Process of push pull industrial door

Briefly describe the manufacturing process of push-pull industrial door

1. The skeleton of industrial door is made of cold rolled square steel pipe, Angle steel, flat steel and other profiles. The general door-type door panel is made of 1.2mm thick pressed steel plate, and the insulation door-type door sector is made of metal insulation sandwich plate.
 2. The industrial door skeleton is made of arc welding, welding rod, and continuous welding except where indicated. There shall be no welding defects such as non-melting, non-penetration, porosity, crack burning through, etc. 
3. Industrial door fan skeleton profile should be straightened before cutting, and welding should be carried out after lofting on the flat site or working table. After welding, the door should be straightened and shall not exceed the allowable size error. 
4. Industrial door frame processing and production after inspection and then laying the panel. General door type door sector steel plate can be used spot welding, riveting or screw connection, the joint between the steel plate should be overlapped after internal and external intermittent spot welding or riveting. After processing should be coated with anti-rust paint and then coated with top paint, insulation door skeleton welding coated with anti-rust paint. The metal adiabatic sandwich plate is machined and cut according to the skeleton size, and the sandwich plate is embedded in the skeleton of the door fan, and the integrated drilling riveting or screw connection. 
5. The sealing rubber strip of the industrial door is fixed on the door with screws and layering strips.
