Double aluminum alloy shutter door, is made of double aluminum alloy shutter door, compared with the traditional galvanized iron shutter door in performance and function are greatly improved. Double-layer aluminum alloy rolling shutter doors are mostly used in medium and high-grade factory warehouse doors, especially where the anti-theft and heat preservation effect of the warehouse is better. Compared with the fast door, the fast door has the function of heat preservation and heat insulation, and the switching speed is very fast. PVC curtain is made of flame retardant material, which has certain fire resistance and is used for dust-free workshop and other places with high environmental requirements.
Double aluminum alloy shutter door with high strength and high toughness corrosion resistance of aluminum alloy extrusion molding, durable, safe and reliable. The appearance is specially treated to make it more durable and not easy to rust. The fast door adopts imported industrial base cloth as the door curtain, and the drive system adopts servo motor and servo electric control box to control, which can reach the speed adjustment of 0.6 m/s to 2 m/s.
The main application difference of double aluminum alloy rolling shutter door and fast door is that the switching speed of fast door is faster than that of aluminum alloy rolling shutter door, but the anti-theft performance of aluminum alloy rolling shutter door is much stronger than that of fast door. Therefore, customers can choose according to the needs of their own application sites. If the application sites have multiple requirements, two doors can be installed at the same time. Similar to the need for fire prevention and fast doors, they need to install fire doors and fast doors, so that they can meet multiple requirements at the same time.
