1. Space Frame Structure: A Common Construction Method for Sports Halls Building
The space frame structure system used in steel structure sports halls has become the preferred solution for modern sports stadium construction due to its excellent mechanical properties and architectural aesthetics. Compared with traditional concrete structures, space frame structures have significant advantages in cost, design flexibility, and safety.
In terms of cost, the unit cost of the space frame structure is about 300-500 USD/㎡ (RMB 2000-3500 yuan/㎡), which is much lower than the 600-800 USD/㎡ of the concrete structure, and has outstanding economic advantages. This is due to the lightweight characteristics of high-strength Q355B steel, which not only greatly reduces the basic cost but also reduces construction waste through modular prefabrication. In addition, its rapid assembly process can shorten the construction period by 30%-50%, further saving labor and management costs, and the durability of steel also makes the subsequent maintenance costs only about 60% of the a concrete structure.
In terms of design flexibility, the space frame structure supports customization of various forms such as domes, flat plates, and free-form surfaces, perfectly adapting to different functional requirements such as basketball halls and swimming pools. Its modular characteristics allow for easy expansion or adjustment of the layout in a later stage, such as adding stands or adjusting the functional area division, while the bolt ball or welded ball node design is easy to disassemble and reassemble to meet future renovation needs.
In terms of safety, the three-dimensional grid system of the space frame structure can evenly distribute the load, the earthquake resistance can reach more than 8 degrees, and the wind resistance can withstand a typhoon of level 12. At the same time, the Q355B steel is galvanized or fire-resistant, which fully complies with the national fire and corrosion standards to ensure long-term and stable use.
Overall, space frame structures have become an ideal choice for modern sports venues with their lower construction costs, higher design freedom, and stronger safety performance. They are especially suitable for projects that require fast delivery, flexible layout, and long-term reliability.
2. The Core Advantages of a Steel Structure Building Sports Hall
1. Economic advantages
- Lower cost: The unit cost of a steel structure sports hall is about 300-500 USD/㎡, which is only 50%-60% of the traditional concrete structure (600-800 USD/㎡). This is mainly due to the high strength of steel, which makes the structure lighter, thereby reducing the foundation cost. In addition, modular prefabrication and on-site assembly technology have greatly reduced construction costs.
- Short construction period: As the components can be prefabricated in the factory and only need to be assembled on site, the construction period is shortened by 30%-50% compared with traditional concrete structures. For example, a 6,000㎡ steel structure sports hall can be installed in just 40 days.
- Low maintenance cost: Steel is highly durable, and the subsequent maintenance cost is reduced by more than 40% compared with concrete structures.
2. Design flexibility
- Large-span column-free space: Steel structure sports halls can easily achieve a column-free span of more than 120 meters, releasing more than 90% of the available area. They are suitable for basketball halls, swimming pools, and other venues with high space requirements.
- Diversified forms: supports customized designs such as domes, flat panels, free-form surfaces, etc., and can be matched with translucent glass or metal roofs, taking into account both natural lighting and technological lighting.
- Strong scalability: The modular design facilitates later expansion or functional adjustment (such as adding stands and partitions) to meet multi-functional needs.
3. Structural safety
- Excellent earthquake and wind resistance: The three-dimensional space frame structure has an earthquake resistance level of more than 8 degrees and can withstand a typhoon of level 12. The ductility and toughness of steel enable it to absorb energy through deformation during an earthquake, reducing the risk of collapse.
- Uniform load distribution: The spatial grid system efficiently transfers the load to the support points to avoid local stress concentration.
- Reliable fire and corrosion resistance: Q355B steel is treated with galvanizing or fire-retardant coating, which complies with national standards (such as GB50016).
4. Environmental sustainability
- 100% recyclable steel: The steel structure adopts high-strength Q355B steel, which can be fully recycled and reused, reducing 90% of construction waste and conforming to the concept of circular economy.
- Low carbon emission reduction: Compared with concrete structures, steel structures reduce carbon emissions by 57% over their entire life cycle, significantly reducing environmental impact.
- Integrated Photovoltaic (BIPV): The rooftop integrated photovoltaic power generation system can cover 20%-30% of the venue’s electricity demand annually, achieving energy self-sufficiency and reducing operating costs.
5. Energy-saving design optimization
- Rock wool sandwich panel exterior wall: Rock wool sandwich panel (sound insulation up to 65dB) is used to effectively isolate external noise, while having excellent thermal insulation performance and reducing air conditioning load.
- Intelligent ventilation and lighting: Combining skylights with intelligent ventilation systems optimizes natural airflow and light distribution, reduces air conditioning energy consumption by more than 18%, and improves indoor comfort.

Speed-up technology:
- BIM+3D scanning technology achieves millimeter-level installation accuracy
- The high-altitude bulk method can lift 120 tons per day
Q4. How many years can a steel structure sports hall be used? Is the maintenance cost high?
According to the latest industry data in 2025, the design life of a steel structure sports hall is usually 50 years, which can be extended to more than 60 years through hot-dip galvanizing (galvanizing layer thickness ≥ 80μm) and regular maintenance. The annual maintenance cost is about 0.8% of the construction cost (1.5% for concrete structures). The specific maintenance cycle needs to be adjusted according to environmental conditions. For example, coastal areas need to be treated with anti-corrosion once every 3 years, and inland areas once every 5 years. At the same time, it is recommended to use drone inspections (single cost 20,000 yuan) and implanted sensors to monitor corrosion conditions in real time to reduce 30% of overhaul costs. A typical case is that Jiaxing Fashion Sports Center uses self-healing coating technology to extend the anti-corrosion cycle to 8 years.
Q5. How large a span can a steel structure sports hall achieve? What innovative designs are there?
According to the latest engineering practices in 2025, the span capacity of steel structure sports halls has achieved a breakthrough. The current record for the longest single span is 320 meters (the Millennium Dome in the UK uses a hybrid tension system), and conventional space frame structures can reach 120-150 meters, while cable dome structures such as the Atlanta Stadium achieve an ultra-large span of 186×235 meters. The innovative design is mainly reflected in three aspects:
- Hybrid structural system: such as the prestressed chord dome of the Beijing University of Technology sports hall (93 meters in span, with a steel content of only 62kg/m²), which is lightweighted through hoop-cable tensioning technology;
- Intelligent construction technology: Shenzhen Bay Sports Center “Spring Cocoon” adopts a 38.7-meter cantilevered single-layer grid shell and uses 38 kilometers of digital prefabrication technology for bending and torsion components;
- Deformable structures: The 222-meter retractable roof of the Fukuoka Gymnasium in Japan and the cable-type aluminum alloy lattice shell of the Xiongan Sports Center (25% weight reduction) represent new trends in flexible structures.
The current technological limit has exceeded the theoretical span of 300 meters. The 274-meter cable net structure and 3D printed nodes (accuracy 0.1mm) of the Lusail Stadium mark the next generation of development. It should be noted that the actual span needs to be evaluated based on load, geology, and cost (the 320-meter dome cost 758 million pounds).
Q6. Does the initial cost of a steel structure sports hall include all hidden costs? How to avoid additional costs later?
A: The basic cost includes core costs such as steel, processing, transportation, and installation, but attention should be paid to regional variables (such as a 15%-20% increase in labor costs in plateau areas and fluctuations in sea transportation in coastal areas) and special process requirements (such as the in-depth design fee for curved grids). It is recommended to simulate construction difficulties in advance through BIM full-process modeling, lock component sizes and installation sequences, and reduce on-site changes; choose a modular solution with a factory prefabrication rate of ≥95% to avoid rework costs caused by on-site errors in traditional processes.
