The Siyang Olympic Sports Center Gymnasium is a signature civic landmark featuring an advanced long-span spatial steel structure system. Designed to host major sports events and cultural activities, the venue utilizes a custom-engineered spatial pipe truss canopy that achieves a grand, column-free interior space. The project showcases specialized capabilities in long-span pipe truss fabrication, high-precision 3D pipe bending, rigorous factory pre-assembly, and strict 100% NDT-certified welding quality control for public infrastructure.
