For export steel structure projects, clients focus not only on price but also on process control, quality assurance, international code compliance, and delivery reliability. A standardized and traceable manufacturing and export process is essential for successful project execution and long-term cooperation.
Below is a complete overview of the steel structure fabrication and export process based on international project requirements.
1. Technical Review and Shop Drawing Approval
The process starts with reviewing:
- Structural and architectural drawings
- Design codes (AISC / ASTM / EN / ISO)
- Material, corrosion protection, and fireproofing requirements
- Packing and shipping specifications
Detailed shop drawings are prepared and submitted for client or third-party approval.
2. Raw Material Procurement and Inspection
Steel materials are sourced according to project standards, such as:
- ASTM A36 / A572 / A992
- EN S275 / S355
Incoming materials are checked for:
- Mill test certificates (MTC)
- Chemical and mechanical properties
- Dimensions and surface quality
Full traceability is ensured.
3. Cutting and Material Processing
CNC-controlled equipment is used, including:
- Laser cutting
- Plasma cutting
- CNC flame cutting
Ensuring high dimensional accuracy and clean edges.
4. Forming, Assembly, and Welding
Fabrication follows approved shop drawings:
- Component assembly
- Automatic or semi-automatic welding
Welding complies with:
- WPS / PQR
- AWS D1.1 / ISO 3834
Critical welds undergo NDT testing (UT, MT, PT).
5. Straightening, Finishing, and Inspection
After welding:
- Components are straightened
- Welds are ground
- Dimensional and visual inspections are conducted
6. Surface Treatment and Corrosion Protection
Based on environmental requirements:
- Hot-dip galvanizing (ASTM A123)
- Heavy-duty coating systems (ISO 12944 / SSPC)
All parameters are recorded, including surface prep and DFT.
7. Trial Assembly and Final Inspection
Key structures are pre-assembled in the factory to verify:
- Dimensions
- Connection accuracy
Third-party inspections (SGS, BV, TÜV) are often included.
8. Packing, Marking, and Export Shipping
Export packing includes:
- Moisture and impact protection
- Component marking and packing lists
- Containerized or break-bulk shipping
9. Documentation and Technical Support
Final delivery includes:
- As-built drawings
- Material and inspection reports
- Coating and welding records
- Installation guidance and after-sales support
