Wide-span steel hangars for Thai aviation
Aircraft hangars, MRO workshops, cargo terminals and airside support buildings with long clear spans and large door openings. Our first Thai project in 2018 was an aircraft hangar, and we bring the same team to yours.

Thai aviation
More aircraft, more maintenance, more hangar space
Thailand is one of Asia's major aviation markets, with international gateways in Bangkok, Phuket and Chiang Mai, regional airports across the provinces and a growing maintenance, repair and overhaul (MRO) cluster, including the U-Tapao area in the EEC. Air cargo for e-commerce and perishables is growing too.
A hangar is one of the most demanding steel buildings: a door opening the full width of the aircraft, a roof spanning without columns and doors, cranes and services hanging from the structure. Steel is the only practical material for these spans, and design quality decides how the doors run for decades.
- Column-free spans sized for your aircraft types
- Door-head girders designed with the door supplier
- Roof loads for cranes, docking and services
- Workshops, stores and offices integrated around the hangar

Inside the structure
Engineered for spans, doors and airside work
Typical design choices. Every project is engineered to its own brief, site and standards.
| Design item | Typical approach |
|---|---|
| Clear span | Sized by aircraft wingspan plus clearance, with built-up or truss frames |
| Door head | Truss or girder for the full door opening, with deflection agreed with the door supplier |
| Height | Tail height plus clearance for docking and cranes |
| Cranes | Overhead cranes or hoists for engines and components |
| Wind | DPT 1311-50 zone; typhoon factor where applicable in the South |
| Coating | ISO 12944 system for coastal airports |
| Transport | Members spliced to fit containers and erected with bolted joints |
Design highlights
- 01
Designed with your door supplier
Door loads and deflection limits fixed early, so doors run smoothly for decades.
- 02
Light, long spans
Optimised members reduce tonnage and foundation loads.
- 03
Airside-friendly erection
Bolted connections and sequenced deliveries for restricted sites.
- 04
Proven in Thailand
Our 200 T hangar in 2018 was our first Thai project.

Questions Thai clients ask us
What span can a steel hangar have?
Spans are set by the aircraft you need to house. We use built-up portal frames for moderate spans and trusses for wide-body hangars, optimised for weight and shipping.
Have you built a hangar in Thailand?
Yes. An aircraft hangar of about 200 T, delivered in 2018, was our first project in Thailand.
Do you supply the hangar doors?
We design the structure for the door system and coordinate with the door supplier you choose; the door itself is supplied by a specialist.
Can you work to airport security rules?
Yes. We plan deliveries and erection sequences with your contractor around airport access and working windows.
