Exterior Use High Speed Roller Doors
Exterior use High Speed Doors are designed for outside doors of factory and warehouse, which will face wind pressure from outside. Such exterior rapid doors need be reinforced to withstand big wind.
Normally, if such doors are made from PVC fabric, it must be supported with metal wind bars at the middle. And the high speed door can be aluminum material, to get biggest wind resistance.
