Steel Structure Factory | Hebei Medical Industry Park

As an industry-leading full-process prefab steel building manufacturer, HNYJJZKJ Steel Structure has ploughed deeply into the field of transportation technology facilities for more than 20 years. Relying on the high-performance characteristics of Q355B S355JR A572 SM490A grade high-strength steel, coupled with continuous technological innovation, HNYJJZKJ Steel Structure reconstructs the space of the aviation hubs and provides global customers with a modernized terminal building system that integrates high efficiency and intelligent green building, from the design of the steel structure, processing, manufacturing, construction, to the subsequent maintenance during the use of the building. We create a modernized terminal building system that is highly efficient, intelligent, and green.

1. What types of steel structures can be used in airports terminal and public facilities?

Frame structure (airport terminal, hangar)

The frame structure is like a huge three-dimensional spider web woven with countless steel rods. The mature design can evenly distribute the weight of the entire roof to each rod. The advantage of this structure is that it can easily span hundreds of meters without any column support. At present, the largest hangar in Asia is made of frame structures, with a column-free span of 404 meters, which can accommodate 12 aircraft, including 2 Airbus A380 and 3 Boeing 777, for parking and maintenance. After the modular prefabricated components are processed in the factory, they are quickly assembled on site with bolts, which can shorten the construction period by 30%. It is particularly suitable for the rapid construction needs of large-scale public buildings such as airports.

Cost: The unit cost of the frame structure is usually 300-500 USD/㎡. With its advantages of good spatial force performance, light weight, and high rigidity, it has been widely used in large-scale terminal buildings, exhibition centers, and industrial plants. Especially in large-span space construction projects, its economic and structural performance advantages are more significant.

Large-span space truss (terminal building, Business aircraft apron)

By adopting the combination system of steel joist and H-beam, it realizes the column-free space with large span (the biggest technological breakthrough of XTD steel structure reaches 140m single span without support), which meets the heavy load demand of the central hall of the large hub airport and the baggage sorting center, etc. The prefabricated steel structure’s on-site assembly time is 30% shorter than the traditional process. The on-site assembly period of prefabricated steel components is 30% shorter than the traditional process, and the column-free design increases the effective use area by 25%, which can carry loads of more than 5t/m2 (e.g., baggage conveyor system, large-scale ceiling equipment). Equipped with intelligent lighting, skylight, and a three-dimensional ventilation system, energy consumption is reduced by 18%.

Cost: the cost of a single party is about 220-300 USD/㎡, widely used in the main terminal building of international airports.

Steel Structure Multi-storey Comprehensive Building (Stereo Garage, Commercial Center, Business Office Building)

Core Advantage: BIM-based full-process design of the three-dimensional transportation hub, factory prefabricated modular units assembled quickly on-site, the construction cycle of the main structure below 6 floors takes only 60 days. Vertical space utilization rate is increased by 300%, and check-in halls, waiting bridges, commercial complexes, and underground transportation connections (e.g., subway and high-speed railway interchange) can be integrated. Adopting an anti-continuous collapse design, the seismic grade reaches 8 or above, supporting an intelligent simulation system, realizing the whole process of digital operation.

Cost: The cost per square is about 280-380 USD/㎡, suitable for air-high-speed rail intermodal transportation hubs.

Standardized portal frame (small terminal)

Core advantages: prefabricated production using American standard A36 steel or equivalent national standard components to realize the “factory manufacturing + on-site assembly” mode. The standard span design (20×30 meters, 30×40 meters, 30×50 meters) forms a column-free waiting space, and the steel structure processing accuracy reaches ±2mm, saving 30% of steel and reducing 40% of the initial construction cost. The modular structure supports the extension of the corridor or the expansion of the boarding bridge in a later stage, and the check-in area, security inspection channel, and commercial area can be flexibly divided inside. The earthquake resistance is 8 levels, and the wind resistance level is 70 meters/second, meeting the safety standards of hub airports Structure. (Compared with traditional terminal buildings)

Cost: (Traditional cost) The unit cost is about 150-220 USD/㎡, which is suitable for the construction of small and medium-sized airports and satellite halls.
