Large cast steel nodes are widely used in all kinds of steel structures with their good mechanical properties and modeling flexibility. This technology mainly solves the problem of the control and dimension and precision detection of the force, shape and flow injection process in steel structure engineering. The good mechanical properties and modeling flexibility of cast steel nodes meet the requirements of architectural modeling and structural stress. Zhengzhou international convention and exhibition center, is a work highly acclaimed by domestic and foreign experts. It is the "application technology of large cast steel joint" that supports this "crown of world city planning and design". 2200 tons of cast steel pieces, nearly 36 tons of the heaviest piece, made JINGGONG  the model of this field. The technology has also been successfully applied to projects such like the Guangzhou opera, King Abudauaziz International airport of American standard in Jeddah in Saudi Arabia, Metro Station of Tuas West Extension in Singapore of European standard, and the Hong Kong passenger clearance building for HK-Zhuhai-Macao Bridge, and so on.
