The Hong Kong Zhuhai Macao Bridge, which attracts worldwide attention, is officially opened on 24th, Oct., 2018. In the construction of this super project, known as the "Mount Qomolangma" in the bridge circle, more than 21,000 tons of key steel plates used by the main body of the bridge are made of BBN steel and Valin Group.

As the longest cross sea bridge in the world, the Hong Kong Zhuhai Macao Bridge is the first difficult in China to manufacture steel structures. The steel structure is the "backbone beam" of the bridge. Its life directly affects the quality of the bridge. The design life of the bridge is far longer than that of the general bridge. It is expected to reach 120 years. It is also required to be able to withstand typhoons of magnitude 16, earthquakes of magnitude 8 and collisions of 300,000 tons of huge wheels. The requirements for the steel plate quality are extremely strict.

BBN Steel and Valin Group provide more than 21,000 tons of high-quality steel plates for the main body of Hong Kong Zhuhai Macao Bridge. Each steel plate meets the requirements of 4.5 meters ultra-wide size, and flatness difference can not exceed two millimeters.

BBN Steel and Valin Group Steel Plates are mainly used in bridge deck and pipe pile, which are the key parts of the bridge. It requires high quality of steel. It has special requirements in toughness, flatness and service life of the bridge.
