Work must fit a school break
Steel is made while the old building is still in use, then erected in weeks.

Customers · Schools, hospitals & communities
Classroom blocks, sports halls, covered courts, hospital car parks, covered walkways and community halls. We design and fabricate the steel structure in our own factory and deliver it ready to bolt, so your Thai contractor finishes on site in weeks, not months.
What you need

Schools and hospitals cannot stop. A new classroom block, sports hall, covered court or hospital car park has to be built in a short window, close to students, patients and visitors, and it must be safe for decades.
Prefabricated steel moves most of the work into our factory. We design and fabricate the structure, and the Thai contractor erects it with bolts in a few weeks, with less noise, dust and traffic on site.

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.
