Product details 


The Clear-Span Steel Stadium Building for Large-Scale Events is designed to host high-capacity crowds for sports, concerts, and exhibitions. Its long-span steel truss system (up to 200m clear span) eliminates interior columns, ensuring panoramic sightlines for up to 50,000 spectators. The retractable ETFE membrane roof allows natural light during daytime events while providing weather protection, with a 30-minute automated closure system for sudden rain.


Constructed from hot-dip galvanized steel (S355JR grade), the structure resists corrosion in coastal or high-humidity regions. Acoustic-optimized composite panels (NRC 0.85) line the interior to enhance sound quality, while integrated LED lighting grids support dynamic event setups. Reinforced steel decks (load capacity: 5 kN/m²) accommodate stage equipment, VIP lounges, and concession stands. The stadium’s modular seating tiers can be reconfigured for different event types, from soccer matches to trade shows.

Key features include hurricane-resistant bracing (wind resistance: 70 m/s), fire-rated escape corridors (EI 60 certification), and solar-ready roof panels for sustainable energy integration. Compliant with FIFA and IAAF standards, this stadium is ideal for cities aiming to host international tournaments or cultural festivals.
