Product Description
Industrial Sectional Doors for Factories and Hangars
Our sectional rolling shutter doors are engineered for industrial applications, offering easy operation, wind resistance, and superior heat insulation properties.
What Are Sectional Rolling Shutter Doors?
Sectional steel doors feature wide panels that can be customized with windows or solid steel sections. When retracted, these doors roll up compactly against the ceiling, making them suitable for virtually any installation condition.
Insulated Sectional Door Construction
Our industrial sectional doors feature double-layer sandwich construction with hot-dip galvanized steel plates and polyurethane surface processing. The 40mm thick core contains polyurethane insulation material for excellent thermal performance.
The door body includes box-shaped edge banding with connecting hinges for embedded track installation. Comprehensive sealing systems using spherical vinyl resin strips along the width and height prevent wind, rain, and air penetration. The balanced torsion spring system ensures smooth operation even without motor power.
