The latest fire-resistant fence doors use newly designed hinges to replace the original door shafts and door frames. During the long-term use of the door shaft of the original fire door, due to the small number of welding parts and the low strength of the design itself, the door often deformed under the pressure of its own weight for a long time. The deformed fire door does not close tightly or even cannot be closed. The newly designed folding leaf after the renovation of the new fire-proof fence dual-purpose door is not only simple to process, but also strong and not easy to deform, which reduces the maintenance of the fire-proof door and is therefore suitable for long-term use. Secondly, after the folding is improved, the fire-proof door can be replaced The door is also quite easy to remove. You only need to pull out the cotter pin to remove it. It is also easy to install. Thirdly, due to the use of new folding leaves, the contact between the door leaf and the door frame changes from the original approximate line contact to a surface contact. The contact area is larger than that of the old fire door. After the fire door is closed, it is tighter and the air leakage is smaller.
