overhead sectional fiberglass access doors

New generation of industrial door; Non-hinged type connection; Spring balance system.

Fiberglass overhead sectional door:

Integrated with the technology introduced from Germany, our sectional door becomes new generation of industrial door. The modern but reasonable design and the elegant appearance make it to be unique. The surface of shutter uses orange-figured aluminium plate which is treated by painting to become colorful and corrosion-proof. The shutter is filled with rigid polyurethane and fixed by sealing sleeve. Aluminium rotation axis, non-hinged type, is used to connect shutters. Refer to spring balance principle, through mini-watt drive device, shutters move along vertical track smoothly with little noise. Meanwhile it is equipped with safety feature. During the process of close, any hit or touch from obstacle will stop the moving and start to back to full-open. If any accident, it can be adjusted to manual operating to ensure safety. Sectional door is ideally suited to plant, warehouse, fire protection and garage door.
