Steel Aircraft Hangar
A hangar is a door with a building behind it. The frame is engineered around the opening you need, with clear spans to 36 m and nothing in the middle of the floor.
What It Is and What It Does
Hangars and wide-opening depots put an unusual demand on a frame: most of one elevation is a hole. The bracing that a normal building takes from that wall has to be found somewhere else, and the frame around the opening has to carry the door.
Pre-engineered portal frames handle this well because the whole building is designed as one system. Clear spans reach 36 m without internal columns, and the bracing layout is engineered around the opening rather than patched in afterwards.
Members are CNC cut and drilled for bolt-up erection, supplied hot-dip galvanised or shop primed, complete with purlins, bracing and bolts.
What You Get From It
Wide unobstructed opening
The frame is designed around the door, so the clear width is a requirement rather than a leftover.
Clear spans to 36 m
No internal columns to work an aircraft, a vehicle or a boom around.
Bolt-up erection
No site welding to make the frame, which matters on airside and remote locations.
Corrosion protection specified
Galvanised or primed to suit coastal and airfield exposure.
The Situations This Product Answers
Doors treated as an afterthought
Door loads have to be in the frame design from the start, not resolved on site.
Bracing lost to the opening
A largely open elevation needs its stability found elsewhere — engineered, not improvised.
Remote and airside access
Bolt-up erection from marked members suits sites where welding plant and skilled welders are hard to mobilise.
Coastal corrosion
Airfields are often exposed; specifying galvanising up front avoids early maintenance.

How It Compares
Hangar structures compared on the things that actually govern the design.
| Pre-engineered hangar | Site-fabricated steel | Fabric shelter | |
|---|---|---|---|
| Clear opening | Engineered with the frame | Possible, slower | Limited |
| Clear span | Up to 36 m | Varies | Moderate |
| Design life | Long | Long | Short to medium |
| Site work | Bolt up | Cut and weld | Fast |
| Suits coastal exposure | Yes, galvanised | Yes, if coated | Fabric degrades |
Getting It Right on Site
Start with the opening
Clear width and height drive everything else in the frame.
Tell us the door type early
Door weight and operation are a load case, not a fitting decision.
Confirm airfield wind data
Exposed sites often govern the frame design.
Cast holding-down bolts accurately
Frame accuracy is machined; the foundation interface has to match it.

View productSteel Aircraft Hangar FAQ
What buyers ask before placing an order for this product.
How wide can the clear opening be?
The frame and bracing are engineered around the clear opening you specify, within a clear span of up to 36 m. Send the opening dimensions with your enquiry.
Do you supply the hangar door?
Door type and supplier are confirmed per project. What matters structurally is that the door loads are engineered into the frame from the start.
Is site welding needed?
No. Members are CNC cut and drilled at the factory for bolt-up erection.
Is the steel protected for a coastal airfield?
Hot-dip galvanising or shop priming is specified to suit the exposure at your site.
What information do you need to quote?
Clear opening dimensions, overall building size, eaves height, door type, and the wind and seismic loading for the site.
