Each tenant wants something slightly different
One base design with options: crane runway, mezzanine, canopy, higher eave. Changes are made in the model, not on site.

Customers · Industrial estate operators
Speculative ready-built factories, warehouses for lease, estate facilities and tenant fit-outs, all from one repeatable steel design. Our engineers design it, our factory makes it, and the steel arrives at your estate gate on the date you plan.
What you need

Investors choosing between estates in the EEC, Ayutthaya or the north compare more than land prices. A ready-built factory or a warehouse for lease that is ready to move into can win the tenant.
You need a steel supplier that builds a standard you can repeat, adapts it quickly to a tenant's crane, floor load or office mezzanine, and delivers on a schedule that matches your sales pipeline.
Your challenges, our answers

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.
