Customers · Design & build and general contractors
We design, fabricate and ship the steel structure package. Your team keeps the client, the site and the construction. You win more tenders with a firm steel price, and you build on schedule with steel that fits the first time.
What you need

As a Thai general contractor or design-build firm, you carry the risk of the whole project. The steel structure is often the biggest single package, and the one that decides whether the programme holds, whether the job is a factory building, a warehouse, a car park or an aircraft hangar.
You need a supplier that prices your tender quickly, designs and details the steel so your engineer only has to review it, and delivers bundles your erection crew can put up without cutting or re-drilling. And you need to know that supplier will never bid against you for your own client.

How we work with you

Drawings, BOQ or a short brief with size, use and location.

After award: calculations, approval drawings and the 3D model for review.
Made and inspected in our factory. Your client can visit or audit online.
Bundles in erection sequence, with erection drawings and a site advisor on request.
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.
