The predecessor of Anshan Yuanda Power Grid Engineering Co. is Anshan Steel Tower R&D Center. For many years we have been committed to research and development of low-cost and high-performance poles and tower products. By absorbing advanced technology from foreign countries and continuous improvement and testing, we have obtained a major break-through in improving the performance of new materials and improving molding process. At the same time, we successively developed composite poles and towers, cement-based composite material poles, ultra high performance concrete(UHPC) poles and other products. They are upgrade products with high quality and low cost compared to traditional products, such as concrete poles, steel poles, towers etc. Until now, our company has won more than 10 patents. We can have effective protection for new products in structural form, production processing and product equipment, so it can ensure us the leading position in the relative technology.
