Our factory · Hai Son Industrial Park, Tay Ninh, Vietnam
The factory where your steel building is made
A 20,000 m² steel structure factory, owned and run by World Steel since 2016. Cutting, welding, shot blasting, painting and inspection under one roof: 2,500 T a month, certified to ISO 3834-2, EN 1090 EXC3 and IAS AC472, exporting to Thailand since 2018.
Factory overview
One factory, one quality system, every Thai project
The World Steel factory stands in Hai Son Industrial Park (Phase 3+4), Duc Hoa, Tay Ninh province, 60 minutes by road from our head office in Ho Chi Minh City. Every steel frame, purlin and fire-protected member we deliver to Thailand is cut, welded, blasted, painted, inspected and packed here.
Because the plant is ours, we decide the fabrication slot, control the quality at every stage and confirm the shipping date. You deal directly with the company that makes your steel.
- Fabrication to ISO 3834-2 and EN 1090 EXC3
- Independent QA/QC department, reporting to quality management
- Raw steel from Europe, Japan, Korea and Taiwan, traceable to mill certificates
- Intumescent fire protection up to R120, applied in the factory
- Packed in erection order for CIF or DDP delivery to Thailand
Close to Ho Chi Minh City and the deep-sea port
Visitors from Thailand reach the factory the same day they land. Your steel leaves for Thailand from Cai Mep, Vietnam’s deep-sea gateway.

Inside the factory
Four zones, from raw plate to packed container
Steel moves through the factory in one direction, and every stage is inspected by QC before the next one starts.
-
Zone 1 / 4
Material receiving & storage
Plates and sections are checked against their mill certificates, identified by heat number and stored by grade before they are released to production.
- Mill certificate check, EN 10204 3.1 on request
- Heat-number traceability
- QC stage 1: incoming material inspection
-
Zone 2 / 4
Cutting, fit-up & welding
Plates are cut and drilled on CNC machines, then built-up beams and columns are fitted, welded on the automated and gantry welding lines and straightened.
- CNC plasma, gas and laser cutting
- CNC drilling and punching
- Automated and gantry beam welding
- Visual weld inspection and NDT (UT, MT)
-
Zone 3 / 4
Shot blasting & painting
Members are shot blasted to Sa 2½ and painted to the specified ISO 12944 system. Intumescent fire protection is applied here too, where film thickness can be controlled and recorded.
- Shot blasting to Sa 2½
- Paint systems to ISO 12944
- Intumescent coating up to R120
- Dry film thickness records
-
Zone 4 / 4
Marking, packing & container loading
Every member is marked with its component code, bundled in erection order and loaded into containers for the port.
- Component coding system
- Packing lists by erection sequence
- Container loading for Thailand

HOLDtag + NCRQuality
Inspected at every stage before it moves on
Our QA/QC department inspects every stage of fabrication. If a defect appears, QC tags the item “Hold” and opens a non-conformance report (NCR); it moves on only when it passes.
