After five years of planning and nine years of construction, the Hong Kong-Zhuhai-Macao Bridge with a total length of about 55 kilometers was officially opened on October 24. The Hong Kong-Zhuhai-Macao Bridge spans the ocean, connects Hong Kong to the east, and connects Zhuhai and Macau to the west. It is the longest sea-crossing bridge in the world. Its construction will greatly shorten the time and space between Hong Kong, Zhuhai and Macau, driving from Hong Kong. To Zhuhai and Macau, it will be shortened from 3 hours to 45 minutes, including the western part of the Pearl River Delta will be included in Hong Kong's 3-hour drive.
The design life of the Hong Kong-Zhuhai-Macao Bridge is 120 years, which makes the project put forward higher technical requirements from design to construction. Tiantai welding consumable wire TWE-711, TWE-711Ni and TM-70C won the bid for the Hong Kong-Zhuhai-Macao Bridge project with stable quality and good performance. The Hong Kong-Zhuhai-Macao Bridge Project Zhongjianghai Direct Ship Channel Bridge, the Kyushu Waterway Bridge's pylon and steel box girder, and most of the 110-meter span navigation bridges use the flux-cored wire of Tiantai Welding Materials.
