DESFAB Bottom-rolling, top-guided hangar doors are recommended where side space permits. To accommodate specific aircraft, separate tail doors above the main doors may be installed.

The main problem being faced by the companies is the increased height of the building due to aircraft height. The traditional hangar doors have large height due to the height of the tail of the aircraft. This in whole increases the height of the building and at the same time the cost too. So to overcome this problem, DESFAB provides an easy solution of having a separate tail unit gate combined with sliding door. This kind of gate has successfully been installed at Beas. Below are some of its benefits.

Low capital and maintenance cost
Access across most of the hangar width, for full utilisation of hangar capacity
An additional height available for aircraft with higher tail height without increasing the overall height of the hangar
Fast, Reliable, safe performance. Easy operation
Long lifetime. Low operating cost
Excellent air tightness & wind resistance
Minimal maintenance need. Easy to repair
