Durable Steel Structure Hangar Featuring Large Span Design Ideal for Aviation

A Steel Structure Hangar is a specialized large-span building designed for aircraft storage, maintenance, inspection, and aviation-related operations. The structural system provides a spacious, unobstructed interior with sufficient aircraft clearance and large access openings for efficient aircraft movement.

The hangar can be customized for different aircraft types—from small private aircraft and helicopters to larger commercial or cargo aircraft—according to required dimensions, operational conditions, and site requirements.

A steel hangar typically consists of heavy-duty steel columns, roof beams or trusses, purlins, wall girts, bracing systems, connection components, and large aircraft access doors.

Unlike conventional industrial buildings, hangars require particular attention to clear span, internal height, door opening dimensions, aircraft movement, and operational clearance. These factors are incorporated into the structural design from the beginning.

The building can also include maintenance areas, offices, storage rooms, equipment spaces, ventilation systems, lighting, and other aviation-related facilities.

The hangar structure is developed around the aircraft and its actual operating requirements. Design considerations include:

• Aircraft dimensions and wingspan
• Overall aircraft height and length
• Landing gear clearance
• Aircraft entrance and exit routes
• Maintenance areas and ground equipment
• Internal circulation patterns
• Required working clearance
• Future aircraft requirements

This ensures the building provides sufficient space not only for aircraft storage but also for daily maintenance and operational activities.

Steel Structure Hangars can be used for:

• Aircraft storage and maintenance
• Aircraft inspection facilities
• Private and commercial aviation facilities
• Cargo aircraft facilities and helicopter hangars
• Aviation training centers
• Airport support buildings
• Aircraft equipment storage
• Government aviation facilities
• Aviation maintenance workshops

The hangar door is one of the most important functional components. Its dimensions and opening method are designed according to aircraft type and required operating clearance.

Possible solutions include:

• Sliding hangar doors
• Bi-fold doors
• Folding doors
• Telescopic sliding doors
• Customized large-span door systems

Door size, opening direction, operating method, and structural support are coordinated with the main steel frame.

Aircraft require unobstructed space for parking, movement, inspection, and maintenance. The structural system is designed with large spans and appropriate column arrangements to minimize interference with aircraft operations.

The required clear height is determined according to the aircraft's overall height, door dimensions, equipment requirements, and maintenance activities.

For hangars used for maintenance or inspection, additional functional areas can be integrated into the building layout:

• Aircraft maintenance bays and inspection areas
• Tool and spare parts storage
• Ground support equipment areas
• Technical offices and staff rooms
• Equipment rooms and specialized workspaces

The layout is planned to maintain sufficient working space around the aircraft.

Hangars require effective ventilation and lighting depending on their use. The building can incorporate:

• Roof ventilators and wall louvers
• Mechanical exhaust systems
• Natural ventilation openings
• Skylights and industrial lighting
• Customized ventilation systems

For maintenance facilities, ventilation requirements are coordinated with the specific operational environment.

A hangar requires a structural system capable of safely handling the loads associated with a large-span building. Engineering considerations include:

• Dead loads and roof live loads
• Wind, snow, and seismic loads
• Equipment and crane loads
• Door loads and operational stresses
• Local building regulations and standards

The structural design can be adapted to applicable Chinese, European, American, or other required design standards.

Our engineering team develops hangar solutions based on aircraft and site requirements. For initial design, useful information includes:

• Aircraft type and dimensions (wingspan, height)
• Building length, width, and required clear height
• Aircraft door dimensions and access requirements
• Project location and environmental conditions
• Maintenance requirements and operational needs
• Available drawings and site specifications

If complete drawings are not available, basic aircraft and building dimensions can be used to develop a preliminary concept.
