Customers · Steel fabricators & erectors
Built-up columns and rafters, complete PEB kits and long-span members made to your drawings or ours, from 2,500 T of monthly capacity. You keep the client and the erection; we make the steel and deliver it marked, bundled and ready to erect.
What you need

Thai steel fabricators and erection teams often face the same problem: a large factory building or warehouse project arrives when the workshop is already booked, or it needs heavy built-up members your lines cannot make.
With World Steel as your fabrication partner you can take the job, keep your client and your erection crew busy, and let our factory make the frame. We never bid for your client\'s project: we are your supplier.

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.
