The inorganic fiber fire roller shutter door is a fire separation device with a curtain made of special inorganic fire-resistant fabric. Typically featuring a dual-track, dual-curtain structure, it effectively contains flame spread and high-temperature smoke, reduces heat radiation transmission, and ensures safety for personnel evacuation and firefighting operations. It is widely used in shopping mall atriums, underground
garages, large venues, high-rise buildings, and other high-occupancy public facilities.
