Product Description

Automatic Sectional Garage Door for Industrial Facilities

Insulated & Secure sectional doors designed for factory and hangar applications. Easy to operate, 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, making them suitable for almost any installation condition.

Insulated Sectional Doors Construction

Our 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 system includes top, bottom, and lateral sealing strips made of spherical vinyl resin to prevent wind, rain, and penetration. The balance system consists of torsion spring, reel, steel shaft, and locking flange for smooth operation.
