Nanjing Daji Steel Tower Manufacturing Co., Ltd. was established in 1997 and is a professional enterprise that produces various voltage levels of transmission line towers, communication towers, steel pipe towers, substation structural supports, and other products. The company is located in Qiaolin Industrial Concentration Zone, Pukou District, Nanjing, covering an area of approximately 670000 square meters. With an annual production capacity of 400000 tons of angle steel towers, 150000 tons of steel pipe towers, and 600000 tons of hot-dip galvanizing, it is currently one of the most influential and internationally advanced tower manufacturing enterprises in China.

The company is a national high-tech enterprise, a "specialized, refined, unique, and new" small and medium-sized enterprise in Jiangsu Province, and a "green factory" in Jiangsu Province. The company has been recognized by the Jiangsu Provincial Enterprise Technology Center and the Nanjing Engineering Technology Research Center, and has a professional technical research and development team, providing solid support for the company to maintain industry-leading research and development capabilities in new products, new processes, and equipment and fixtures. Currently, it has obtained nearly 40 national patents, and its technical research and development strength has been widely recognized. I have participated in the revision of multiple industry and national standards, including DL/T1401-2015 Technical Conditions for Manufacturing Steel Pipes for Transmission and Transformation Steel Structures, YB/T4835-2020 Hot Rolled Weather resistant Angle Steel for Iron Towers, DL/T646-2021 Technical Conditions for Manufacturing Steel Pipe Structures for Transmission and Transformation, GB/T2694-2018 Technical Conditions for Manufacturing Transmission Line Iron Towers, and GB/T2694-2018 Technical Conditions for Manufacturing Transmission Line Iron Towers. The "Five Element Alloy Galvanizing" technology developed by the company has been verified by the Institute of Metal Corrosion, Chinese Academy of Sciences in terms of physical and chemical indicators. Its corrosion resistance is more than twice that of traditional processes and meets the requirements of national and international galvanizing standards such as the United States, the United Kingdom, and the European Union. The core technology of galvanizing is at the forefront of the world. The company's products are sold in all provinces and regions in China except Taiwan and Macau, and exported to more than 60 countries in Asia, Africa, Europe, and the United States.
