Through many years of practice, we summarized the special technology of metal rotary shaft door: the frame of aluminum alloy rotary shaft door should be stainless steel, and the frame of door leaf should use stainless steel pipe or galvanized pipe. The door is filled with fireproof materials (which can be used for ahoy's thermal insulation and sound insulation as well as fire-proof function), and then the filler layer is sealed with 9mm thick aluminum alloy honeycomb plate. The panel is made of 6063t6 aluminum alloy plate. The door with this structure is suitable for both the North American cold region and the severe high temperature region in the Middle East. It can not only ensure the flatness of the door surface, but also ensure the impact resistance in the process of transportation and use. Then we can do all kinds of carving and inlay decoration on the door surface. The door styles made by this process are various and novel, the door surface is strong and durable, and the paint surface has strong adhesion. The main hardware uses the original imported German GAZE and Doma spring, multi-point anti-theft lock and all stainless steel customized handle. It is well received by customers in Europe, America, Australia and Israel.
