The leaf of Hulk high speed roll-up doors is made of strong Ryan polyester (700 1,700 g/m2) with transparent inserts, for a clear view through the doors. They have high handling capacity with minimum heat losses. Due to the high operation speed of the doors the required indoor microclimate is well preserved even during high intensity usage. The possibility of regulating the opening/closing speed of the doors in a broad range permits to fine tune their working 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 loader, the system of automatic "Restore" returns the leaf into its tracks during the next cycle.
The framework and all casings are made of aluminum alloy. The design modularity allows an easy replacement of separate door elements.
