Wind-Resistant Sectional Rolling Shutter Door
Product Description
Insulated Sectional Garage Door for Cold Storage
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 feature wide panels that can be customized with windows in select sections and steel in others. When retracted, these doors roll up and lie flat against the ceiling. The primary advantage is their adaptability to virtually any installation conditions.
Insulated Sectional Doors Construction
Our industrial sectional doors feature double-layer sandwich hot-dip galvanized steel panels with polyurethane surface processing. The core consists of polyurethane insulation with a thickness of 40mm. The door body includes box-shaped edge banding with connecting hinges mounted on the banding, enabling embedded track installation.
