Pattern making: This involves verifying the installation dimensions and spacing of the drawings, producing 1:1 scale patterns for key nodes, checking the dimensions of each part, and creating templates and gauges as references for material cutting, bending, milling, planing, and hole making processes.
Material Marking: This includes checking and verifying materials, marking the cutting, milling, planing, and drilling positions on the material, punching holes, and labeling part numbers. Attention should be given to the following issues: Cut according to the bill of materials and sample to save materials as much as possible; it should facilitate cutting and ensure part quality; when specifications are in place, materials should be taken according to the regulations.

Cutting and Material Preparation: Includes methods using high-temperature heat sources such as oxygen cutting (gas cutting) and plasma cutting, as well as mechanical methods like machine cutting, stamping blanking, and sawing.
Straightening and Correction: Including mechanical correction of profile straightening machines and flame correction, etc.
Edge and End Processing: Methods include beveling, planing, milling, carbon arc gas cutting, semi-automatic and automatic gas cutting machines, beveling machine processing, etc.
Roundness: Processing can be done using symmetrical three-axis rounding machines, asymmetrical three-axis rounding machines, and four-axis rounding machines, among other mechanical options.
Bending: Depending on the specifications of the material, machinery such as steel roller bending machines, bending machines, and press brakes can be used for processing. When hot forming is adopted, temperature control is crucial to meet the specified requirements.
Hole Making: Includes rivet holes, standard bolt holes, high-strength bolt holes, and anchor bolt holes, etc. Steel Structure Manufacturing Construction Techniques Application Scope: Suitable for the processing and manufacturing processes of building steel structures, including the selection of processes, pattern making, material marking, cutting, straightening, shaping, edge processing, pipe and sphere processing, hole making, friction surface processing, end processing, assembly of components, round tube component processing, and pre-assembly of steel components.
Regulations for Steel Structure Construction:
The spacing between the flange and web joint seams of the steel sections should be greater than 200mm. The length of the flange joint should not be less than twice the width of the plate; the width of the web joint should not be less than 300mm, and the length should not be less than 600mm.
Ensure welding quality by assembling and welding reinforcing plates, connecting plates, shims, and cantilevers (beams) on the ground steel platform according to the construction drawings' dimensions as much as possible.
3. Reinforce with steel locally or along the full length of components, connecting them into an integrated structure to share forces; add auxiliary supports, adjust load distribution, reduce internal forces, and force displacement of the superstatic structure supports to lower stress peaks.
