"I don't know what it will cost"
A clear steel price and tonnage based on your size, before anything is ordered.

Customers · SMEs, shop owners & homeowners
A warehouse behind the shop, a workshop, a shophouse extension, a carport or a steel-frame home. We design and fabricate the steel structure and purlins in our own factory, give you a clear price and deliver ready to bolt for your local Thai builder.
What you need

For a family business every baht counts. A small warehouse, workshop, showroom, carport or re-roofing job has to fit the plot, the budget and the time the shop can be disturbed.
We design the steel frame to your size and use, fabricate it in our own factory and send it ready to bolt. Your local Thai builder does the foundations, roofing, walls and finishes. You get one clear price for the steel and drawings your builder can follow.

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.
