With the construction area of 16,000 square meters, the steel structure comprises the stadium and training center. The roof steel structure uses the orthogonal spatial double-sided mesh shell structure. The multi-point support is on the top of lower concrete structure. The mesh nodes are bolt ball grid nodes and welding ball nodes. The outer metal maintenance for this project uses the cleansing galvanized standing seam roof as the waterproof roof. The roof uses the curved and fan-shaped plate. The maximum elevation of roof is 28.8 meters.
