What we supply in Thailand
Four things, done exceptionally well
In Thailand we focus on what decides the safety, speed and cost of a steel building: the engineered steel frame and its purlins. Roof sheets, concrete and erection stay with the Thai partners you already trust – we make sure everything fits first time.

Value Engineering · VE
Value Engineering: the same building, less investment
Before we quote, our engineers look for every baht that does not add strength or value – and show you the saving in tonnes and baht.
10–20%typical steel-weight saving against a conventional hot-rolled design
- 01Tapered built-up members
Steel placed where the forces are – deep at the knee, slim at mid-span.
- 02Right frame & bay spacing
We compare clear-span, multi-span and bay options to find the lightest layout for your use.
- 03Continuous lapped Z-purlins
High-tensile G450/G550 purlins lapped over supports carry more with less steel.
- 04Smaller foundation loads
Optimised bracing and pinned bases reduce column reactions – and the concrete under them.
- 05Fire paint only where needed
Member-by-member fire design cuts intumescent thickness, often the biggest hidden cost.
- 06Fewer containers, faster erection
Nested packing and erection-sequence bundles cut freight and crane time on site.
100+projects in Thailand since 2019
Quality proven in Thailand
100+ Thai projects. One certified standard of quality.
Since 2019, more than 100 warehouses, factories, stores, markets and car parks across Thailand have been built on World Steel frames. Every one was fabricated, inspected and documented with the same certified process we use for projects in the United States and Australia – which is why Thai owners and contractors keep coming back.
Certified welding & fabrication
ISO 3834-2, EN 1090 EXC3, AS/NZS 5131 CC3 and IAS AC472 – audited by independent bodies, not self-declared.
Modelled in 3D, fit-checked
Every frame is modelled in Tekla and every connection checked before cutting, so bolts line up on your site the first time.
Inspected lot by lot
Dimensions, welds and paint thickness checked against an inspection and test plan, with records you can request for any member.
Delivered as documented
Piece marks, packing lists and erection drawings match each container, so your Thai erection team knows exactly what arrived.
Our factory
A 20,000 m² factory that works to your Thai schedule
Our own fabrication plant in Hai Son Industrial Park, Tay Ninh – opened in 2016, one hour from the deep-sea ports of southern Vietnam – produces 2,000 tonnes of structural steel every month. Because cutting, welding, blasting, painting and QA all happen under one roof, we give you a fabrication date and keep it. From the port, your steel reaches Laem Chabang in about 3–5 days at sea.

Why Thai clients choose World Steel
Lower total cost. Less risk. A frame that fits on the first lift.
Certified like few in Asia
ISO 3834-2 welding, EN 1090 EXC3, AS/NZS 5131 CC3 and IAS AC472 – the first fabricator in Asia to hold it. Thai projects get the same QA as our US and Australian work.
Erection-ready packages
Every piece is marked, bundled and loaded in erection sequence, with anchor-bolt plans sent before shipment so your foundations are ready when the steel arrives.
Fire protection that costs less
We size members and choose the coating together, cutting intumescent thickness – often the biggest hidden cost in a fire-rated steel building.
One price to your port or site
CIF or DDP: fabrication, packing, ocean freight, insurance and – for DDP – customs, duties and trucking in one transparent quotation.
Engineers who speak your project
English- and Thai-speaking support, drawings in Tekla and IFC models, and a single project manager from quotation to the last bolt.
ไทย
Thai craftsmanship, world-standard steel
Built for Thailand
We understand how Thailand builds
A building in Thailand is more than steel. It has to stand the monsoon, the sea air and the heat – and it begins with a ceremony. We plan for all of it.
- ๑
Ready for your Sao Ek ceremony
Tell us the auspicious date for your Yok Sao Ek (raising of the first column) and we schedule fabrication and shipping so the first column is on site and ready to lift.
- ๒
Designed for the monsoon
Wind loads to DPT 1311-50 and ASCE 7, with roof drainage and bracing sized for the south-west monsoon and tropical storms.
- ๓
Protected against heat and sea air
Paint and galvanising systems chosen for Thai humidity – up to C5 for coastal sites in Chonburi, Rayong, Songkhla and Phuket.
- ๔
Planned around Thai holidays
Vessels and port slots planned around Songkran, New Year and Chinese New Year, so your steel is never stuck at Laem Chabang over a long holiday.

A quality management system that makes buildings last
ISO 9001 · 14001 · 45001
Quality, environmental and occupational-safety management systems, certified and audited every year.
Independent QA/QC department
Inspectors report to quality management, not to production – nothing leaves the factory on schedule pressure alone.
Six inspection stages
Incoming material, cutting & drilling, assembly, welding, surface cleaning and painting – each signed off.
Hold tags & NCRs
Any non-conformity is tagged Hold and closed with a non-conformance report before the member moves on.
Traceable materials
Mill certificates for every heat; EN 10204 3.1, CE and JIS documentation on request.
Lasting performance
Correct welds, coating thickness and connections are what keep a steel building sound for decades in Thailand's climate.
Factory to site
Three to five days at sea from our factory to Laem Chabang
Our factory is about 100 km by road from Cai Mep – Vietnam’s deep-sea gateway with weekly direct sailings into the Gulf of Thailand. Steel reaches Laem Chabang, Bangkok Port, Map Ta Phut or Songkhla faster than many domestic mills can roll and fabricate it, and we have delivered to sites from Mae Sot and Khon Kaen down to Phuket and Hat Yai.

Your choice of Incoterm
CIF to the port, or DDP to your gate
To a Thai port
We deliver to a Thai port with freight and marine insurance paid. Your customs broker clears the cargo and trucks it to site – ideal when you already import regularly.
To your site, duties paid
We handle everything to your site: export, freight, insurance, Thai customs clearance, import duty and VAT, port charges and trucking. You receive steel, not paperwork.
Fire safety, engineered
Fire-rated steel without the fire-rated price tag
Intumescent paint can cost as much as the steel it protects. We cut that cost at the design stage: choosing sections with a lower section factor, matching each member to the manufacturer’s assessed thickness tables and applying the coating in our factory, where thickness is controlled and recorded.
- R30 – R120 fire resistance
- Third-party assessed products (EN 13381-8, BS 476, UL 263)
- Shop-applied, DFT recorded per member
- Topcoats for humid and coastal Thai climates

Questions Thai clients ask us
Do you erect the building in Thailand?
We design, fabricate and deliver the steel structure and purlins. Erection is done by your Thai contractor or an erection team you appoint; we provide erection drawings, bolt lists and engineering support, and can send a site supervisor on request.
Can you supply roof and wall sheeting?
For Thailand we deliberately supply only the steel structure and purlins. Roof and wall sheets are best bought locally – we design purlin spacing and details to suit the Thai sheeting brand and profile you choose.
Which design standards do you use?
US codes by default (AISC 360, AISI S100, ASCE 7, MBMA), with wind and seismic loads checked against Thai DPT standards (มยผ. 1311-50 and มยผ. 1301/1302-61). Drawings are prepared so your Thai licensed engineer can review and sign them for the building permit.
How long does a project take?
For a standard warehouse, design and approval drawings take 1–3 weeks, fabrication 3–6 weeks depending on tonnage, and sea transit to Laem Chabang typically 3–5 days, plus customs clearance.
Is there import duty on steel structures from Vietnam?
Steel structures (HS 7308) made in Vietnam can qualify for ASEAN preferential duty under ATIGA when a Form D certificate of origin is issued – we provide it. VAT at 7% applies on import. Your customs broker confirms the final classification; on DDP terms we handle it for you.
What is the minimum order?
There is no fixed minimum – we have delivered 12 × 18 m stores as well as 300 m-long warehouses. Small orders are consolidated into shared containers to keep freight economical.
