Automatic welding of a built-up steel member in the World Steel factory

One plant, one quality system, every market

The World Steel factory at Hai Son Industrial Park, Duc Hoa, Tay Ninh Province, close to the container ports of Ho Chi Minh City, is where our structural steel and pre-engineered buildings are made – from the largest built-up members to the smallest fittings, including oversize and special structures.

Fabrication runs under quality and welding management systems recognised in our export markets: AS/NZS 5131 CC3 for Australia and New Zealand, EN 1090-2 EXC3 with CE marking for Europe, ISO 3834-2 for welding quality, IAS AC472 for the United States and BC1 for Singapore. World Steel was the first company in Asia accredited under IAS AC472.

תהליך

Our 12-step production process

Each step is carried out by trained workers, supported by production supervisors and checked by QC before the member moves on.

01
Material receiving & inspection

Steel plate arrives at the factory and is checked against the purchase order and the mill certificates – grade, thickness, dimensions, surface condition and heat number – before it is released to production.

02
Laser cutting

Web and flange plates are cut by laser, and end plates, stiffeners and connection plates are cut and their holes made by laser in the same operation – accurate parts with clean edges and precise hole positions.

בקרת ייצור

Three roles at every step

No step in our factory is finished just because the work is done. Every step is performed by a worker, supported by a production supervisor and checked by a QC inspector – and only QC releases the member to the next step.

If a check fails, the member goes back for repair and re-inspection. The result is quality built in step by step, not inspected in at the end – and a complete record for every member.

WorkerPerforms the step to the shop drawings and welding procedures.

Production supervisorSupports the team, sets up the line, resolves issues and keeps the schedule.

QC inspectorInspects, records and releases – or holds the member for correction.

איכות

Quality you can trace

Quality at World Steel is a chain of recorded checks from plate to dispatch – material traceability by heat number, first-piece checks in cutting, welding records, a dimensional hold point, visual inspection and NDT, coating thickness and packing control.

All records come together in the quality dossier delivered with the project, and our certifications are maintained by regular surveillance audits by independent bodies – see Europe, Australia and US standards.

לוגיסטיקה

From our gate to your site

Every member carries its package code, so it can be found in the packing list, on the container plan and on site. Bundles are protected and loaded for 20 ft and 40 ft containers, flat racks or break-bulk, with oversize members planned with the forwarder.

The plant is a short road trip from the container ports of Ho Chi Minh City – see export supply & logistics and our market guides.
