Folding Hangar door door is a flexible soft curtain door with two layers of door fabric inside and outside. The door fabric is connected by aluminum crossbeams, vertically lifted, and equipped with movable guide rails. It is particularly suitable for large factories and hangars with layered top beams that are not in the same straight line. The flexible lifting gate (stacked machine warehouse door) is installed inside the opening and does not occupy indoor or outdoor space. When opening, the door cloth moves first, and finally overlaps above the opening. Then, the movable guide rail turns and rises to park below the door cloth. When closing, the movable guide rail is first lowered, and then the door cloth is lowered until it is completely closed.

The sliding hangar door system is mainly composed of door leaf, upper guide rail, lower rail, transmission device, upper guide wheel, driving wheel, driven wheel, door resistance, control system, power supply system, safety system, sealing system, drainage, ice melting device, etc.
