The creative design of the National Indoor Stadium resembles an unfurled traditional Chinese folding fan. The Chinese say that a folding fan holds a deep level of cultural detail; it is a component of Chinese culture. And the National Indoor Stadium embodies the charm of traditional Chinese architecture.
The steel roof truss of the National Indoor Stadium stretches 144 meters tall and 114 meters wide. The frame is composed of 14 steel beams weighing a total of 2,800 tons.
According to assistant general manager Shen Yongshan of Guoao Investment, the owner of the stadium, this is the longest spanning indoor, bi-directional truss string structure in China at present.

The steel roof truss was installed using nine robots. The construction workers relied on the robots to move and join the steel truss beams.
