Automatic PU Insulated Warehouse Sliding Industrial Folding Door

Automatic PU Insulated Warehouse Sliding Industrial Folding Door- Product overviewOur automatic folding door features the automatic operation and rapid opening from closure to full opening, it also can be manual operated in case of power failure easily. Our automatic folding door will bring you the fastest running speed and security at any time. The European standard production process has been used in folding doors, and the frame is invisible. Also, coarctation design is used between surface panel and frame, without welding.The high density polyurethane foam whose density exceeds 50kg/m3 is used for the whole door. It can not only enhance the tightness between surface and implicit frame, but also beautify the appearance to a large extent.The connecting hinge adopts casting aluminium and plane thrust bearing, reduced the friction caused by resistance. Frame adopts the professional aluminium alloy strengthening design to make installation much more convenient, solid and improve the degree of beauty. In the assembly, we use embedded pull rivet nut, prevent the screw loose.- Product application A. Rapid fireproof folding doorHigh speed folding door for fireproof, high-speed opening and normal speed opening optional. The fastest opening speed can be 90° at 7 seconds, normal speed can reach 90° between 16-26 seconds (differ from door width).B. Commercial folding doorWith modern and futurist appearance, our commerical folding door is a flexible door, U value is 1.1W/M2°K, noise in laboratory can be reduced in 55 dB, which is suitable for disabled people access.C. Subway/High-speed train folding doorThickness of door panel is 57mm; Surface material uses aluminium zinc plate or aluminium plate, the plate thickness is 0.6mm-1.2mm; Open mode: manual, automatic, infrared ray and so on; Foaming density exceeds 59KG/m3; Can reserve high voltage wire insulation; Material of frame: Steel or aluminium; Width adaption: Steel≤5060mm, aluminium≤6000mm- Product featuresHidden frame design: The frame of door is made of cold-rolled galvanized steel, and designed with U-shape concave and convex grooves molded by special rolling machine. It is covered with 0.6mm to 1.2mm of aluminium plating zinc plate or aluminium alloy plates on both sides, and foamed overall.It has higher strength, the thickness (57mm & 77mm) is optional.It has multi-section structure doors, when the door doesn't need to be completely opened, a part of the door will open to reduce the open & close time, and heat loss.The top of the door is sealed with high density double-layer brush. The door frames and each door panel are sealed with EPDM.The top rail is made by 4mm thickness steel plates, and mounted directly on the side wall or fixed on the eaves. The thickness should not be less than 4mm.The bottom water deflector is made of 2mm thickness aluminium alloy guide slots with a small angle of waterproof slope (or more special design configuration). The bottom water deflector is configured as standard when there are more than 3 sections / panels in a single door, and it is optional when less than 2 sections / panels.Door and hinge are connected by embedded pull rivet nuts, the hardware for connecting the door is embedded rivet nuts.The top rail is made of 50x50x3mm steel or 5mm thickness aluminium alloy, the top rail with one-sided four flods is made of 4mm galvanized steel molding rails.Hanging wheels are made of sealed bearings and PA66 nylon, four wheels can increase the strength and make the door move smoothly.Configuration range: Standard width of single-section can be 650mm to 1200mm, the maximum width of single section is 1500mm, the thickness of the door panel is 57mm or 77mm optional. For the 77mm panel, it is appropriate door height of 8000mm, and the maximum height of a single door panel is 13000mm; For the 57mm panel, it is appropriate door height less than 8000mm.- Manual & Auto folding options   - Our ProfessionalismOur team works in this industry with many years' experience, from the design, manufacture, package, delivery, installation and commissioning, maintenance after-sale service, we provide all-sided supports for our customers at every link, particularly, our technicans can design the suitable door based on the customers' practical demand to save the cost, and provide our customers the effective training to help them operate and maintain the doors properly.- PackageQualified plywood for LCL; and Qualified carton or pallet for FLC, however, we are able to provide the package according to your specified requirements.- Service scope1.
