Roll up door

high-speedindoorindustrial

The leaf of DoorHan high speed roll-up doors is made of strong polyester (700 1,700 g/m2) with transparent inserts, opening the space view behind the doors. They differ by high handling capacity at minimum heat losses. Due to the high operation speed of the doors the required indoor microclimate is maximally preserved even at high intensity of their usage. The possibility of regulating the opening/closing speed of the doors in a broad range permits to fine tune their work according to the requirements. The door leaf design does not have rigid elements, which provides their operational safety. The doors possess a function of self-restoring if the door leaf drops out of its tracks, for example, in case of a blow by the automatic loader, the system of automatic restoring returns the leaf into its tracks during the next cycle. The framework and all casings are made of aluminium alloy. The design modularity allows an easy replacement of separate door elements. The installation is carried out by means of add-on assembly.
