Recently, the delivery ceremony of the "Hengtong Haiyue" large wind power installation platform was held in Nantong. In this eye-catching project, the 177.8mm extra-thick rack steel was all supplied by Xianggang. Xianggang once again demonstrated its outstanding strength in major projects.

The "Hengtong Haiyue" large wind power installation platform has a 1,600-ton pile-circling full-rotation super-strong crane. It is the leading fourth-generation self-propelled and self-elevating deep-sea large wind power installation platform in China. Extra-thick rack steel is mainly used in key structures such as wind power installation ships and self-elevating offshore platform pile legs. It has the characteristics of high weldability, high density, high strength, and toughness. Xianggang has overcome the difficulty of producing extra-thick rack steel by continuously optimizing the technical parameters of key links such as smelting and rolling.

In recent years, Xianggang has insisted on technological innovation and promoted the product structure adjustment to the high end of the value chain. After completing the mass production and delivery of 177.8mm extra-thick rack steel, Xianggang has developed extra-thick and extra-heavy rack steel plates with a maximum thickness of 210mm and a maximum unit weight of 33 tons and has obtained certification from classification societies of 6 countries. This is the maximum thickness currently certified in China.
