Impact Resistance Hard Spiral Fast Doors

Product description:

It is a new metal industrial door that integrates wind resistance, environmental protection, high efficiency, sealing, energy saving and heat preservation. The opening speed can reach up to 2 meters per second.

The aluminum alloy turbine guide load-bearing track of the turbine hard fast door is developed by Hongfa automatic doors after many years of research. It ensures that the door curtain operates at a high height during the startup process. The rotational friction between the door curtain and the track effectively controls the noise. According to the on-site installation structure, it can be divided into : Turbine suction type, elliptical suction type, vertical lifting type, 90-degree standard turning lifting type or more orbital methods, the standard is turbine suction type.
