As is well known, fire doors are used for fire protection, and they are mainly used in large shopping malls, supermarkets, and other areas with special fire protection requirements. When the manufacturer orders this fireproof rolling shutter door for installation, it is inevitable to encounter various problems that hinder the progress of installation. Today, as a strong manufacturer and a professional installation technical team, the rolling gate manufacturer will share with you the most common problems in the installation of fireproof doors based on years of installation experience.

1、 The strength issue of the transmission device for fire resistant rolling shutter doors: The strength issue of the rolling shutter shaft is also an important parameter of the rolling shutter door. Currently, there are many products with unqualified strength, which seriously affects the use of fire resistant rolling shutter doors. The structure of the rolling shutter shaft mainly refers to the depth of the rolling shutter shaft and the two end shaft heads inserted into the steel pipe, and the depth of the shaft head inserted into the structure should be about 110 times the length of the shaft, and there should be two flanges and sufficient welding seams.

2、 The depth issue of the guide rail: If the depth of the guide rail is not sufficient and the structure and materials are not used properly, in case of a fire, the door curtain can easily detach from the guide rail and cannot play a fire prevention role.

3、 Pre rolling problem of fire resistant rolling shutter doors: Fire resistant rolling shutter doors, especially steel rolling shutter doors, are relatively heavy, so a circle of pre rolling will be reserved on the roller to reduce the tension of the curtain weight on the screws. Prevent the first curtain panel from cracking.

4、 Problems with fire prevention electric control boxes and smoke and temperature sensing: National standard regulations on fire temperature control and door closing. Within 2 meters of the fireproof rolling shutter door, when a fire occurs. Power interruption. When there is no one on site to operate, there should be a fire temperature fuse control door closing device, which is particularly important for densely populated areas.

I hope everyone takes the above issues seriously. How to install fireproof doors and how to ensure their firmness is also a very important issue.
