Steel Structure Aircraft Maintenance Hangars — Design, Fabrication, and Installation
Modern metal airplane hangar maintenance hangars are designed to deliver exceptional durability, expansive space, and efficient operations for aviation professionals worldwide. As a one-stop service provider covering design, fabrication, and installation, our long-span metal aircraft hangars feature a clean, streamlined design—characterized by seamless roof lines, high-strength steel frames, and corrosion-resistant coatings capable of withstanding extreme weather conditions, from severe cold to humid coastal environments.
These steel aircraft hangar are ideal for housing narrow-body, wide-body, and regional aircraft, offering unobstructed interior space with customizable lengths exceeding 150 meters. They fully support maintenance, repair, and overhaul (MRO) operations, including engine overhauls, airframe inspections, and component replacement.
Our steel airplane hangar are built with precision-engineered steel structural components, ensuring outstanding structural stability, shortened construction schedules, and long-term cost savings. This makes them the preferred choice for airports, airline fleets, and MRO service providers seeking reliable, future-ready aviation infrastructure
- Common pain points in hangars
| Key points | Causes of occurrence | Impact on purchasers |
| Large span, high clearance | Capable of accommodating large passenger aircraft (A380, B747) in a single bay, with spans typically ranging from 120 to 150 metres and roof heights exceeding 30 metres. | The structure's own weight, deflection, and material consumption are substantial, resulting in high quotations and extended lead times. |
| Strict fire and explosion prevention requirements | The interior of the hangar stores flammable substances such as fuel and lubricants, and must meet Class II fire resistance (≥2 hours) and explosion-proof requirements. | Additional costs for fireproof coatings, partition panels, etc., coupled with numerous construction procedures. |
| Corrosion resistance, weather resistance | Salt spray and humidity in coastal or high-temperature regions cause ordinary steel to rust rapidly. | Wei Hua, increasing rental and labour costs. |
| Extended construction period and high costs | On-site welding and hoisting of large-span steel structures present considerable challenges, often requiring over 6 months to complete. | Project delays will impact subsequent aircraft maintenance schedules, increasing rental and labour costs. |
| Difficulties in operational maintenance inspections | Working at height, with dense internal piping, requires shutdown or specialised platforms for routine inspections. | Maintenance costs are high, and potential hazards are difficult to detect. |
- Simplified solutions addressing pain points
| Proposal | Specific approach |
| High-strength prestressed steel structures | Utilise 0355+ prestressed strand with a mesh spacing of 6 metres, featuring fully welded joints or high-strength bolts. |
| Corrosion-resistant metal roofing | 0.6mm aluminium-zinc coated steel sheet is selected, with a fluorocarbon topcoat applied to the surface (weather resistance: 25 years). |
| Comprehensive Fire and Explosion Prevention Measures | Apply fire-resistant coating (fire resistance ≥2.5 hours) to steel components within 3 metres of fuel pipelines; install fire barriers at critical locations. Provide complementary explosion-proof water cannons (flow rate = 30 litres per second) and an automatic sprinkler system. |
| Prefabricated assembly | All structural steel columns and columns are prefabricated in the factory, with on-site work limited to lifting, bolting and secondary anti-corrosion treatment. The construction period can be compressed to approximately 30 days. |
