Due to the size of the steel plate size constraints, single door in the case of no joints in the case of the door width can be made size ≤ 1200mm. C-class C-class fire doors filled with different internal thermal insulation coefficient of non-combustible materials from the processing, B / C grade gate thickness of less than 45mm. The door frame structure has two kinds of cross section. Shaped large cross section is mainly designed for box-style wall structure. With high noise, air tightness requirements of the fire doors and more use of four sides of the box (the next threshold with the mouth and add a sealed slot, the tank filled with chloroprene rubber.
