the leader and environmentally aware and energy settling, where does h f g series high speed spiral door, everything is developed on the basis of science and technology. quality is much more newer and newer, high speeds. viral door is representative of the most advanced technology, more efficiency and energy. qinghai lave, as intelligent equipment technology company limited, has been focused of researching and manufacturing high speed industrial doors since two thousand four. then h f g series high speed spiral door is the best choice because of its structure, designing and safety, protection and energy saving. and the best choice for the customers, the high speeds spiral door is designed of double spiral guide rails on the law of our committee spiral to make the door running stable and quiet without any friction and prolong the lifespan of the door. next opening speed could be up to five point eight minimum per second and could be different hosting ways to use the space very effectively. ray fast stores could provide best solution to different cuts, all of the key components are made of super material from the advanced equipment machines. h f g series product could be running two hundred seventy thousand without any faults, and when resistance could be up to gb, the thickness of the door leads could be forty three millimeters, sixteen millimeters, eighty millimeters when the door late. this designs, specifically a made of aluminum alloy filled with pu material. hindi slammed both sides of the door, lives and fields between the door. thermal insulation performance could be gb seven grade air installation performance could be gb free at the same time. the protection, designing and self repairs structure could show better performance. it means when the door will be out of the guide rail, then be self prepared on the opening process without anybody with less maintenance fees, quite better for the users and vehicles. and h f g series products could be controlled ways of button, radar, induction loops, r f remote controller, whole switch and many other control, even if any accident has happened, the user could open the door easily by manual. by the balance system on the door design to meet the need of the users, better design is better, safer and very widely used in field of automobiles. so electronics, logistics, realistic firefighting and many other areas spend that solution to isolated workshop and sort of and other registered channel and so on. quality brand and vast service rafat stores is on the way all times wave after is believing in innovation unless service forever, we are ready for making our energy saving chinese dream come through. changed out those facts, intelligent equipment technology company limited.
