Product Description
0.4mm Galvanized Steel Security Automatic Garage Door
Sectional Door for Factory and Hangar Applications - Easy Operation, Wind-Resistant and Heat-Insulating
What is a Sectional Rolling Shutter Door?
Sectional roller shutter doors consist of wide panels that can be customized with windows or steel sections. When retracted, these doors roll up and lie flat against the ceiling. The primary advantage is their adaptability to virtually any installation condition.
Insulated Sectional Doors
Our industrial sectional doors feature double-layer sandwich hot-dip galvanized steel panels with polyurethane surface processing. The core contains polyurethane insulation with a 40mm thickness. The door body includes box-shaped edge banding with connecting hinges for embedded track installation. Comprehensive sealing systems prevent wind, rain, and penetration, while the torsion spring balance system ensures smooth operation even without motor power.
