Although the fireproof door is also made of steel, the door plate is filled with fireproof materials, and the thickness of the door plate also has different requirements. The steel door is an ordinary steel door. It also has a certain anti-theft function, but its anti prying performance is relatively poor. This type is common in street processing plants. Only Shanghai and Chengdu have local standards for fire and burglar proof doors, and those in other places can only be called fire entry doors, that is, fire doors that reach the standard of fire rated A or B, and (filled with fire door cores) Class A and B standards are generally divided by fire resistance time. At the same time, it meets the anti prying requirements in the following aspects: the door frame is 1.5 thick, and the steel plates on the front and back of the door leaf are 0.8 thick. The lock has the anti prying function, that is, the lock body has both an oblique locking tongue and a square locking tongue. It has the function of quick opening.

The installation of Henan fire rolling shutter door is prone to some problems. One problem is the strength of the transmission device of the fire rolling shutter door. The strength of the roller shutter shaft is also an important parameter of the roller shutter door. At present, there are many unqualified products with this strength, The structure of the roller shutter shaft that seriously affects the use of the fire shutter door mainly refers to the depth of the roller shutter shaft and the shaft heads at both ends plugged into the steel pipe and the depth of the structural shaft head plugged into the steel pipe should be about 110 of the shaft length, and there should be two flanges and enough welds. supply Refuge bay door The second problem is the depth of the guide rail. If the depth of the guide rail is not enough and the structure and materials are improper, once encountering a fire, the door curtain is easy to detach from the guide rail and cannot play a role in fire prevention.
