Challenge 01
Start of production is fixed by the OEM
Our answer
We book fabrication at order and ship by erection zone, so the shell and crane runways are ready for machine installation on time.

The Thai automotive industry
A supply chain that cannot wait for its buildings
Thailand is South-East Asia's largest vehicle production base, with assembly plants and hundreds of Tier 1 and Tier 2 suppliers clustered in Chonburi, Rayong, Chachoengsao and the Bangkok periphery. The shift to electric vehicles is bringing new battery, motor and electronics plants into the EEC.
Car makers launch models on fixed dates and expect suppliers to be ready for production trials. For a parts maker that means a factory with crane-served bays, stiff frames for precise machines and space to add a line when the next contract arrives. Steel is the fastest way to deliver all of it.
- Crane runways designed with the frame, not added later
- Stiff frames and floors for presses, CNC and robotic cells
- Bays sized for line layouts and AGV routes
- Future extensions planned for the next model or contract
Your challenges, our answers
What automotive suppliers ask us, and how we solve it
The questions we hear from OEMs, Tier 1 and Tier 2 suppliers planning plants in Thailand.
Challenge 02
Heavy overhead cranes
Our answer
Crane girders, brackets and runway columns designed with the frame for the crane capacity, span and duty class you specify.
Challenge 03
Presses and precise machines
Our answer
Frames and mezzanines checked for stiffness and vibration, with column positions agreed around foundations and pits.
Challenge 04
EV battery and electronics zones
Our answer
Clean, dry rooms with support steel for HVAC, dust collection and fire separation where battery storage needs it.
Challenge 05
Expansion for the next model
Our answer
End walls and crane runways designed to extend, so a new line can be added without stopping the plant.
Challenge 06
Corporate engineering standards
Our answer
Global OEM and supplier specifications reviewed with your team and applied alongside Thai codes.
What we build

Inside the structure
Engineered for cranes, presses and production lines
Typical design choices. Every project is engineered to its own brief, site and standards.
| Design item | Typical approach |
|---|---|
| Clear span | 24–40 m bays for production lines, multi-span for large plants |
| Overhead cranes | Runways for single- or double-girder cranes, typically 5–50 T |
| Eave height | Set by hook height of the crane plus clearances |
| Mezzanines | Platforms for offices, HVAC and equipment, checked for vibration |
| Roof services | Loads for HVAC, ducts, compressed air, sprinklers and solar PV |
| Wind and seismic | DPT 1311-50 and DPT 1301/1302-61 for your province |
| Coating | ISO 12944 system for inland or coastal EEC sites |
Design highlights
- 01
Crane-first design
Crane loads, deflection limits and runway alignment are part of the first model, not an add-on.
- 02
Line-friendly grid
Columns placed on your process layout so lines, AGVs and forklifts move freely.
- 03
Ready for the next line
Extendable end walls and runways for future bays.
- 04
Precise fabrication
Members fabricated and inspected in our ISO 3834-2 certified factory, so crane runways fit first time.

FAQ
Questions Thai clients ask us
Can you design crane runways?
Yes. Send the crane capacity, span, hook height and duty class; we design the runway girders, brackets and columns with the building frame.
Do you follow OEM or corporate engineering standards?
Yes. We review your specification at the start and apply it alongside Thai codes and our standard AISC and MBMA practice.
How quickly can a parts factory be delivered?
Approval drawings usually take 1–3 weeks, fabrication 3–6 weeks depending on tonnage, and sailing to Laem Chabang a few days. Fabrication runs while your foundations are built.
Can we extend the plant later?
Yes. We design end walls and crane runways to extend, so new bays can be added with limited disruption.
