Inorganic fabric fireproof rolling shutter door
Inorganic special grade fireproof rolling shutter (double track double curtain) serves the same function as a firewall, providing horizontal fire separation. It consists of 13 parts: curtain board, seat board, guide rail, support, scroll, box body, control box, door rolling machine, limiter, door lintel, manual quick release switch device, button switch, and safety device. It is generally installed in areas where firewall separation is inconvenient. For example, open elevator halls, escalators, spacious business halls in department stores, exhibition halls in exhibition buildings, and parts of buildings with large openings that cannot use fire-resistant doors and windows. Fireproof rolling shutter doors have been widely used in construction projects for fire separation.
