Bundling
Members are bundled by type and length, with bundle weights and lifting points recorded so the container plan and site crane capacity match the load.

Standard route
How a project like this moves through the factory
The sequence below is the standard fabrication route. The specific inspection scope and standards are confirmed for each project.
- 01
Raw material receiving
Material identity, dimensions and documentation are checked against confirmed project requirements.
- 02
Cutting
Approved member information guides plate and section preparation.
- 03
Assembly
Components are fitted and checked against approved fabrication information.
- 04
Welding
Welding requirements and inspection scope follow confirmed project documentation.
- 05
Straightening
Member geometry is checked and corrected within the confirmed acceptance criteria.
- 06
Shot blasting
Surface preparation requirements must be confirmed before processing.
- 07
Painting
Coating system, color, dry-film requirements and repair method require project confirmation.
- 08
Packing and loading
Marks, bundles, protection and loading sequence are reviewed before shipment release.
Quality control
Checkpoints recorded before release
These are the control points applied before a member or bundle is released.
- 01
Material receiving check
Steel grade, heat number and mill test certificates are checked against the approved material list before any plate or section is cut.
- 02
Cutting and drilling check
Component length, hole diameter, hole group position and edge preparation are measured against the approved shop drawings.
- 03
Assembly and welding check
Fit-up, root gap, camber and weld leg size are checked before welding. Weld procedures and welder qualification follow the standard specified for the project.
- 04
Dimensional inspection
Overall length, squareness, member straightness, connection locations and hole groups are measured after welding and before surface treatment.
- 05
Surface treatment check
Shot-blast grade, coating dry film thickness or galvanizing coverage are inspected and recorded against the coating specification.
- 06
Packing inspection
Bundle contents, piece marks, protection of connection faces and the loose-part list are checked against the packing list before loading.
Packing and delivery
How the shipment side is prepared
Packing, marking and loading preparation follow the same sequence for every order.
Marking
Every bundle carries a piece mark, bundle number and project reference that match the packing list and the erection drawings.
Protection
Connection faces, machined surfaces, coated edges and insulated panels are protected for sea freight. Loose parts are packed and itemised separately.
Container Loading
Loading plans use 40HQ, 40OT or 20GP containers, with the sequence set by component weight, length and the unloading order at site.
