Modern steel structure aircraft maintenance hangars are engineered to deliver exceptional durability, spaciousness, and operational efficiency for aviation industry professionals worldwide. As a one-stop provider of design, fabrication, and installation services, our large-span steel hangars feature sleek minimalist designs—characterized by seamless rooflines, high-strength steel framing, and corrosion-resistant coatings that withstand extreme weather conditions (from frigid temperatures to coastal humidity). Ideal for housing narrow-body, wide-body, or regional aircraft, these hangars offer unobstructed interior space (customizable lengths up to 150+ meters) to support maintenance, repair, and overhaul (MRO) operations, including engine overhauls, airframe inspections, and component replacements. With precision-engineered steel components, our hangars ensure structural stability, quick construction timelines, and long-term cost savings—making them the preferred choice for airports, airline fleets, and MRO service providers seeking reliable, future-ready aviation infrastructure.
| 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. |
| 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 steel structures 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. |
