Full-Width Access. No Motors. No Delays.

When your crews need to be on site at dawn, the building they're collecting equipment from needs to work first time, every time. A door that jams, ices up, or needs coaxing open on a cold morning isn't just an inconvenience — it sets the whole day back before it's started.

The Kit Buildings Steel Aircraft Hangar with bi-fold doors was built around exactly that requirement. Aviation-grade steel construction, a clear-span interior with no columns in the way, and a door system that opens the full width of the building through a simple, robust mechanism with no motors, no chains, and no complex moving parts to fail.

How Bi-Fold Doors Work — and Why It Matters

Bi-fold doors fold outward and to the sides when opened, leaving the entire entrance width completely clear. There are no overhead mechanisms reducing the usable height at the entrance — a critical advantage for equipment with raised safety frames, roll bars, or loaded trailers that would catch on the winding gear of a roller shutter system.

The mechanism itself is straightforward: robust hinges and a simple folding action with no motors, springs, or chains involved. That simplicity is what makes bi-fold doors so reliable. Roller shutter systems rely on components that wear, seize in cold weather, and require ongoing maintenance to stay operational. Bi-fold doors don't have those failure points. They open, they close, and they keep doing so consistently — including on freezing winter mornings when roller mechanisms commonly stiffen or ice up entirely.

Staff can open the full width in minutes without assistance, or partially open one side to access specific equipment while keeping the rest of the hangar sealed — useful in cold or wet conditions when limiting the exposure of stored machinery matters.

Fully Enclosed. Comprehensively Sealed.

Unlike open-fronted shelters, the Steel Aircraft Hangar is a fully enclosed structure. When the bi-fold doors are closed, comprehensive gasket sealing runs around the entire door perimeter, keeping the interior weathertight. Everything stored inside stays dry and protected regardless of what's happening outside.

The hot-galvanised steel frame and 0.7mm ribbed steel cladding provide a structure that handles the demands of daily commercial use without deterioration. After eighteen months of daily equipment movement in all weather conditions, the steel construction shows no corrosion and no structural issues. The solid visual presence of a steel-clad building with lockable bi-fold doors also signals secure, professional storage — a deterrent in itself.

Clear-Span Interior — Every Square Foot Usable

The clear-span design eliminates interior columns entirely. Equipment of all sizes — excavators, ride-on mowers, trailers, specialist machinery — can be positioned and manoeuvred throughout the full floor area without navigating around structural obstacles. Crews can walk alongside equipment as they move it through the entrance rather than squeezing through a restricted opening, and the full-width door means multiple pieces of equipment can move simultaneously during busy periods.

All equipment lives in one centralised, secure location. No travelling between multiple storage sites, no time wasted at the start of the day, no fuel costs running vehicles between sites to collect kit.

The Right Storage for Equipment-Intensive Operations

The Steel Aircraft Hangar with bi-fold doors suits any business that moves equipment in and out regularly and needs a door system that keeps up with that pace — landscaping, groundskeeping, construction, plant hire, or any operation where daily access reliability isn't optional.
