The Chengdu Tianfu International Airport Terminal is a premier mega-aviation hub in Western China, renowned for its iconic “Sunbird” architectural form. Featuring an expansive long-span spatial pipe truss system and a complex curved roof canopy, the project utilized over 130,000 metric tons of high-strength structural steel. This megastructure demonstrates industry-leading engineering capabilities in heavy-duty spatial grid assembly, precision pipe bending, high-precision factory pre-fitup, and rigorous 100% NDT-certified welding quality control.
