Sectional door is widely used for its high practicality and high-end appearance, and is suitable for a wide range of building exterior and interior doors. However, many of our friends will ask us if I don't have enough top space to install it. How much top space is needed for sectional overhead door installation actually depends on the type of track of the door, so let's discuss the type of track of the sectional door next.

Basic information on sectional door tracks

l Provide the most suitable and accurate track form according to the structure of different buildings.

l The track generally consists of a vertical track, (horizontal track), torsion spring system.

l The rollers fixed to the ends of the door panels run in precise positions on specially designed Hohmann sliding rails, ensuring that the door panels will not fall off the rails when running in any position.

l The rails are all bolted to the wall and can be easily and economically replaced if part of the rail is damaged.

Types of sectional door tracks and applicable headroom

1. N track

Vertical and horizontal tracks are basically equal in length, and when the door is fully opened, almost all the door panels are laid flat on the horizontal track, suitable for the case of small space at the top.

2. H track

The length of the vertical track is longer than the horizontal track, after the door is fully opened, part of the door panel is on the horizontal track, and part of the door panel still stays on the vertical track,suitable for the case of large space at the top.

3.V track

The door always runs on a vertical track, the torsion spring shaft is located at the top of the vertical track,suitable for the case of enough space at the top.

4.VU track

l The door always runs on a vertical track, suitable for situations where there is sufficient headroom.

l The torsion spring shaft is located in the centre of the vertical track for easy installation, repair and maintenance.

5.HU track

l The length of the vertical track is longer than the length of the horizontal track, after the door is fully opened, part of the door panels are on the horizontal track and part of the door panels are still on the vertical track, which is suitable for the case of large space at the top.

l The torsion spring shaft is located in the middle of the vertical track, which is convenient for installation, repair and maintenance.

So of course it is possible to install a sectional door if there is not enough space at the top.SEPPES has developed a variety of installation solutions taking into account the needs of different companies. If you also want a unique solution, you can leave a message to consult us.
