Cold High Speed ​​Door is a line of fast rolling doors with PVC recovery screen to prevent deep freezers. The curtains are specially constructed with 2 layers of insulating PVC synthetic fiber fabric and a 5mm layer of insulating foam in the middle that provides good insulation to help limit heat loss and effectively save energy.
Cold High Speed ​​Door uses a zipper to connect the screen and door frame. When a collision with a person or vehicle occurs, the operating door immediately stops and returns to its original state, suitable for areas with high traffic density much.
