Rapid vertical roll-up door
EVOLUTION. The door had been designed to have maximum dimensions of 4 m of width and 4,5 m of height and its main features are the self-repairability and the absence of the safety rib. In case of collision against the door the coat gets out from the upright frames together with its patented horizontal elastic reinforcement bars, and next "open" command shall bear the coat to return into the uprights by simple gravity. In case of violent impacts (to be avoided by the known safety systems) the human intervention may be needed. The mass descending on possible obstacles is so insignificant that there is no need of safety rib. The coat is class 2 polyester, thermowelded sectors 700 gr/sqm, reinforced by flexible bars with patented wind-keeping system. Available colours: BLUE similRAL 5002, YELLOW similRAL 1021, RED similRal 3002, GREEN similRAL 6026, WHITE similRal 9016, GREY similRal 7040 Quick, light and secure, but very strong: the average opening and closing speed is of 1 m/s. The special coat of new concept, included the elastic retention bars, may cause a chock of only 40 N in average against the possible obstacle, further distributed by the bottom soft edge.
