鉄の防火扉

As we know, steel fire doors are what we call iron fire doors. The door frame, door leaf frame and door leaf panel made of steel materials are used for fire doors. The door leaf is filled with non-toxic and harmless fireproof and thermal insulation materials, and equipped with fireproof hardware fittings to form a door with certain fire resistance, so its fire resistance is very good.
