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. high quality Class A fireproof window 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. Class A fireproof window Manufacturer The third problem is the pre rolling of the fire rolling shutter door. The fire rolling shutter door, especially the steel fire rolling shutter door, is relatively heavy, so a circle of pre rolling will be reserved on the reel to reduce the tension of the curtain weight on the screws. Prevent a curtain from cracking.

A brief talk on the problems encountered in the fire acceptance of Henan fire rolling shutter door 1. The curtain plate coating falls off and rusts, and the curtain plate has obvious pressure pits, concave convex, and penetrating holes. high quality Class A fireproof window The rolling shutter is a complete fire protection product. If the shutter has problems, it will directly affect the fire resistance limit index of the rolling shutter. 2. The guide rail is deformed and the curtain board is stuck or falls unevenly. The fireproof rolling shutter door generally moves along the guide rail. If the guide rail is twisted or broken, the rolling shutter door will not be able to move to the specified position, which will not achieve the effect of fire separation. 3. On the roller shutter, the lower limit fails or the limit line is wrongly connected. Class A fireproof window Manufacturer This often happens on the fire roller shutter of the atrium. Because the fire roller shutter of the atrium is sometimes installed outside the walkway of the upper floor, there is no floor under the roller shutter to close it, and a large gap is leaked, so the fire separation of the upper and lower floors cannot be reached.

The fireproof performance of Henan fireproof door is strong. With the development of the times, the fireproof door made of a kind of wood has played a role in fire prevention after processing. After the emergence of the fireproof door, it has gradually been applied to engineering and civil construction. high quality Class A fireproof window Next, the rolling shutter manufacturer will introduce the excellent fire performance of fire doors! In the high-rise and middle residential buildings, fire performance is very critical. As a related fire prevention function, it is better to have a better performance if the commercial house catches fire after installation. During the main use process, the advantages of performance and related fire prevention are also gradually emerging. As long as the fire protection performance is grasped, it is also critical in the safe passage. The key is to comprehensively grasp the advantages of such a fire door. Henan fire door is mandatory in the construction process for fire doors, because it is a kind of safety protection for the public. The quality of this door is very good, and from the appearance, the main thing is to grasp the relevant technology, to better grasp the advantages of this performance, can be used in many buildings, is to get permission, can be better reflected in this fire function. Because in the installation process, the installation is carried out by the relevant regular work installers. Class A fireproof window Manufacturer The operation process is also complex. The emergence of this kind of door industry is almost a unified brand everywhere.
