The spiral quick door panel is made of aluminum alloy with broken bridge and filled with polyurethane foaming agent.



The use of broken bridge aluminum, rather than profiles, is due to its better plasticity and insulation.『Anti pinch door panel』



The thickness standard is 40mm, 0.7mm behind the two sides of the board. The anti pinch design is more secure, and the height of the door board is 215mm.



Aluminum alloy is a kind of heat-conducting material, so no matter how thick the door panel is, it needs to adopt the design of broken bridge to separate the aluminum alloy on both sides of the door panel, improve the overall thermal resistance of the door panel and reduce the heat loss of the door panel.
