PROJECT HIGHLIGHTS & ADVANTAGES

Long-Span Breakthrough
The large-span space frame structure is both lightweight and robust, successfully achieving a 120-meter column-free clear span. This creates a spacious and well-lit interior that can be flexibly adapted for sporting events, large-scale performances, and exhibitions.
Efficient Construction
A combined construction method of segmental prefabrication and overall lifting is employed. Ground-level assembly ensures high construction quality and precision, while multiple work fronts operate simultaneously, significantly improving efficiency and minimizing weather-related delays—ultimately shortening the overall construction timeline.


Safety and Reliability
Specially designed multi-point seismic joints act as the building’s “reinforced hinges,” effectively withstanding seismic events up to intensity 8. This ensures occupant safety and enhances the overall reliability and lifespan of the structure.
Energy Efficiency and Environmental Sustainability
The roof incorporates high-performance thermal insulation materials that retain indoor heat during winter and block external heat in summer, significantly reducing air conditioning energy use. This not only achieves energy savings and environmental benefits but also lowers long-term operational costs.


Integration of Aesthetics and Functionality
The streamlined roof design seamlessly integrates with the architectural style of the stadium. Through aerodynamic design, it effectively guides airflow to reduce wind loads—realizing a perfect balance between aesthetics and functionality.
