GRP technique introduced from Germany sound isolation and heat insulating fire rated and lightweight service life min 25years

Fiberglass reinforced sectional overhead industrial 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 GFK as main material. GFK is light in weight, strong in light transmittance, wonderful in mechanical strength and it is ultraviolet, sound and heat proof. Meanwhile GFK has good performance in weather resistance, fire performance comes up to DIN4102 level B2. 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 operated to ensure safety. Sectional door is ideally suited to plant, warehouse, fire protection and garage door.
