Sectional doors designed for factory and hangar applications, featuring easy operation, wind resistance, and thermal insulation properties.
Sectional Rolling Shutter Door Overview
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 almost any installation condition.
Insulated Sectional Door 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, along with comprehensive sealing systems for weather protection.
