Features of steel-wood (solid wood edge-sealing) heat-insulating fireproof doors:
The frame of the steel-wood (solid wood edge-sealing) heat-insulating fireproof door is made of steel plate, the frame of the door leaf is made of fire-retardant treated wood, lined with steel plate, the door panel is made of man-made fiberboard with veneer finish, and the inner filling material of the door leaf is non-toxic and non-toxic to humans. Fire-resistant and heat-insulating materials, combined with fire-resistant hardware accessories, have a certain fire-resistant door.

Note: Class A and Class B steel and wood fire doors are different from:
1. The density of the filling material (fire door core board) of Grade B steel wood (solid wood edge sealing) heat insulation fire door is (360±36) kg/m³;
2. The maximum processing size and cover type of steel-wood (solid wood edge-sealing) heat-insulating fireproof doors:
2.1 Single door 1100mmx2300mm, the door leaf can have a pattern;
2.2 The double door is 1800mmx2300mm, and the door leaf can be patterned;
