DoorHan industrial sectional doors ISD01 are especially developed for use at the industrial facilities, thereby they are capable of enduring heavy operational loads. The doors are made of sandwich panels, which consist of two galvanized steel plates, filled with foamed polyurethane. The torsion mechanism of the doors is meant for intensive operation and endures from 50 to 100 thousand of opening/closing cycles, and two steel cables have a sevenfold safety margin. The torsion mechanism, used for door leaf balancing can be installed with the help of the system Quick Fix, which is a unique development of DoorHan it permits to speed up the assembly period to the maximum (by 4 times in comparison with the analogues, offered at the doors market).
