Steel fire door characteristics:
Steel fire doors use cold-rolled plates to make door frames and door leaf panels. The door leaves are filled with non-toxic and harmless fire-resistant heat-insulating materials, and are equipped with fire-resistant hardware accessories to form a door with certain fire resistance.

The maximum size of single leaf of Class A, B, C steel fireproof doors is 1100x2300(mm), the maximum specification of double doors is 2100×2300(mm), the door leaf with fireproof glass opening size is T68: 300x800mm), T50: 230x760x30mm (Class A ), 230x760x26mm (Class B, C)
Note: Grade A, Grade B, and Grade C steel fire doors are different from the following two points:
The density of the filling material, the dry density is (400±40) kg/m3 for grade A, (360±36) kg/m3 for grade B, and (300±30) kg/m3 for grade C. The structure of steel fire doors is roughly the same as that of steel anti-theft doors, that is, side locks and lock forks are not allowed to be installed on steel fire doors. The inner filling material of the fire door should be a non-toxic and harmless high-temperature fire-resistant door core board, not honeycomb paper, rock wool, aluminum silicate and other filling materials. Single-leaf doors and child-mother doors can be equipped with fire-resistant door mirrors.
