Fire doors are mainly used in commercial buildings, residential buildings, public facilities, industrial plants and other places. Over time, the design and manufacturing technology of fire doors have been continuously improved. Traditional fire doors are mostly made of metal materials, such as steel plates, to provide good fire resistance and structural strength. Subsequently, the materials of fire doors have diversified, including steel, wood, fiberglass, etc., providing more choices while meeting fire resistance standards.
