Wingspan sets the width of a hangar, tail height sets the door, and the lease sets everything else. That last one surprises first-time hangar owners. On most public airports the ground under a hangar belongs to the airport sponsor, so before steel is ordered you may need an approved lease, a site plan accepted by the airport, and a design that respects taxiway setbacks and height limits.
Hangars come in three families. T-hangars and row hangars shelter single-engine aircraft in small units. Box hangars hold one or a few aircraft, sometimes with an office and shop. Maintenance and storage hangars for larger aircraft and fleets are clear-span structures with big doors, heavy slabs and fire suppression. Steel suits all three, which is why metal is the default material at general aviation fields.
We build hangars in Oklahoma as pre-engineered steel buildings designed around the aircraft, the door and the airport rules. For the broader service, see aircraft hangars, and for the door side of the job, overhead hangar doors. This page looks at the building type and the Oklahoma airport setting.
Aviation is a substantial sector in Oklahoma. At Tulsa International Airport, a 2020 report described an American Airlines investment of $550 million over seven years in its maintenance base, including a 193,000-square-foot hangar for larger planes and a 132,000-square-foot base support building. At Will Rogers World Airport, AAR broke ground in April 2024 on an expansion adding more than 80,000 square feet of hangar and warehouse space and 200 full-time positions.
Smaller fields matter just as much. A general reference source reports that a $120 million aerospace maintenance investment was announced for the Clinton-area spaceport in October 2022 and that a large maintenance hangar there opened in October 2025, though we have not verified the details. Ardmore Municipal Airport has a 9,002-foot concrete runway with an ILS approach. Large or small, these fields attract hangar demand from owners, flight schools, charters and repair shops. See the Tulsa International aerospace district and Ardmore.
A hangar sits under several rulebooks at once. The airport sponsor controls land use, the FAA governs airspace and obstruction, and the city or county building department enforces the building code. Height limits near runways are set by airspace standards, and a tall hangar close to a runway may require an FAA notice. Ask about this before design. Oklahoma sets statewide minimum codes through the Uniform Building Code Commission, and the International Building Code is, while cities adopt their own editions.
Fire protection scales with size and use. Large maintenance hangars often need foam or high-expansion systems, detection and separation of fuel and paint areas, while a small storage hangar has far lighter requirements. The authority having jurisdiction decides, and the insurer has views too. For public airports, work funded with public money brings competitive bidding rules and accessibility requirements, which the airport sponsor will explain.
We ask for the aircraft types you own now and the ones you might own later. Wingspan, tail height, turning radius and weight set the door opening, the clear width, the clear height and the slab. A hangar sized for a single piston plane may be too small for a turboprop, and the owner discovers it at resale. When the budget allows, we suggest a size with room for the next airplane.
Doors are the largest decision after size. Bi-fold, hydraulic and sliding doors each have different clearances, power needs, wind behavior and cost. We lay out the options with prices and with plain notes on maintenance. Electrical service, lighting, ventilation, a floor that sheds water and a floor drain with an oil trap if required complete the basic package. Heat is a quiet issue in Oklahoma summers, since an uninsulated steel roof over a closed hangar can make the space hard to work in and hard on avionics. Our design-build service keeps the airport lease, permit and construction on one timeline.
The slab is not a warehouse slab. Aircraft are heavy on small contact areas, tugs need smooth floors, and a floor that slopes to the door sheds spilled fluids and washdown water. The connection between the hangar floor and the apron needs a proper joint and drainage so water does not run into the building. Airfield soils can be soft, and the geotechnical report guides footings.
Utilities and access also need thought. Airport ground may have limited sewer, and electric service can be a long run. Taxilane access, ramp pavement and drainage across the lease area are part of the project. When an owner plans a group of hangars, we often design shared utilities and a common apron. See aviation work for the owners and operators we hear from most.
The package is built on the same pre-engineered metal building system as any other steel structure, and it starts with the steel frame, wall and roof panels and the hangar door system. It adds a slab with embeds for the door track, personnel doors, insulation where needed, lighting, power, and any office or shop space. Many owners ask for a lean-to or an attached office, and for a shop with a bench and compressed air.
Insulation depends on how the hangar is used. A cold storage-only hangar may need little, while a shop that heats in winter benefits from a good envelope. We also plan for ventilation to deal with the heat that builds under a steel roof. For larger maintenance projects, a manufacturing plant style design with a crane or a mezzanine for parts storage can be added to the frame from the start.
Maintenance of the finished hangar is simple but worth doing. Door tracks, cables, seals and hydraulic parts wear, and a yearly inspection by a qualified door technician avoids a stuck door on the day you need the airplane. We provide a short care sheet at turnover so the owner knows what to check.
Tell us the aircraft types, the airport and the lease status. We will return a hangar size, a door recommendation, a budget range and the approvals that have to happen first.
On most public airports, yes. The sponsor controls land and must approve the lease, site plan and often the design. Talk to the airport manager before ordering anything.
Measure the largest aircraft you may own, then add room to move around it. Wingspan sets the width and tail height sets the door. Add a little extra for a tug, tools and storage.
It depends on the opening and wind exposure. Bi-fold doors are common, hydraulic doors are popular for big openings, and sliding doors suit some layouts. We compare cost, clearance and maintenance.
Usually, yes, if the code and the airport allow it. Fire separation, ventilation and restroom needs apply.
Yes, they trigger stricter fire and ventilation rules. Tell us at the start if you plan to fuel, paint or do maintenance inside.
Tell us about the site, the building and the schedule, and we will set up a review of scope, schedule and permitting.
