The Thai electronics industry
Global supply chains are moving into Thailand
Electronics and electrical appliances are among Thailand's largest export industries. Hard-disk drives, printed circuit boards, air conditioners, appliances and now semiconductors and data-centre components are made in estates across Ayutthaya, Pathum Thani, Prachinburi, Chonburi and Rayong, many of them by international groups relocating capacity to Thailand.
These plants are service-heavy buildings: the roof carries air handling, clean-room ceilings, exhausts and cable trays, and the floor carries sensitive equipment. The structure has to be stiff, flat and coordinated with every service, and it has to be ready before the customer's qualification audit.
- Long spans that keep clean rooms free of columns
- Roof and ceiling steel sized for heavy HVAC and clean-room services
- Frames checked for deflection and vibration around sensitive equipment
- Modular bays that let you add capacity as orders grow
Your challenges, our answers
What electronics manufacturers ask us, and how we solve it
Issues raised by electronics and appliance makers setting up or expanding in Thailand.
Challenge 02
Vibration-sensitive equipment
Our answer
Frames and mezzanines checked for stiffness, with heavy equipment placed on independent foundations where needed.
Challenge 03
Fast relocation of capacity
Our answer
Fabrication slots reserved at order and steel shipped by erection zone, so the building is ready for the qualification audit.
Challenge 04
Flatness and tolerances
Our answer
Members fabricated to tight tolerances and inspected before shipment, so ceilings and wall panels align.
Challenge 05
Fire separation and storage
Our answer
Fire walls, separated chemical and battery stores and intumescent protection where a fire rating is required.
Challenge 06
Growing with orders
Our answer
Modular bays and extendable end walls for phase two without interrupting production.

Inside the structure
Engineered for stiffness, services and clean space
Typical design choices. Every project is engineered to its own brief, site and standards.
| Design item | Typical approach |
|---|---|
| Clear span | 24–45 m column-free, or a grid agreed with your process and clean-room designer |
| Roof and ceiling loads | Air handling, ducts, clean-room ceiling and cable trays, plus solar PV |
| Deflection | Tighter limits than standard industrial buildings where ceilings and equipment need them |
| Mezzanines | Service and equipment platforms, checked for vibration |
| Fire protection | Intumescent paint where a fire rating is required |
| Coating | ISO 12944 system for inland or coastal sites |
| Expansion | Extendable end walls and modular bays |
Design highlights
- 01
Services coordinated early
We take your HVAC and clean-room loads into the first model, so no strengthening is needed later.
- 02
Stiff where it matters
Deflection and vibration checked around clean rooms and sensitive equipment.
- 03
Ready for the audit
Mill certificates, weld and paint records ready for your customer qualification.
- 04
Shipped in erection order
Every piece marked and bundled by zone, so the first bays arrive first.

Questions Thai clients ask us
Can a steel building carry a clean-room ceiling?
Yes. We design the roof and ceiling steel for the clean-room ceiling, filter units and services loads given by your clean-room designer.
How do you control vibration?
We check the frame and mezzanine stiffness and agree with your engineer which equipment needs independent foundations.
Can you meet tight relocation schedules?
Yes. We reserve fabrication at order, and design, fabrication and shipping run in parallel with your foundations.
Do you provide documents for customer audits?
Yes. Mill certificates, welding and paint inspection records and the inspection and test plan are supplied with the steel.
