Sectional overhead doors are installed in garages, utility buildings, and other technical rooms. They are convenient because when opened they simply rise up, without requiring free space in front of the canvas. Another plus is that there are insulated models that have the same thermal insulation characteristics as a brick wall of one and a half bricks. And another important note - the installation of sectional doors can be done independently, with your own hands. Preferably with an assistant. It will be more difficult to cope “with one hand,” but it is also possible. Just keep in mind: if you install it yourself, it will take not the 4 hours that professional installers spend, but much more... but you can definitely do it in a day.
Why Alutech
The presented brand has a number of advantages over other companies. By purchasing Alutech gates, you will not need to order workers for further installation. You can perform all installation work yourself, following the detailed instructions.
One of the leading advantages of this company is the quality of construction. All gates are reliable. The manufacturer offers a wide range of products at attractive prices.
Types of gates
Alutech Prestige gate model
The developers of the Belarusian company designed and created a reliable, functional and at the same time accessible entrance system that meets almost all the requirements and wishes of users.
Depending on the quality of the materials used, the complexity of execution and configuration, the following models are produced:
- Prestige;
- Classic;
- Trend.
According to the lifting height, a choice of designs is presented:
- standard;
- tall;
- low.
The gates are controlled manually or electrically, with or without automation. The blade balancing mechanism is selected for specific conditions. A system of extension springs or a torsion block is selected.
Advantages
At the moment, Alutech products have no analogues. Main advantages:
- High quality.
- The gates are not afraid of the cold. At the time of production, “thermal lock” technology is used. This allows the outer metal coating to be separated from the inner one. This provides reliable protection from the cold and provides thermal resistance in the form of a polyurethane layer.
- Do not corrode. The top layer of the structure is covered with zinc, which was applied there using galvanization.
- Wide selection of products. You can choose a product with a smooth or classic surface. It is possible to cut out a window of any shape, repaint the gate or adjust the size.
- Customers have the opportunity to choose fittings. For example, determine a specific shade for handles, locks, etc.
Constructions
Alutech produces two groups of gates: “Classic” (for established buyers) and “Trend” (for those who want to save money and still get normal quality). The first selection uses 4.5 cm thick panels, and the components are made of stainless steel. Such products can be safely installed even in polar regions; they are guaranteed to withstand the effects of hurricane winds.
Western European concerns can offer similar quality, but their fees for automatic entrance systems of this level are significantly higher.
The “Trend” line is made on the basis of 4 cm panels; this is the optimal solution for a garage located in a temperate continental climate. All main parts are made of zinc coated steel. The products will not withstand winds of 40 m/s, but they are not afraid of very strong gusts. Such properties are achieved not by making the structure heavier, but by reliably sealing it with polyurethane foam. The quality is higher than that of similar gates made in the Russian Federation, and things are better with automation.
The lock supplied is a mortise-type deadbolt in a deadbolt format. Closing and opening is possible only with the original key; In all versions, the gate can be locked and unlocked both inside and outside. The locking device is inserted as securely as possible. Alutech designers refused to use a single piece of fabric; they preferred to divide it into autonomous panels. This solution made it possible to radically increase strength compared to monolithic versions.
Alutech engineers have prudently added a counterweight to the design, making opening easy and quick. The plowing course, directed rigidly vertically, ensures free access and almost close approach. Assembly with the participation of professionals occurs as quickly and reliably as possible.
Kinds
At the moment, Alutech offers its customers two types of gates:
- Classic . Torsion springs, responsible for compensating the mass of the web, are located above the structure. With the help of a coupling, you can easily adjust the location of the shaft parts during installation work. All springs included in the kit are connected to ratchet couplings. This is required for safety reasons. That is, if the spring breaks, the coupling will become an obstacle to the shaft and will be able to hold additional mass. It is worth noting that the Classic type of gate can be mounted in three ways.
- Standard . The balance of the canvas depends on the springs that stretch it between the panels and profiles. Because of these elements, the canvas will never go down on its own.
The installation work of the presented design is quite simple and does not require much experience. It is important to follow the attached instructions.

Subtleties of assembly and configuration
In order for sectional doors to function properly, it is worth remembering the following rules:
- During the assembly process, it is important to securely fasten all parts of the door system. This is a simple but effective prevention of misalignment, in which the blade seizes or jams.
- It is recommended to use hardware of the sizes specified in the instructions. Changing the parameters of dowels, bolts and screws leads to incorrect operation of the mechanism.
- If it is necessary to level the structure, metal plates are suitable. It is unacceptable to replace them with wooden elements or polyurethane foam.
Setting up automatic gates is carried out in three stages:
- Fix the blade in the lower position and adjust the sagging of the cable.
- Adjust the limits of movement of the electric drive using the remote control.
- Adjust the spring tension: loosen the fixation, and then scroll the spring to the desired tension level.

Preparation for installation
Installation work of the structure of the presented company must be carried out in those garage premises where the opening meets the accepted criteria:
- the opening and walls must be brick, metal, concrete or made of slag;
- load-bearing structures must be characterized by increased strength and rigidity. In the future, they will be subject to stress;
- the sides on the sides must have a strictly vertical position;
- the ceiling must be level.
For installation work you will need:
- perforator;
- drill;
- keys;
- hammer;
- tape measure, building level;
- scissors cutting metal;
- drills and drill for metal;
- screwdrivers.
Briefly about the main thing
Self-installation of sectional doors is a labor-intensive, but doable task if you understand the principle of operation of the mechanism and have certain skills. To avoid problems, the manufacturer supplies its products with an installation card, which describes the assembly process step by step.
For a high-quality result, you need to stock up on the necessary tools and prepare the room. The design of sectional doors is sensitive to the slightest distortions, so it is important to make sure that all planes of the opening, floor and ceiling are truly horizontal and vertical. Installation begins with the assembly of the sectional canvas, then the guides are assembled and installed. At the end, the torsion mechanism is assembled, the blade is secured and final adjustments are made.

Fastening the guides
Initially, it is necessary to check the complete set of the gate. Then calculate the further location of the vertical profiles. To do this, place the bottom panel against the opening, and do not forget about aligning the side cuts.
Make some marks on the walls. Measure a meter from the floor and draw a vertical line to the ceiling. Along the finished line, drill small holes required for subsequent installation of profiles.
Assemble the frame on the ground, this will make the work much easier. The supporting structure consists of two support posts, vertical profiles, a cover plate, inserts for sealing, radius profiles and horizontal guides. The vertical part consists of a support post, a strip and a strip intended for measuring.
How to install guides?
- insert the seals into the strip and fasten it to the supports with bolts;
- then assemble and fix the bar using M8x25 bolts;
- then you need to install the prepared structure. Place it against the opening and align it on the posts where you left chalk marks at a level of one meter from the floor;
- it is necessary to drill holes along the opening. This is required for further fastenings;
- align the frame, insert the bolts and tighten;
- remove the measuring bar;
- After fixing the frame, install horizontal guides. Secure the radius profile and attach it to the guide using bolts from the inside;
- attach two strips to the vertical posts. Use the mounting plates;
- measure the horizontal level using a building level and install the rear jumper;
- Using hangers, attach the frame to the ceiling and secure it.
Measurements and dimensions
Sectional doors are also called overhead sectional doors. This name is due to the structure and principle of operation. The door leaf consists of separate sections, movably connected to each other. Hence the word “sectional” in the name. When opened, the sections move upward along the guides, smoothly moving to the ceiling. When open, they are held on the ceiling. And this is the reason why they add the word “lifting” - they rise up.
General design of sectional doors with torsion springs
Sectional doors consist of two parts - the door leaf and guides along which the door leaf moves when opening/closing. To install sectional doors yourself without any problems, you need to carefully measure the opening. There is nothing particularly difficult in this part. All you need is a tape measure, a plumb line, and if you have one, a laser level.
Everything is clear with the terminology, the design is clear in general terms, now in more detail about the measurements and preparation of the opening, without which the installation of sectional doors simply cannot be done.
What and why to measure
To order overhead sectional doors, you need to measure the following distances (shown in the figure):
- Height (H) and width (B) of the opening. Everything seems to be clear here, the measurements are simple. But, for normal operation of the gate, the planes of the opening must be parallel. The side walls must be strictly vertical, the floor and lintel must be strictly horizontal, without deviations or sagging. Verticality and horizontality can be verified using a level or plumb line. You can also control the parameters of the opening by making changes at several points. If the data matches down to the millimeter, everything is fine. If not, you will have to prepare the opening - level it and only then measure and order sectional doors.
What parameters are needed and important - Ceiling (lintel) height. The lintel is the distance from the top of the opening to the ceiling (h). The optimal ceiling height is 400-600 mm. In this case, you can install the cheapest and, at the same time, the most reliable standard lifting system - standard.
- The distances from the edge of the opening to the side walls (on the right (b2) and on the left (b1). Also called “shoulders.” Guides are mounted on the sides of the opening and the distance from the opening to the side walls affects the choice of their design and installation method.
- Depth of entry (GV or L) into the room. This parameter is important, although it is often omitted. This is a calculated value that depends on the height of the opening and the type of lifting system being installed. It is calculated according to the following rules: a certain number is added to the height of the gate opening: the gate area is up to 8 m2, add 400 mm.
- the gate area is more than 8 m2 - increase by 450 mm.
- low rise (depth of entry) - need to add 550 mm;
- high lift - you need to add 65 mm and 850 mm.
With standard installation, the installation of sectional doors does not affect the opening
Once again we draw your attention: the last parameter is worth paying attention to - the depth of the room in which the sectional doors are installed cannot be less than this value.
When installing the drive
If automatic opening is planned and the drive is conventional, you will also need a place for it (in the figure below it is indicated by the letter W).
The space inside the room must be sufficient to install the guide system and drive if an automated modification is used
To give you guidance, to install the drive on the ceiling, the minimum room depth should be from 3290 mm to 4400 mm (for different lifting systems). For shallower rooms, there is another solution - installing an axial drive. It is more expensive, but more powerful and requires installation space only on the side of the opening.
We read about choosing the lifting height in this article.
These are all the necessary measurements. As you can see, everything is not difficult. But it is very important that the gate opening is smooth, without significant deviations. The condition of the floor and ceiling (in the area where the gate is installed) is also important. For the ceiling, it is important to align the part on which the ceiling guides will be mounted. The floor must also be level so that the frame does not warp. If there are irregularities, you will have to prepare the gate opening, only then take repeated measurements and order the gate.
Installation of panels
The second stage of installation work involves installing the canvas. Attach hinges, brackets and a roller system to the panels. The main thing is to follow the instructions. This way you will avoid mistakes and waste of additional time.
The hinges should be screwed onto self-tapping screws. First you need to install the bottom panel. Insert it into the guides. Then place the middle panel, securing it to the installed one. Fix the structures securely and install the final panel. Finally, thread the cables through the holes on the sides and tighten the fasteners.
Features of choosing accessories
If the choice of color and pattern is an obvious process, then the choice of fittings is quite complicated. The main thing is to understand that most of the load falls on moving parts, so they must be of excellent quality.
Advice. The risk of making the wrong choice or installation errors is great. A heavy blade may fall on the vehicle or injure a person.
During installation, it is not allowed to use used parts or purchase components from different manufacturers (they may be incompatible). Before purchasing, you need to check whether the parts are sold separately in case replacement is necessary.
For reliable operation of sectional doors, high-quality fittings are important
A useful addition that ensures safety is a system that prevents pinching of fingers and cable breakage.
Installing springs
The final stage is assembling the torsion shaft. First you should install the spring, then the coupling half, the retaining ring, the intermediate bracket and the ring again. Make sure that all parts are installed level and tightly secured. Pay attention to the springs that are attached to the ratchet couplings. It is important that they do not fly off. Also install the second part of the shaft above the opening. Pass the cables through the holes made and secure them with brackets.
To adjust the Alutech gate, you need to tension the door leaf (lift and loosen the cables). Use stands and level the canvas. Adjust the cables based on the required length. Tighten the drum screw and remove the stands.
Check for correct installation work. Open and close the structure a couple of times in a row. Self-installation of the presented gates does not require special knowledge or experience. All you need to do is follow simple instructions.
Minuses
Significant disadvantages include the relatively high cost of some models, which, however, is balanced by reliability and ease of use. Another disadvantage is the need for periodic maintenance, but any mechanical system requires it.
Experts do not recommend self-installation of garage doors, citing the following considerations:
- The car owner does not have the necessary knowledge and practical skills; he does not have special equipment. Installation “in your own way” will lead to unstable operation of the gate structure.
- Self-adjustment of the drive is most often done by eye. An incorrectly adjusted mechanism, in the event of unauthorized closing, can cause damage to people and equipment.
- The manufacturer will not be able to judge the reliability of installation made by an outside person. By performing assembly and debugging yourself, you will lose warranty service.

Therefore, you can install DorHan gates (or any other) on your own only if you have the appropriate experience and knowledge in such work. The desire to save money, not supported by the appropriate skills, cannot be a reason to install it yourself.
