The Last Stay Cable Of The Hutong Yangtze River Bridge Was Officially Completed! 2000MPa Grade Cable Steel For The World's First Application
Produced by CITIC Special Steel Co., Ltd., the world's first public-rail dual-purpose cable-stayed bridge – the cable-stayed cable for the construction of the Hutong Yangtze River Bridge was completed, which marked the 2000MPa bridge cable for CITIC special steel supply. Realized the world's first successful application.
At present, the super-long span bridges of more than one kilometer are all cable-stayed bridges or suspension bridges. The investment in large-scale bridge construction is large, and the service environment is complex. There are strict requirements on the strength index, torsion index, fatigue performance and corrosion resistance of the bridge cable.
The 2000MPa grade bridge cable steel supplied by CITIC Special Steel is applied to the Hutong Yangtze River Bridge. It not only realizes the world's first application of 2000MPa grade bridge cable steel in extra large bridges, but also realizes the first domestic adoption of Φ7.0mm 2000MPa. The breakthrough of the grade cable stays marks a new leap in the construction of bridges in China, and the material field for bridge construction has entered a new era of vigorous development.
