Our 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 aluminum and plane thrust bearing, reduced the friction caused by resistance. Frame adopts the professional aluminum 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.
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.
Hanging wheels are made of sealed bearings and PA66 nylon, four wheels can increase the strength and make the door move smoothly.
