Our Helicopter Steel Structure Hangar is the best way to protect your expensive rotary-wing aircraft. It works well and lasts a long time. These special pre-engineered buildings have big frames with no interior columns, so the floor room is bigger for rotor clearance and moving the plane around. To make rigid portal frames that can hold big dynamic loads, like overhead cranes for maintenance work, our product systems use high-strength H-section steel beams and columns.
Director Steel knows exactly what you need because he has worked in flight systems for more than 12 years. When compared to standard concrete buildings, our hangars cut construction times by 30 to 50 percent and are better at withstanding high wind loads, which is important for airport safety.
Your plane should have clear room. The clear spans of our hangars range from 20m to 60m+, with no columns in the middle. This design can work with rotors of different diameters and gives your maintenance teams the most operating freedom possible.
We utilize high-quality structural steel (Q355B/ASTM A572 Gr.50) that has a bending strength of at least 345 MPa. This keeps the structure light without lowering its ability to hold weight. With our high-quality products, your investment will be safe for decades.
Every day, the weather outside your hangar is very bad. We use shot blasting to a Sa2.5 grade, then an epoxy zinc-rich base, and finally polyurethane topcoats in our heavy-duty anti-corrosion systems. For areas near the coast, we offer hot-dip galvanization (600g/m²), which makes sure that the metal will last for a long time.
Needs related to the weather can't wait. The wind speeds in our hangars can go over 140 km/h, and they can hold the right amount of snow. To give you peace of mind, we make sure that every building we build meets AISC or Eurocode 3 standards.

Commercial aviation firms rely on our reinforced roof structures to support heavy lifting hoists and integrated mezzanine floors. The Helicopter Steel Structure Hangar ensures stability during precision engine removal operations while providing space for parts storage and technical offices.
Coastal and offshore rescue bases benefit from our galvanized steel frames with C5-M grade anti-corrosion coatings. These hangars maintain 24/7 operational readiness despite saltwater exposure and high coastal winds.
Tactical forward operating bases utilize our modular, bolted connections for rapid deployment. These hangars accommodate camouflage systems and ballistic resistance integration while providing immediate shelter in harsh terrain conditions.
Quality control follows strict aviation and structural safety protocols. We implement 100% visual inspection coupled with non-destructive testing on critical load-bearing nodes. Pre-assembly of primary frames at our factory ensures bolt hole alignment and span tolerance within ±2mm.
Our 40,000 square meter production facility houses six automatic welded H-beam production lines and employs over 200 skilled workers. Third-party certification bodies like SGS, BV, and TUV verify that every structure meets specific wind load and seismic requirements before shipment.
You receive complete project support from concept to completion. Our in-house architectural design team provides structural calculations, customized engineering, fabrication, and installation guidance. We manufacture everything from steel frameworks to roofing systems, cladding, windows, and doors.
Every project receives custom engineering tailored to your specific requirements. Whether you need overhead crane support, specialized door systems, or climate control integration, we adapt our designs to your operational needs.
Our technical team provides detailed installation guidance ensuring proper assembly. We supply comprehensive drawings, connection details, and on-site consultation to guarantee structural integrity.
Your hangar requires seamless access for aircraft movement. Our steel structures accommodate electric bi-fold doors, hydraulic swing doors, and multi-leaf bottom rolling sliding doors. These systems ensure full-width opening clearances for rotor blades while maintaining structural stability.
Temperature stability protects sensitive avionics and ensures mechanic comfort. Our roof and wall systems integrate with sandwich panels featuring PU, rock wool, or glass wool insulation. We tailor R-values to your specific climate requirements.

Every Helicopter Steel Structure Hangar project starts with understanding your unique requirements. Contact our engineering team for detailed consultations, structural calculations, and custom design proposals.
