AVIATION HANGARS
Over the past two decades, fabric and tensile membrane hangars have moved from military field shelters into mainstream aviation infrastructure, providing shelter to everything from light aircraft and helicopters to wide-body commercial jets.
We design ours to meet the same building codes, wind ratings, and fire classifications as conventional steel buildings—even exceed them in many cases.
Fabric hangars uses a rigid frame, typically hot-dip galvanised steel or aluminium, clad with with a tensioned fabric membrane.
The membrane is not load-bearing in the traditional sense. It does the job of a weathering skin held in tension across the frame while the frame carries structural loads. Here's what makes that happen →
The most common membrane materials are:
PVC-coated polyester (the standard for permanent hangars, with a 15 to 25 year lifespan)
HDPE (popular for semi-permanent applications), and
PTFE-coated fibreglass (the premium option, with a 30-plus year lifespan and near-complete UV immunity).
The membrane panels are typically attached using a keder rail system, which allows individual panels to slide in and out for replacement without disturbing the rest of the structure.
The membrane fabric is a replaceable cladding element and not the structure itself, which makes it incredibly convenient to replace.
When the membrane reaches end of life, it is replaced in sections while the frame continues to perform, owing to its design life of 40 to 70 years or more.
Span size is a major consideration. Clear spans of 30 to 100 metres are common, with some manufacturers achieving spans exceeding 115 metres for wide-body aircraft.
Heights are designed to accommodate specific aircraft types, from single-engine light planes through to Boeing 747s and Airbus A380s. These structures are versatile beyond belief.
The typical construction sequence starts with foundations, which can range from engineered concrete pads through to helical anchors or even ballast blocks depending on the site and the permanence of the installation.
The steel or aluminium frame is then erected in sections, with the membrane panels tensioned over the frame and secured into keder rails. Because the components are prefabricated and arrive on site ready to assemble, the on-site work is significantly less labour-intensive than conventional steel construction.
For private pilots and flying clubs, fabric hangars offer an accessible entry point. Permanent structures often become aerodrome property, while fabric hangars can remain the owner's relocatable asset. This alone makes them attractive for GA operators who may need to move or who want to retain ownership of their infrastructure.
Some of the world's largest MRO (maintenance, repair, and overhaul) facilities now operate under fabric roofs. For instance, the AAR facility at Rockford Airport in the United States is a dual-hangar complex spanning over 200,000 square feet, capable of servicing Boeing 747s and Airbus A380s side by side with a 500-person workforce.
Defence forces were among the earliest adopters of fabric hangars, and they remain a major driver of innovation in this space. The appeal is rapid deployment, relocatability, and reduced logistics footprint. The Royal Air Force has reported that using deployable fabric hangars increased aircraft serviceability by 20 percent compared to aircraft stored in the open.
Helicopter operations requires lower overall height but wide door openings to accommodate rotor clearance, often at remote or temporary locations. Fabric hangars suit this well. Offshore oil and gas operations, emergency services, and rotary-wing units all use fabric hangars for helicopter protection and maintenance.
Translucent membranes transmit approximately 12 percent of filtered sunlight, creating bright, even interiors without the harsh shadows and glare of artificial lighting.
For aircraft inspection and maintenance work, this quality of light is genuinely useful. It also reduces daytime energy costs.
This is something steel hangars don't offer up so easily for obvious reasons. Fabric panels slide from their keder rails, roll up for transport, and re-install at a new location with no loss of quality. For organisations that lease aerodrome land, operate at temporary sites, or may need to move operations in the future, this is a significant practical advantage.
PVC, HDPE, and PTFE membranes are impervious to salt spray, chemicals, and humidity. In coastal or tropical environments where aircraft hangar buildings made from steel require constant maintenance to manage corrosion, fabric cladding eliminates that problem entirely.
Shaded sports courts enhance the appeal of public sports facilities. Local councils and schools that invest in these show a commitment to the well-being of their communities.
Fabric hangars make sense when:
Speed of construction is important
The site is remote or has limited foundation capacity
Relocatability has value
The primary need is weather protection and UV shading rather than climate-controlled enclosure
Budget constraints make conventional steel construction difficult to justify for the coverage area required
Organisations that need to stand up hangar capacity quickly, whether for a new aircraft delivery, a surge maintenance requirement, or a temporary operational deployment, will find fabric construction difficult to beat on timeline alone.
The Australian market for fabric hangars is still relatively young. Only a small number of domestic manufacturers and installers operate in this space, and the supply chain for large-format aviation fabric structures is less established than in North America or Europe.

Fabric hangars are typically less expensive than conventional steel buildings for equivalent coverage. The savings come from several places. The membrane cladding is lighter than steel sheeting, which reduces the frame weight and foundation loads.
Many fabric hangars can use helical anchors, ballast blocks, or simplified pad footings rather than engineered concrete slabs. The prefabricated components arrive on site ready to assemble, reducing on-site labour and equipment.
There is a caveat: fully enclosed fabric hangars with insulated liner systems, climate control, and large door systems approach steel pricing.
The dramatic cost savings apply most clearly to open-ended sunshades, basic enclosed structures, and applications where relocatability or speed of construction carry their own value.
This is where fabric hangars have the strongest advantage. A conventional steel hangar typically takes four to eight months from design through completion. A fabric hangar of comparable size can be erected in two to eight weeks.
Some manufacturers achieve installation rates of up to 2,000 square feet per day. Military deployable hangars compress this even further. A 25-metre helicopter hangar can ship in four standard containers and be erected in under four days.
For organisations that need hangar space quickly, whether due to a new aircraft acquisition, a temporary maintenance requirement, or a military deployment, the speed of fabric construction is difficult to match.
This is often the point where scepticism creeps in. The assumption is that fabric means fragile, however, modern fabric hangars are engineered to withstand wind speeds of 160 to 195 miles per hour, depending on the manufacturer and specification.
Several have survived Category 5 hurricanes and severe cyclonic events with no structural failure. A standard PVC membrane will last 15 to 25 years before replacement is needed. PTFE-coated fibreglass is largely immune to UV and can exceed 30 years.
At Greenline, we design and deliver tensile membrane structures across Australia.
While our core work is in shade and shelter for education, recreation, and commercial environments, the engineering principles are the same: steel framing, tensioned fabric, wide clear spans, and structures designed to perform in Australian conditions.
If you're looking for an aircraft hangar for sale or want to understand how tensile membrane construction could work for an aviation application, we are happy to discuss it.
