At EZHONG, we are thrilled to announce the successful sale of our **EZW11SY-200/4500 Heavy Plate Rolling Machine** to Lamprell, a leading UAE-based provider of engineering and fabrication services for the renewable energy and oil & gas sectors. Renowned for its expertise in constructing wind turbine foundations and offshore structures, Lamprell chose our advanced machinery to enhance its wind tower manufacturing capabilities.
Lamprell, headquartered in the UAE with primary facilities in Hamriyah, has over 45 years of experience delivering high-quality projects globally. As a key player in the offshore wind market, the company has invested heavily in renewable energy solutions, including a state-of-the-art production line for wind substructures, aligning with the UAE’s Energy Strategy 2050 to boost renewable energy contributions.
Our **EZW11SY-200/4500 Heavy Plate Rolling Machine**, designed for wind tower production, tackles a critical challenge: precisely rolling thick, heavy steel plates into large cylindrical sections. With a 200 mm thickness capacity and 4500 mm width, this fully hydraulic machine ensures accurate pre-bending and seamless forming, addressing the need for durable, high-strength wind towers capable of withstanding harsh offshore conditions.
This collaboration highlights EZHONG’s leadership in delivering robust plate rolling solutions, enabling Lamprell to meet rising demand for renewable energy infrastructure. Contact us to learn how our equipment can drive your success in wind tower manufacturing.
