Safety is non-negotiable
Structures designed to Thai wind and seismic standards and checked by your licensed Thai engineer.

Customers · Government & public agencies
Markets, car parks, footbridges, depots, sports halls and community buildings that serve the public for decades. We design to Thai codes, fabricate in our certified factory and supply the contractor that builds your project, with full quality records for the handover file.
What you need

Public projects are judged over decades. A fresh market, car park, footbridge or sports hall must be safe, durable in the Thai climate and simple to maintain on a public budget.
Public works are built by the Thai contractor that wins the project. World Steel supports that contractor as the steel manufacturer and supplier: we design to Thai codes, fabricate under certified quality control and document every piece.

Designed and made in our own factory
We are not a broker or a steel trader. Our engineers design it, and our factory in Tay Ninh makes, inspects and ships every piece.
01World Steel structural engineers calculate to Thai and international codes and produce the Tekla 3D model, approval drawings and every shop drawing. Nothing is outsourced.
02Plates and sections cut by plasma, laser and CNC drilling lines straight from the model, with first-piece inspection before the batch runs.
03Submerged-arc welding lines and qualified welders make columns and rafters to ISO 3834-2 and EN 1090 EXC3.
04Dimensional checks, UT and MT weld testing and paint thickness readings, recorded piece by piece in the QC dossier you receive.
05Shot blasting and an ISO 12944 paint system chosen for inland, coastal or port sites, or intumescent fire protection up to R120.
06Every piece marked, bundled by erection zone and loaded so the first members your erector needs reach site first.
