According to Cosco shp sg, the Shenzhen-Zhongshan Bridge Tunnel officially opened on June 30th. As an important participant in the Shenzhen-Zhongshan Bridge Tunnel project, Cosco shp sg's national specialized, special, and new 'little giant' enterprise, Cosco Guangxi, provided nearly 2700 tons of 'epoxy glass flake' heavy-duty anticorrosive coating for the 320,000-ton steel shell of the immersed tube tunnel, giving the underwater tunnel a solid 'armor'. This is not only the largest steel structure project contracted by Cosco Guangxi so far, but also the project with the largest amount of epoxy glass flake paint used.
