Product Overview

A steel structure aircraft hangar typically consists of a primary steel frame, secondary structural members, roof and wall systems, aircraft hangar doors, foundations and connections, together with optional equipment and accessories.

The main structure is generally fabricated from high-strength structural steel and designed to provide sufficient strength and stability while maintaining a large unobstructed interior space.
Our Steel Structure Aircraft Hangars are engineered for aircraft storage, maintenance, inspection, repair, and operational support. Designed with large clear spans, high-strength steel frames, and customized aircraft access solutions, our hangars provide a safe, durable, and cost-effective enclosed space for a wide range of aircraft applications.

The hangar structure can be fully customized according to aircraft dimensions, site conditions, local building codes, wind and snow loads, crane requirements, door configuration, and other project-specific requirements.

Main Structural Components

1. Primary Steel Frame

The primary frame normally consists of:

• Steel columns
• Roof beams / rafters
• End-wall frames
• Base plates
• Connection plates
• High-strength bolts

The frame is designed to withstand applicable dead loads, live loads, wind loads, snow loads, seismic loads, and other project-specific loads.

2. Secondary Steel Structure

Secondary structural members may include:

• Roof purlins
• Wall girts
• Bracing systems
• Tie rods
• Struts
• Knee braces
• Door framing
• End-wall framing

These components transfer loads between the enclosure system and the primary steel frame while providing overall structural stability.

3. Roof System

The roof system can be customized according to climate and insulation requirements.

Typical options include:

• Color-coated steel roofing
• Insulated sandwich panels
• Rock wool sandwich panels
• Glass wool insulation systems
• Skylight panels
• Roof flashing and trims
• Gutters and downpipes

4. Wall System

The wall enclosure may consist of:

• Insulated sandwich panels
• Single-layer profiled steel sheets
• Rock wool panels
• Glass wool insulation systems
• Flashings and trims
• Ventilation components

The wall system can be selected according to thermal insulation, fire resistance, appearance, and local climatic requirements.

5. Aircraft Hangar Door

The hangar door is one of the most important components of an aircraft hangar. Door dimensions and opening arrangements are determined according to the aircraft size and required operating clearance.

Door systems can be equipped with:

• Electric drive systems
• Manual or automatic operation
• Safety protection systems
• Control systems
• Weather seals
• Emergency operation systems

Typical Technical Specifications

Key Features

Large Clear Span

The steel portal frame system allows large interior spaces with minimal or no intermediate columns, providing unobstructed aircraft movement and maximizing the usable floor area.

Customized Hangar Dimensions

The hangar width, length, eave height, roof slope, bay spacing, and door dimensions can be customized according to the aircraft type and operational requirements.

High-Strength Steel Structure

The primary structural system is fabricated from high-quality structural steel and designed according to applicable international or local design standards.

Large Aircraft Doors

Hangar doors can be customized according to aircraft dimensions and operational requirements. Available configurations may include:

• Sliding hangar doors
• Bi-fold doors
• Hydraulic doors
• Rolling doors
• Vertical-lift doors
• Customized large-span door systems

Durable Enclosure System

Roof and wall systems can be configured with insulated sandwich panels or other suitable cladding systems to provide weather protection, thermal insulation, and long-term durability.

Flexible Interior Layout

The column-free or large-span interior allows flexible arrangement of aircraft, maintenance equipment, workshops, storage areas, offices, and other supporting facilities.

Crane and Equipment Integration

The steel structure can be designed to accommodate overhead cranes, maintenance equipment, lighting systems, ventilation systems, suspended loads, and other building services where required.

Design Considerations

Each aircraft hangar is designed according to the specific project requirements.

Important design parameters include:

Building Dimensions

• Building width
• Building length
• Eave height
• Roof height
• Bay spacing
• Aircraft clearance requirements

Environmental Loads

• Basic wind speed
• Snow load
• Seismic conditions
• Temperature conditions
• Exposure category
• Site elevation

Operational Requirements

• Aircraft type and dimensions
• Aircraft access requirements
• Hangar door dimensions
• Maintenance equipment
• Overhead crane requirements
• Suspended loads
• Lighting and ventilation
• Internal working space

Local Regulations

The structural design can be prepared according to applicable local building codes and project specifications.

Aircraft Hangar Door Design

Large aircraft doors require careful consideration of structural loads, operating frequency, weather conditions, and available space.

We can provide customized door opening dimensions and structural framing based on the aircraft's:

• Overall length
• Wingspan
• Tail height
• Fuselage dimensions
• Required operating clearance

The door structure and surrounding steel framing are designed as an integrated part of the hangar building.

Structural Steel Fabrication

All major steel components are fabricated according to approved fabrication drawings and project specifications.

Our fabrication process generally includes:

1. Raw material inspection
2. Steel cutting
3. Component preparation
4. Assembly
5. Welding
6. Dimensional inspection
7. Surface preparation
8. Painting or protective coating
9. Component marking
10. Final inspection
11. Packing and shipment

Steel components can be manufactured according to project-specific drawings, material grades, welding requirements, coating specifications, and quality standards.

Surface Treatment and Corrosion Protection

Steel components can be protected according to the project's environmental conditions and durability requirements.

Available options include:

• Shot blasting
• Primer coating
• Intermediate coating
• Topcoat
• Heavy-duty protective coating
• Hot-dip galvanizing for selected components

The coating system can be customized according to the project location, service environment, and specified service life.

Insulation Options

For aircraft maintenance facilities and enclosed hangars, insulation can be selected according to the required indoor environment.

Typical insulation solutions include:

• Rock wool sandwich panels
• Glass wool insulation
• PIR/PUR sandwich panels
• Composite roof insulation systems

The insulation thickness and material can be selected according to local climate and thermal performance requirements.

Optional Systems

Depending on the project requirements, the aircraft hangar can be integrated with various auxiliary systems and equipment, including:

• Overhead cranes
• Aircraft maintenance platforms
• Ventilation systems
• Natural ventilation
