Background technique

The rolling shutter door (rolling gate) is connected in series with multi-joint movable door pieces. In a fixed slideway, the upper and lower doors are rotated around the scroll above the door. Roller blinds are usually widely used in shops.

Due to the large height and width of the rolling shutter door in the prior art, the planar bending resistance of the rolling shutter is also weak, and the surrounding frames are not enough to provide sufficient wind resistance for the rolling shutter door. When encountering strong winds, the rolling shutter door will bend and deform, seriously Sometimes a local gap is formed, and even the shutter door is damaged.
