I. Drawing Review and Process Design

1. Drawing review: Carefully examine the steel structure construction drawings, and check whether the dimensioning, connection methods, technical requirements, etc. are clear and accurate. If there are any problems, communicate and solve them with the design unit in a timely manner.
2. Process Design: Based on the requirements of the drawings and the characteristics of the steel structure, a detailed processing technology plan is formulated, including determining the processing flow, selecting processing equipment and process equipment, formulating quality control measures, etc.

II. Material Procurement and Inspection

1. Material procurement: Purchase appropriate steel materials such as steel plates and section steel in accordance with design requirements to ensure that the specifications, models, and performance of the materials comply with standards and design requirements.
2. Material inspection: The purchased steel is subject to strict inspection, including appearance inspection, dimensional measurement, mechanical property tests, chemical composition analysis, etc. Only after passing the inspection can it be put into use.

III. Blanking and Cutting

1. Cutting: According to the construction drawings and process requirements, the steel is cut and blanched to the specified dimensions and shapes. Common blanking methods include flame cutting, plasma cutting, laser cutting, shearing, etc.
2. Bevel processing: For steel structural components that need to be welded, bevel processing is also required after cutting and blanking to ensure the welding quality. The bevel processing methods include mechanical processing, flame cutting, plasma cutting, etc.

IV. Forming Processing

Bending forming: Using bending equipment such as plate rolling machines and pipe benders, steel is bent into the required arc and shape. During the bending process, it is necessary to pay attention to controlling the bending radius and Angle to avoid defects such as cracks in the steel.
2. Stamping forming: For some steel structural components with complex shapes, stamping process can be adopted for forming. Through the action of the press and the die, steel is stamped into the required shape and size.
3. Correction: Correct the steel that has deformed during processing such as cutting, bending, and stamping to make it conform to the designed dimensions and shapes. The correction methods include mechanical correction, flame correction, etc.

V. Welding and Joining

Welding: Based on factors such as the material, thickness, and welding position of the steel structure, select appropriate welding methods and materials, such as manual arc welding, gas shielded welding, submerged arc welding, etc., to connect each component into a whole. During the welding process, the welding process parameters must be strictly controlled to ensure the welding quality and prevent welding defects.
2. Bolt connection: For some steel structural components connected by bolts, the processing of bolt holes and the installation of bolts should be carried out in accordance with the design requirements. The machining accuracy of the bolt holes should meet the standard requirements, and the tightening torque of the bolts should reach the specified value to ensure the reliability of the connection.

VI. Surface Treatment

Rust removal: Rust, oil stains, and oxide scale on the surface of steel structural components are removed by methods such as sandblasting, shot blasting, and acid washing to enhance the roughness and cleanliness of the steel surface, preparing for subsequent anti-corrosion treatments such as coating or hot-dip galvanizing.
2. Anti-corrosion treatment: According to the usage environment and design requirements of the steel structure, anti-corrosion treatment is carried out on the steel structure components after rust removal, such as painting, hot-dip galvanizing, and spraying anti-corrosion coatings, to extend the service life of the steel structure.

VII. Quality Inspection and Acceptance

1. Process inspection: During the processing of steel structural components, multiple quality inspections should be carried out, including checks on raw materials, cutting dimensions, forming accuracy, welding quality, surface treatment, etc., to promptly identify and correct quality issues during the processing.
2. Finished product acceptance: After the processing of steel structural components is completed, finished product acceptance should be carried out in accordance with the design requirements and relevant standards, including appearance inspection, dimensional deviation measurement, mechanical property tests, non-destructive testing of welds, etc. Only after passing the acceptance can they be put into use.

VIII. Marking and Packaging

Marking: On steel structural components, information such as product number, specification, model, production date, and inspection qualification mark should be marked to facilitate product identification, traceability, and management.
2. Packaging: Based on factors such as the shape, size, weight and transportation mode of the steel structural components, select an appropriate packaging method, such as using packaging steel straps, wooden crates, pallets, etc. for packaging to prevent damage during transportation and storage.
3. Shipment: Deliver products based on customer orders and contact the shipping company for vehicle dispatch and loading.
