Structural Type
Truss Structure: It features a well-defined load distribution and is suitable for large-span hangars. It effectively transfers roof loads to the foundation. Common examples include triangular trusses and trapezoidal trusses.
Grid Structure: This spatial load-bearing system offers excellent integrity and provides a large, column-free space for aircraft parking and operations. Its diverse node configurations accommodate diverse architectural styles.
Portal Frame Structure: This economical and practical structure features rapid construction and is particularly suitable for small and medium-span hangars. Load-bearing requirements can be met through the rational design of beam and column dimensions.
Steel Selection
High-strength structural steel, such as Q345 and Q390, is typically used to ensure sufficient strength and stability to withstand aircraft loads, wind loads, and snow loads.
For corrosive environments, such as coastal areas, weathering steel or steel with special anti-corrosion treatments is used to enhance the structural durability.
Span and Height
Spans typically range from 20 to 100 meters to accommodate the parking and access requirements of different aircraft types. Some large civil aviation hangars have even larger spans, capable of accommodating multiple large aircraft simultaneously. The height is determined based on the aircraft type and maintenance requirements, generally ranging from 8 to 20 meters to ensure sufficient clearance for aircraft and sufficient operating space for maintenance equipment. Product Advantages: Large Space Creation: Ability to create an ultra-large, column-free space, providing ample space for aircraft parking, maintenance, and overhaul, and facilitating the dispatch and use of aircraft and various support equipment. Safe and Reliable Structure: Through precise mechanical calculations and design, and the selection of appropriate structural forms and steel materials, the hangar structure can withstand heavy loads and exhibit excellent seismic and wind resistance, ensuring safety in a variety of harsh natural conditions and safeguarding the aircraft and related facilities. Short Construction Period: Certain structural forms, such as portal frames and prefabricated trusses, can be prefabricated in the factory, enabling rapid on-site installation. This effectively shortens the construction period, enabling airport operations to be met as quickly as possible, and minimizing the impact on normal airport operations during construction.
Selling Points for Buyers
Customized Design: Based on factors such as the buyer's hangar's intended use (type of aircraft, whether maintenance operations are performed), site conditions (geology, surrounding environment), and budget, we provide personalized hangar structural design solutions to ensure they fully meet the buyer's actual needs.
Quality and Maintenance: Design and construction strictly adhere to international and industry standards, and strictly control quality throughout the entire process, from raw material procurement to project delivery. We also provide comprehensive maintenance solutions and after-sales service to extend the hangar's service life and reduce long-term operating costs.
Ancillary Services: In addition to the hangar structure itself, we also provide related supporting services, such as design and installation recommendations for roof waterproofing systems, ventilation and lighting systems, fire protection and insulation systems, etc., creating a one-stop solution for buyers and facilitating the overall progress and management of the project.
