At EZHONG, we are proud to supply cutting-edge machinery to global industry leaders. One of our key accomplishments is delivering an EZW11S-150*3200 Heavy Plate Rolling Machine to CCCC Third Harbor Engineering Co., Ltd., a renowned subsidiary of the CCCC Group, ranked among the world’s top 500 enterprises.
Founded in 1954, CCCC Third Harbor Engineering Co., Ltd. has evolved into a powerhouse in diversified civil engineering after over six decades of growth. This state-owned giant has spearheaded iconic projects like the Hong Kong-Zhuhai-Macao Bridge, the world’s most technically advanced bridge, and Asia’s largest offshore wind farm, the Huaneng East 300 MW Offshore Wind Power Project. With a dominant presence in China’s offshore wind market, the company continues to set benchmarks in national and global infrastructure.
The EZW11S-150*3200 Heavy Plate Rolling Machine, with its 150 mm thickness capacity and 3200 mm width, was chosen to address a critical need: efficiently rolling thick steel plates into precise cylindrical shapes for offshore wind tower components. This advanced equipment ensures high-strength, seamless structures, solving the challenge of meeting the rigorous demands of renewable energy infrastructure under harsh marine conditions.
This collaboration underscores EZHONG’s expertise in providing top-tier plate rolling solutions, supporting CCCC Third Harbor Engineering’s leadership in offshore wind and civil engineering projects. Contact us to elevate your manufacturing with our industry-leading machinery.
