High speed rolling doors

High-speed spiral doors are installed in underground parking lots, warehouses, production shops, airports and other facilities where it is required to ensure the rapid passage of vehicles and maintain the microclimate in the room. Thanks to the design and materials used, they withstand up to 150 cycles per hour. The leaf is made from aluminum sandwich panels with excellent thermal insulation properties. They can contain a transparent panel or window. The design of the door has a minimum of rubbing elements, which increases the resource to 1.5 million working cycles. Thanks to the PVC-coated roller, the door moves very quietly. Doors are produced in two modifications, depending on opening speed: up to 2 and 2.5 m/s. Both models close at a speed of 0.8 m/s.
