Food Processing Plant Industrial Sectional Door

Our helical rigid shutter is available in two profile options: transparent door panel and translucent door panel (aluminum alloy foam door panel + transparent window) with an overall thickness of 40mm and a wind resistance rating of 12. This section is designed for bridge thermal insulation structure, and the aluminum alloy door curtain is connected by EPDM thermal insulation rubber, so that the door curtain pieces are tightly sealed. The innovative winding technology of the hard shutter reduces the friction between the curtain pieces. The opening speed can reach 2.35m/s/SEC, suitable for frequently opened channels. Its opening mode can be divided into spiral suction, elliptical suction, L-shaped structure, vertical structure and horizontal structure. With double spiral turbine and elliptical turbine guide rail, the door body runs quietly and smoothly. When rolled up, the door panel and the connector have no contact, no friction, no wear. If the upper space is insufficient, smooth guide rails can be used. In the case of power failure, the electrical control system can open the motor brake at any time, and the door body can be lifted by the balance system, which can effectively solve the problem that the door body cannot be opened due to power failure or failure.
