Steel fire door refers to the cold-rolled thin steel plate for the door frame, skeleton, and door plate. The door is filled with non-combustible insulation material. Depending on requirements, Class A composite fire glass lighting windows can be installed. Our doors meet fire integrity and heat insulation requirements, categorized into Class A, B, and C with fire resistance durations of 72min, 54min, and 36min respectively.
Material thickness for door frames ranges from 1.2mm to 1.5mm, while door panels range from 0.8mm to 1.2mm. All hardware accessories, including hinges, latches, and closers, are strictly refractory-grade components.
