The Haihe Super Large Bridge on the Tianjin-Jishan Expressway, which won the “Luban Prize” for the 2016-2017 China Construction Project, consumed 12,000 tons of steel in its structure. The steel was exclusively provided by Shougang Shouqin Corporation.

The Haihe Super Large Bridge on the Tianjin-Jishan Expressway adopts a steel truss structure and requires high quality steel plate materials and welding technology. The project headquarters inspected in many ways. The Q345qD bridge steel plate produced by Shougang Shouqin Corporation has high strength and good low temperature toughness, weldability and anti-seismic property (low yield ratio). All aspects of performance have the conditions of use. Shouqin Corporation was finally determined to be the bridge steel plate supplier.

In recent years, with the rapid development of China’s transportation industry, bridge construction has embraced rapid development. Shouqin Corporation seizes the opportunity to focus on R&D and market development of bridge steel products, and establishes a product development model combining production, sales, and research to achieve seamless integration of various technology-oriented professions and continuously improve product development, market development efficiency and consumer services. At present, it has successfully developed the new generation of 370, 420, and 500MPa grade high-performance bridge steel for TMCP + tempering, 345 to 420MPa grade weather-resistant bridge steel, 420 to 460MPa grade European standard high-performance bridge steel, and Q370qD+316L stainless steel composite plates, which are widely used in the construction of large bridge projects at home and abroad. The new generation of 370-420MPa grade high-performance bridge steel developed by Shouqin Corporation has achieved mass production of Q345q, Q370q and Q420q series under the GB/T714 system; the steel plates for bridge structures of the American Standard A709 and European Standard 10025 are used in the bridge projects in South America, Southeast Asia, Europe and other regions, achieving good economic and social advantages. In the construction of the Haihe Super Large Bridge on the Tianjin-Jishan Expressway, Shouqin Corporation overcame the difficulties of the long-span low carbon equivalent, low yield ratio, steel plate shape, impact toughness, welding performance of steel plate, and short delivery time to supply the bridge steel used in this project outstandingly according to the progress of the project and was highly recognized by China Railway Major Bridge Engineering Group Co., Ltd. and users.
