Hangxiao Steel Structure is a top-tier municipal engineering steel structure manufacturer, focusing on large-span space structures for stadiums, airports and transportation hubs. Our column-free steel stadiums (Model: HXSS-12) are designed for international sports events, featuring 100m+ clear spans and 90% fewer pillars to deliver unobstructed spectator views. Adopting Q420B high-tensile steel and modular prefabrication technology, the product meets FIFA/AFI standards, with excellent seismic resilience, fire resistance and weather adaptability. It is the ideal choice for building professional stadiums, airport terminals and high-seismic transportation hubs.
Specification Item | Details |
Model | HXSS-12 |
Brand | HXSS |
Core Material | Q420B high-tensile steel (yield strength ≥420 MPa) |
Max Clear Span | 50–120 meters (100m+ for stadium applications) |
Prefabrication Accuracy | 95% factory prefabrication, ±1.5mm joint tolerance |
Load Resistance | Snow load: 2.5 kN/m²; Wind speed: 45m/s |
Seismic Rating | 8.5-degree seismic resilience |
Fire Protection | 3-hour fire-resistant intumescent coating |
Corrosion Protection | 350g/m² galvanized coating (for airport/transport hub use) |
Recyclability Rate | 98% recyclable materials |
Lifespan | 100-year design lifespan |
100m+ column-free spans meet the standards of FIFA and AFI, creating unobstructed viewing angles for every spectator seat. A 60,000-seat stadium project in Berlin adopted this technology, reducing the number of pillars by 90% and winning high praise for its excellent viewing experience. The lightweight steel structure cuts foundation costs by 30% and shortens the construction period by 18 months compared with traditional projects.
Modular steel trusses realize rapid on-site assembly. A 25,000-seat stadium in Qatar completed its 150m roof installation in just 9 months, 50% faster than conventional methods. BIM technology optimizes component design, ensuring 95% prefabrication accuracy and avoiding on-site modification delays.
The energy-dissipating steel nodes of the space frame structure achieve 8.5-degree seismic resilience, absorbing 150% more energy than concrete structures in earthquake simulations. The 3-hour fire-resistant coating protects critical structural parts, while the 350g/m² thick galvanized coating is resistant to de-icing chemicals, reducing maintenance costs by 40% for airport and transportation hub applications.
The retractable ETFE-steel roof can switch between open-air and climate-controlled modes in 15 minutes, adapting to changes in weather conditions. This design increases the annual available event days of stadiums by 25% and boosts event revenue significantly. Post-construction modifications cost 45% less than traditional concrete stadiums, supporting functional upgrades as needed.
The 100m+ clear spans meet FIFA/AFI competition standards, suitable for building large-scale football stadiums, indoor arenas and multi-functional sports centers, hosting international competitions and large-scale cultural performances.
Steel’s lightweight advantage supports 1.5km-long roof spans without intermediate supports, as applied in Istanbul Airport. BIM-driven modular units achieve 3 floors/month assembly speed, and integrated solar panels generate 15% of the terminal’s energy needs.
The ductile steel structure provides 8.5-degree seismic protection, suitable for railway stations and metro hubs in earthquake-prone areas. Prefabricated steel platforms reduced Tokyo Metro’s station retrofit time from 18 to 7 months, improving infrastructure operation efficiency.
