The construction of steel structure engineering is usually divided into two stages: factory manufacturing and site installation. Steel structure engineering is mostly carried out in the workshop. Because of the quality of steel structure components processed and manufactured by our factory, it is very important for the site installation of steel structure engineering and the safety and stability of the whole structure. Therefore, steel structure manufacturing enterprises must have corresponding enterprise qualifications, production scale, technical capacity, machinery and equipment and advanced technology level

The general manufacturing processes of steel structure processing include lofting, cutting, assembling, submerged arc welding, drilling, assembling, rectifying, riveting, riveting, parts cutting, assembling, welding, inspection, rust-proof treatment, painting and acceptance of numbered parts. In the production of steel structure, according to the technological process of steel structure production, master the key process of quality control such as the processing control of key parts, the processing technology and measures of main parts, the processing equipment and process equipment used.
