　　Steel structures, composed primarily of steel materials, are one of the main types of building structures. These structures consist mainly of steel beams, columns, trusses, and other components made from steel sections and plates. Rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are employed. Components or parts are typically connected using welds, bolts, or rivets. Due to their relatively light weight and ease of construction, steel structures are widely used in large factories, stadiums, super high-rises, and other fields. Steel structures are prone to rust, so they generally require rust removal, galvanizing, or coating, and regular maintenance. Here, the steel structure fabrication factory introduces the manufacturing process of these products.

　　The design drawings provided by the architectural design institute cannot be directly used for fabricating steel structures. Instead, processing factors such as tolerance fitting, machining allowance, and welding control must be considered. Based on the original design drawings, a processing and fabrication drawing is created. This drawing serves as a bridge between the designer's and constructor's intentions. It functions as a guide for manufacturing, detailing actual dimensions, marking, cutting, bevel processing, drilling, bending, assembling, welding, coating, product inspection, stacking, shipping, and other operations. Additionally, it acts as a checklist for high-level management.

　　Analysis of Construction Conditions Before Processing and Fabrication

　　When creating or reviewing the processing and fabrication drawing, it is crucial to analyze and study the construction conditions or level of difficulty simultaneously. Special attention must be given to areas with challenging welding requirements, the use of high-strength bolts and tightening tools, and maintaining proper welding angles for electrodes in confined spaces.

　　Steel Tape Measures

　　In steel structure fabrication projects, any one of the first-grade products, such as leather tapes, wide steel tape measures, or convex steel tape measures, can be used. It is essential to ensure that the tape measures used in the factory are of the same type as those used on-site, meaning all trades use "the same ruler." If this is difficult, the mutual difference between 10-meter tapes should be controlled within 0.5mm.

　　Operators should undergo training and assessment before taking their posts, and special trades should undergo qualification confirmation. Technical disclosures for various processes should be fully prepared.

　　The above is the relevant introduction to the manufacturing process at the steel structure fabrication factory. We hope you have gained a better understanding. Welcome to inquire.
