Compared with the traditional door panel, the industrial door panel with large back reinforcement is equipped with reinforced back reinforcement, which has greater strength and better bending resistance. It is suitable for large hole installation, ensuring the wind resistance and compression resistance of the whole door can reach 8-10 wind pressure.

The interior is filled with polyurethane material, providing excellent heat insulation, sound insulation, and heat preservation. It is widely used in various industrial plants and large lifting doors.
