Clear-span portal frames
Column-free spans for warehouses, hangars and sports halls; tapered members keep steel weight down on wide spans.
Steel structures & pre-engineered buildings
The steel frame of your building – engineered, fabricated and delivered to Thailand
Pre-engineered portal frames for fast, economical warehouses and factories, and heavy structural steel for crane buildings, mezzanines and multi-storey frames – all from one certified factory.
Why steel – and why pre-engineered – for Thai buildings
A pre-engineered building (PEB) uses tapered built-up columns and rafters, sized by software to follow the bending moment along each member. Steel goes only where the loads are, so a typical PEB warehouse needs noticeably less steel than a frame of standard hot-rolled sections – and arrives on site as a bolted kit.
For Thai owners that means a building that is faster to permit, faster to erect and easier to extend: column-free spans for racking and forklifts, roofs designed for monsoon rainfall and coastal wind, and a structure that can grow with the next phase of your business.
Steel structures & PEB
Structural systems we design and fabricate
Multi-span frames
Interior columns for very wide footprints – distribution centres, factories and markets of any width.
Crane buildings
Runway beams, brackets and frames designed for overhead cranes, with fatigue and deflection checks to AISC and CMAA guidance.
Mezzanines & multi-storey frames
Office mezzanines, storage platforms, car parks and multi-storey steel frames with composite floors.
Trusses & long-span roofs
Lattice trusses and space-saving roof structures for markets, stadium stands and showrooms.
Canopies, carports & retail
Fuel-station canopies, carports, store frames and façade steel for retail chains rolling out across Thailand.

FAQ
Questions Thai clients ask us
How much steel does a PEB warehouse use?
It depends on span, eave height, bay spacing, loads and cranes. As a rough guide, simple PEB warehouses without cranes often fall in the 25–45 kg of steel per m² range; we give you the exact weight with the quotation.
Can you match an existing building or extend it?
Yes. Send us photos and the existing drawings, or a survey of column positions and heights – we design the extension frame to tie in with the existing structure.
Can the roof carry solar panels?
Yes, if it is designed for them. Tell us the panel system and we add the extra dead load and wind uplift to the design – far cheaper than strengthening later.
Do you supply hot-dip galvanised steel?
Yes, for exposed or corrosive environments such as coastal sites, livestock buildings and fertiliser stores we offer hot-dip galvanising or high-performance paint systems.
