Original Project Detail

Developed as the new venue for the Bund Conference E-sports Arena, this project features a high-performance, large-span steel structure system designed and executed in accordance with international standards. The building adopts a partially two-story portal-frame configuration with a maximum clear span of 45 meters, achieved without traditional trusses. Instead, high-strength H-section steel members and specialized fabrication and reinforcement techniques were employed to control deflection and ensure long-term structural stability. With total steel consumption of approximately 800 tons, the project represents a technically demanding application of heavy steel in an urban core setting. As the steel structure supplier, we delivered a durable, precision-engineered system within one month, accelerating the construction schedule while ensuring exceptional safety, reliability, and load-bearing performance.
