Insulated Industrial Sectional Lift Door with CE Certificate
Sectional doors designed for factory and hangar applications, featuring easy operation, wind resistance, and thermal insulation properties.
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, making them suitable for installation in virtually any conditions.
Insulated Sectional Doors Construction
Industrial sectional doors feature double-layer sandwich hot-dip galvanized steel panels with polyurethane surface processing. The 40mm thick core contains polyurethane insulation material. The door body includes box-shaped edge banding with connecting hinges for embedded track installation. Comprehensive sealing systems using spherical vinyl resin strips prevent wind, rain, and penetration along the width and height of the door.
