Prefabricated steel transportation system

Introduction

The production process of steel structure transportation system products usually includes design, raw material procurement, processing and manufacturing, quality inspection, surface treatment, transportation, and installation. The following is a detailed breakdown of the process:

1. Design phase

Requirement analysis: Clarify customer requirements, determine the purpose of the system (such as logistics transportation, storage equipment), load capacity, and operating environment.

Structural design: Use CAD/3D modeling software (such as SolidWorks, Tekla) to design steel structures, including trusses, brackets, tracks, and other components.

Mechanical calculation: Verify structural strength, stiffness, and stability through finite element analysis (FEA).

Drawing output: Generate manufacturing drawings, assembly drawings, and bill of materials (BOM).

2. Raw material procurement

Steel selection: Purchase steel sections (H-beams, I-beams), steel plates, steel pipes, etc. according to design requirements. Common materials include Q235B/Q355B (Chinese standard) or ASTM A36/A572 (international standard).

Auxiliary materials: bolts, welding rods, anti-corrosion coatings, etc.

3. Processing and manufacturing

(1) Cutting

Use flame cutting, laser cutting, or sawing machines to cut steel to ensure dimensional accuracy.

Remove burrs on the cutting edge and polish.

(2) Forming

Bending/Rolling: Cold bending or hot bending of steel plates (such as conveyor belt rollers).

Drilling/milling: machining bolt holes or connection points.

(3) Welding and assembly

Component welding: submerged arc welding, CO ₂ gas shielded welding, etc. are used to weld main structures such as trusses and brackets.

Pre assembly: Conduct trial assembly in the factory to check fit and dimensions.

(4) Mechanical processing

Precision machining of high tolerance components (such as rail joints) to ensure flatness and dimensional accuracy.
