional doors are divided into:
- gates with remote control;
- gates with stationary remote control;
There are most modern models, remote control which is made from a mobile phone.
All sectional garage doors have a spring mechanism that helps open the door manually.
In addition, the gates can be insulated or cold-type. Insulated ones are installed in heated garages, and at the same time they very well insulate the room from cold street air.
Cold-type gates are installed in parking lots and garages without heating.
Gate installation: how to prepare
Installation of sectional doors can take place in any premises, with any openings and roofs of various slopes. The gate can open at right angles, vertically (top opening), or at an angle.
Installing the gate is not difficult, and it can take from two to six hours. Everything will depend on the number of sections.
If the gate was purchased separately, without ordering installation, then it comes with detailed instructions, which needs to be studied and checked for the presence of all components.
Tools for installing sectional doors:
- Set of wrenches.
- Level.
- Pliers.
- Roulette.
- Drill.
- Hammer.
Installation steps:
- Preparing the doorway, strengthening it and plastering it if necessary.
- Assembly of sectional doors.
- Checking the correct installation of the gate.
Before you begin installation, you need to check the opening into which the gate will be installed. It must meet the following requirements: the shoulders and lintels must be in the same plane, the openings must be plastered, the horizontal and vertical lines must be level.
Instructions
- As soon as the base for installation is ready, we apply markings in the places where the fasteners will be located.
- We install the guides. They must be installed strictly level.
- After the fasteners are installed, you can begin assembling the gate leaf itself. Start from the bottom section and continue to the top level.
- After installation, we check each section with a level to prevent distortions.
- To close the resulting gaps, special metal gaskets are used, but you can also use wooden slats.
- When the gate is installed, we begin installation of the lifting mechanism and control system.
- As soon as the installation work is completed, we check the functionality of the gate.
How to determine correct assembly
- After assembly and installation, check your sectional doors for fit throughout the entire opening: there should be no drafts or cracks - complete tightness.
- Check the bottom clamping mechanism. After closing there should be no gap left between the door leaf and the floor.
- To check the gate for gaps between sections, go into the garage, close the gate and carefully inspect it.
- Opening and closing of sectional doors must be free and smooth, and the door leaf should not get stuck. If the blade does not move well during operations, check the level of the guides.
- Check the spring mechanism for balancing and adjustment. To do this, we lower the canvas, and if the springs hold it at a level of a meter from the floor, the mechanism is configured and adjusted correctly. There is no need to think that it is better to tension the springs all the way - this can lead to rapid wear and failure of the spring mechanism, and with it the gate.
How to adjust
In order for your gate to serve for a long time and operate smoothly, it needs to be adjusted. Many sectional door models are equipped with special mechanism, which protects the canvas from falling. If this mechanism is triggered, the tension cable begins to sag.
For good operation of the gate mechanism, all cables must be tensioned. Before you begin to tighten the cables, lower the blade and loosen the spring mechanism. The gate design has a bracket in which there is a ratchet clutch, which is responsible for tensioning the cables.
The bracket fixing screw should be unscrewed using a hexagon. Then remove the coupling from the lock and screw the screw into its original position.
We do the same with the drum screw, which is unscrewed until the moment of free rotation, which will allow the cable to be wound back onto the drum. The cable should not sag much; as soon as the minimum sag is achieved, install and tighten the screw.
There are situations when sectional doors sag unevenly, this can be eliminated. Unscrew the coupling coupling bolts and turn the shaft from the sagging side.
It is also worth saying that this type You can also make the gate yourself. But this process is very labor-intensive and costly; in the end it turns out that it is cheaper to buy ready-made sectional doors.

Installing sectional doors will allow your garage to acquire a number of important advantages:
Burglary resistance. The design will reliably protect the premises from intruders.
High level thermal insulation. The garage will be maintained comfortable temperature. Thermal insulation performance is comparable to the characteristics brick wall 600 mm thick. The gate will not become covered with frost and freeze.
Ease of use and functionality. Managing the system is easy and simple. Gates equipped with automation open and close using remote controls.
The canvas is securely fixed using a chain or electromechanical devices. None additional accessories not required. In winter you won't have to clear snow. The gate opens vertically upward. If necessary, you can install a model with a gate, mortise windows, photocells and alarm.
Aesthetic appearance. Choose the product that best matches the color.

Sectional door design
The above advantages are determined by the design features of sectional doors.
Image No. 1: diagram of a typical sectional door (standard lift)
The canvas is balanced and moves up/down using spring mechanisms. To fix the sash in the open state, there are guides that are attached to the ceiling. To reduce resistance, sandwich panels are equipped with rollers. They provide smooth and silent movement.
Spring mechanisms reduce the weight of the canvas. This explains the fact that the flap can be easily opened manually or using a low-power electric drive. The design of sectional doors includes fall protection. If the cable breaks, the web will be blocked by the ratchet couplings.
Automatic sectional doors have a more complex design.
Image No. 2: diagram of automatic sectional doors (standard lift)
Manufacturers complement their products with drives with control units, automatic locking mechanisms, warning lights and sensors. During a power outage, the gate can be opened and closed manually. A special key unlocks the security mechanism.
If desired, manual or automatic sectional doors can be equipped with wickets and windows. Manufacturers offer a wide range of modifications.
Image No. 3: one of the possible modifications of sectional doors with windows and a wicket
Important! Please note that the presence of additional structures will increase the cost of the product by 35–40%.
Features of sandwich panel production
The sandwich panel consists of two galvanized steel sheets. Insulation (foamed polyurethane) is placed between them. On the outside, protective and decorative coatings are applied to the sheets.
Image No. 4: sandwich panel design
To increase the level of thermal insulation, almost all manufacturers produce special elastic plugs. During installation, they are placed between the sash elements to ensure there are no gaps.
Threshold (lower) panels are equipped with elastic seals. They are resistant to temperature changes and prevent the gate from freezing to the floor in winter.
Important! Manufacturers produce sandwich panels of various thicknesses. 45 mm is ideal for regions with harsh climates. Such panels are intended for arranging gates of heated buildings.
Sections with a thickness of 40 mm or less are suitable for use in “cold” rooms in regions with a temperate climate.
Installation of sectional garage doors
Garage door installation can be done different ways. The choice of design location depends on the characteristics of the room. There are 4 types of installation of sectional doors.
Image No. 5: types of installation of sectional doors
Vertical lift. This method of installing the canvas is ideal for high rooms. The gate will take up a minimal part of the space.
High rise. This option will cost more. The method is used in cases where the ceiling height is not enough for vertical installation canvases. The cost of installing sectional doors increases due to the need to use horizontal guides, hanging brackets and more consumables.
Standard lift. This installation option is most common because many garages have low ceilings. The installation cost is practically no different from the previous option.
Low rise. This method is relevant for rooms with very low ceilings or in cases where it is necessary to clear the entire doorway from the canvas.
After you have chosen best option implementation, pay attention to the manufacturers. Modern market filled with products various companies. We hear about Hormann, DoorHan and Alutech.
Important! If the dimensions and characteristics of the opening and garage meet the requirements for installation of one of the sectional door models produced by the selected manufacturer, you are in luck. You can make a purchase. Otherwise (this is the majority), you will have to order gates made according to an individual project.
Preparatory work before purchasing and installing sectional doors
Measurements
Before purchasing sectional doors, please necessary measurements according to the following scheme.
Image No. 6: diagram of measurements required for the purchase and installation of sectional doors
Measure the H value. Please note that the resulting value will only determine the height of the canvas, and not the entire structure as a whole.
Measure the ceiling (h). The installation method will directly depend on its height. The minimum h value for installing sectional doors using the standard method is 30 cm. If the lintel height is less, you will have to order a design with a low rise.
Determine the width of the opening (B). Increase the resulting value by 4 cm (2 on each side).
If the width of the door will be as close as possible to the width of the garage, make sure that the dimensions of the technical gaps b1 and b2 meet the requirements. Minimum - 8 cm.
Measure the depth L. If you plan to install manual sectional doors, then the minimum value L should be 50 cm greater than the opening height. Installation automatic designs requires increased depth (H+100 cm).
After taking measurements, order suitable sectional doors. It will take several weeks to make them. During this time you will have time to prepare the opening for installation.
Preparing the opening
Plaster the ceiling and walls (if this has not been done previously). After installing a sectional door, you will not be able to access closed areas without dismantling the structure.
Make sure that the vertical and horizontal positions in the opening are strictly observed, and the corners are in the same plane.
Finish the ceiling and walls with a 75mm metal corner.
Check the level of the floor. Maximum allowable error-1 mm. This is necessary to ensure that the lower section of the gate fits as tightly and evenly as possible to the floor.
After completing the preparation of the opening, take care of the availability necessary tools.
Note! If you are not confident in your abilities, order measurements and preparation of the opening from professionals. Even the slightest errors lead to distortions. If the sectional leaf twists even a little, the service life of the sash and mechanisms will be significantly reduced. You will either have to reinstall the gate or frequently repair the structure.
Installation tools
When installing automatic sectional garage doors, you cannot do without:
-
riveting tool;
two mounting gates (0.5 m);
-
stepladders;
-
pencil for marking;
side cutters;
pliers;
a set of wrenches;
universal and terminal screwdrivers.
drills with a hammer drill;
screwdriver;
a set of drills for metal and concrete;
To ensure safety, you will need gloves (regular and rubber), helmets and safety glasses. The recommended number of installers is 3 people.
Sectional door assembly
Assembling sectional doors requires a responsible approach and strict adherence to all provisions of the instructions provided by the manufacturer. This will allow you to get a stably working structure that will last the required period.
The installation process of sectional doors is divided into several stages.
1. Assembly and installation of the supporting frame
The supporting frame of sectional doors consists of:
support posts with sealing inserts and vertical guides (1);
radius profiles (2);
horizontal guides (3);
rear jumper (4);
side brackets (5).
Image No. 7: diagram of the supporting frame
Install all elements as specified in the sectional door installation instructions from the manufacturer.
2. Installation of the shaft with springs
Image No. 8: Shaft mounting diagram
Assemble the right and left parts of the shaft and secure them according to the instructions.
Install the snap rings against the inner races of the side bracket bearings and secure them by tightening the screws.
Lock the ratchet clutches using special pins.
Note! Remove the locking pins only after completing the gate assembly.
3. Assembling the door leaf
Image No. 9: canvas assembly diagram
Install the bottom section. Place the panel and check horizontality using a level. After this, connect the section to the lifting mechanism.
Install the remaining sections according to their sequential numbering. Carefully follow the dimensions and recommendations, as even the slightest deviations lead to distortions.
Note! To correct defects, do not use foam or planks. Only iron spacers will do.
After assembling the leaf, install the upper brackets and make sure that the sash fits snugly against the opening lintel.
4. Adjustment
Adjust the tension of the cable and springs according to the instructions.
Important! During the adjustment process, be careful and use a tensioning tool of the specified size.
Check the gate balancing. To do this, raise the canvas to half the height of the opening. The sash should be held in this position. If the blade lowers or rises, increase or decrease the spring tension by 1-2 turns and repeat the test.
5. Attaching additional elements
Secure locks, hinges, handles and latches into in the right places. Attach the spring stops according to the instructions.
Perform a final balancing check to ensure there are no gaps.
6. Installation of automation
A typical layout of automation elements looks like this:
Image #10: typical diagram automatics for sectional doors
Standard automation consists of:
electric drive (1);
control unit (2);
distribution box (3);
microswitches for spring breakage (4);
cable break microswitches (5);
wicket sensor (6, if equipped);
optosensor emitter (7);
optosensor receiver (8).
Install the main and protective elements according to the instructions. After finishing installation work check the functionality of the automation in all programmed modes.
Installing garage doors yourself requires knowledge and experience. Often, due to errors made during the installation process, structures fail almost immediately.
If you are not confident in your abilities, saving on the cost of installing sectional doors will not lead to anything good. Contact a reliable construction company in Moscow. Professional specialists They will do everything much faster and provide a guarantee for the work performed.
Carefully follow all instructions in the instructions. Even small mistakes can lead to skewed gates and failure of the structure.
Work areas must be free of pipes and electrical wiring.
When choosing sectional doors, pay attention to such parameters as thermal insulation properties, strength and durability.
For a garage it consists of several typical stages. In this material we will tell you how to install sectional doors, and.
Dorhan
The installation of Dorkhan gates is shown in detail in the video and instructions from the manufacturer, who promises that even a beginner can handle the installation process of the sectional door.
The gate series is characterized by quick installation, lasting 20 minutes.
The manufacturer attaches the fittings at the factory, reducing the owner’s time costs and the overall labor intensity of the process.
Yett 01
Yett 02
After the tools are prepared, the lower, middle and top panels. Then the vertical guides are installed. First of all, check the evenness of the floor of the opening, and then attach the bottom panel, against which the vertical guides are installed.
Then the horizontal guides are installed, after which the support brackets of the torsion mechanism are secured. The panels are mounted after the spacer bushings, and then the torsion mechanism is installed.
Fastening to the ceiling is carried out using corners or universal brackets, after which the tension of the cables is adjusted, C-profiles, buffers, shock absorbers, handles and latches are installed. Do-it-yourself installation is completed by checking the movement of the blade.

The video consists of two parts:
Alutech
Answering the question “how to install Alutech gates,” many users noted that the complexity of the procedure is extremely exaggerated by the manufacturer. For installation you will need a drill, wrench and a number of other necessary tools given in the instructions.
First you need to prepare the opening ( ideal option is brickwork or concrete), and then construct the frame, secure the guides and assemble the panels, starting from the bottom.
Official video from the manufacturer.
A more detailed and complete video with Russian voice acting: primarily relevant for beginners.
Hormann
Assembly of Herman gates (like any sectional door leaves) does not allow the use polyurethane foam and wooden pegs for adjusting the structure in plane. To do this, you need to use metal pads. Before carrying out work, the doorway must be marked in the places where the frame will be attached to it.
Every millimeter must be adjusted, the slightest distortions are not allowed.
Before installation, you need to assemble the supporting frame and securely fasten it in the opening. Next, install the ceiling part of the supporting frame and begin assembling the panels. According to users who performed the installation themselves, the instructions are so clear that even a beginner can handle it.
