This type of steel offers excellent ductility and seismic - resistant performance, which is crucial for multi - storey buildings. It can effectively withstand various loads such as dead loads, live loads, and wind loads, ensuring the long - term stability and safety of the building. It complies with international standards like ASTM A992, making it suitable for different construction requirements around the world.
The secondary frame uses Q345B steel, which is cost - effective and has reliable mechanical properties. It provides stable support for the main structure, contributing to the overall structural integrity of the multi - storey steel building.
Product Details
Connection Components
All connection components are made of 316L stainless steel, which has excellent corrosion resistance and oxidation resistance. This can prevent rusting and damage in the complex environment of the hangar. A connection method combining high - strength bolts and special - designed connection parts is used. It is convenient for installation, firmly connected, and facilitates later maintenance and modification, ensuring the stability of the hangar structure.
Enclosure Panels
Wall System
Outer layer: 0.8mm - thick colored aluminized zinc profiled steel sheet with an aluminized zinc content of 250g/㎡. It has excellent corrosion - prevention ability, being able to effectively resist the erosion of rainwater, humid air, and corrosive gases. The colors are long - lasting, and various colors can be selected according to the overall style of the airport.
Insulation layer: 100 - 200mm - thick polyurethane sandwich panel with a thermal conductivity of ≤ 0.025W/(m·K). It has excellent heat - insulation and heat - preservation performance, which can effectively maintain a stable temperature in the hangar, reducing heat loss in winter and heat inflow in summer. This helps to protect aircraft components from temperature - related damage and also provides a more comfortable working environment for maintenance personnel.
Inner layer: 0.6mm - thick anti - static color steel sheet. The surface is smooth and easy to clean. The anti - static function can prevent the generation of static electricity, which is crucial for protecting sensitive aircraft electronic components.
Roof System
Panel: 1.0mm - thick aluminized zinc color steel sheet. The unique corrugated - type profiled design significantly enhances the roof's drainage and wind - resistance capabilities. It can avoid damage to the roof caused by water accumulation and strong winds, and the aluminized zinc layer effectively extends the roof's service life.
Insulation layer: 120mm - thick glass wool felt with a thermal conductivity of ≤ 0.04W/(m·K). It can not only insulate heat but also absorb sound, reducing external noise interference during aircraft take - off and landing, and creating a relatively quiet environment for aircraft maintenance and storage.
Waterproof layer: EPDM waterproof membrane is used. It has good flexibility, weather resistance, and waterproof performance, ensuring that the roof does not leak during long - term use and providing reliable waterproof protection for the hangar.
Dimension Specifications
Span: A variety of standard spans from 20 to 60 meters are provided, and super - large - span structures can also be flexibly customized according to the types of aircraft to be parked, the size of the airport, and operational requirements. This can meet the layout needs of different aircraft models, maintenance equipment, and aircraft movement spaces.
Length: There is no fixed limit and can be customized according to the actual length of the airport site. It can adapt to various - shaped and - sized airport areas, whether it is a regular - shaped or irregular - shaped site.
Height: The eave height ranges from 8 to 15 meters and can be adjusted according to the maximum height of the aircraft to be parked, the height of maintenance equipment, and the space requirements for aircraft lifting and movement. This ensures that there is sufficient space inside the hangar for aircraft entry and exit, maintenance operations, and the installation of large - scale maintenance equipment.
Special Performance Requirements
Fire - resistance Performance: The hangar is designed with a high - level fire - resistance rating. The main structural components are coated with fire - resistant coatings, and the enclosure materials have certain fire - retardant properties. In addition, a complete fire - fighting system is installed, including fire - sprinkler systems, fire - alarm systems, and fire - fighting equipment, to ensure safety in case of a fire.
Lightning - protection Performance: A professional lightning - protection system is installed on the hangar. Lightning rods and grounding devices are set up to effectively conduct lightning current into the ground, protecting the hangar and the aircraft inside from lightning strikes.
Load - bearing Performance: The floor of the hangar is designed to have a high load - bearing capacity. It can withstand the weight of large - scale aircraft, heavy - duty maintenance equipment, and the dynamic loads generated during aircraft movement. The floor material is a high - strength concrete with reinforcement, ensuring its long - term durability and stability.
Internal Facility Configuration
Aircraft Parking System: Custom - designed aircraft parking platforms can be provided according to the types of aircraft. They are equipped with precise positioning devices to ensure that aircraft can be parked accurately, which is convenient for maintenance and storage.
Maintenance Equipment Installation: The hangar is equipped with a variety of installation facilities for maintenance equipment, such as overhead cranes, hoists, and tool storage areas. These facilities can meet the needs of different aircraft maintenance operations, improving maintenance efficiency.
Ventilation and Lighting Systems: A large - scale ventilation system is installed to ensure good air circulation in the hangar, reducing the accumulation of harmful gases generated during aircraft maintenance. The lighting system uses high - brightness, energy - saving lighting fixtures, and can be adjusted according to different working areas and operation requirements to provide sufficient lighting for aircraft maintenance and inspection.
Installation and Service
Prefabricated Production: All components are prefabricated in the factory. Advanced production technology and a strict quality - inspection system are adopted to ensure high - precision and stable - quality components. This reduces on - site construction time, minimizes interference with airport operations, and reduces environmental pollution during construction.
Installation Cycle: Depending on the size of the hangar, the installation cycle of a 3000 - 20000㎡ hangar is generally 30 - 60 days. It is installed by a professional installation team with rich experience and professional skills. The installation team strictly follows construction specifications to ensure installation quality and construction safety.
After - sales Service: Provide a 10 - year structural quality guarantee, 5 - year enclosure - system quality guarantee, and lifetime maintenance consultation services. A 24 - hour after - sales response mechanism is established. Once customers encounter problems during use, the after - sales team will promptly provide technical support and solutions to ensure the long - term stable operation of the hangar and provide reliable support for aircraft storage and maintenance.
