The steel fire door is framed by a steel skeleton and filled with perlite board, which is shock-resistant, abrasion-resistant and unlikely to deform.

Its door frame is rolled and bent from 1.2-1.5mm thick steel board. It shall be filled with cement and mortar during installation. The door leaf surface is made of galvanized steel panel that is stamped on a mold and bent by machine. Then it shall be welded to its stiffener and agglutinated to fire-retardant filling material - a perlite board. A fire-rated lock, a door closer, hinges (and a door closing coordinator) shall be provided. The color can be customized to match the architecture.

Grooves of door frames and door leaves are for fire-resistant seals, which will expand when the temperature rises to 60, filling the gap between leaves and frames so as to prevent from the fire and the smoke.
