Description

Industrial sectional door is made for clients who need firm, good heat-resisting function and space saving outer wall doors. Sliding upward till under the ceiling when start up, the door occupies little room. Therefore, the room door can be fully opened. The high quality sandwiched door panel has excellent insulating performance. Combining a double-skinned bottom section in steel with a glazing frame in anodized aluminum has made for a practice-proven, highly robust door leaf construction. Adding double glazing provides the positive effect of thermal insulation. The thick insulating polyurethane rigid foam produces an extremely high thermal insulation value.
