Application Pictures

Shutter door application is very extensive, mainly used in the field of fire, especially in today's high-rise buildings pull up, fire safety, fire prevention to prevention, is the first priority of fire armed police. Base is one of the necessary components of fire shutter door. Nowadays, the Shutter Bottom is hanging on the door body with a hollow square tube. There is a certain gap between the door and the guide rail, which leads to poor fire prevention effect. If the base is attached to the track, the clearance is reduced, but there is friction between the track and the noise is high and the loss is high. Because the base is hollow, there is a gap even if it is close to the track. Because the base hanging on the door body is not fixed, the base shaking causes the fire door to shake. The door body is easy to detach from the track when there is a large airflow in the fire site.
