Nanjing Daji Steel Tower Manufacturing Com., Ltd was founded in 1997, is specialized in producing both angle and tubular structures of transmission line towers at all class of voltage, substation structures, as well as tele-broadcasting tower and microwave communication tower.

Nanjing Daji Steel Tower Manufacturing Com., Ltd covers an area of  510,000 square meters, with a floor area of 200,000 square meters, which is divided into seven functional region, including angle steel tower fabrication zone with annual production capacity of 400,000 tons，tubular tower fabrication zone with annual production capacity of 150,000 tons，hot-dip-galvanization fabrication zone with annual capacity of 600,000 tons，technology center，raw materials storage house，office building of administration and living service area.

According to the guiding principle of Large scale production，standardized management and internationalized operation, Nanjing Daji Steel Tower Manufacturing Com., Ltd put forward the allocation of resources and operation management.

The company has already acquired the manufacturing license issued by both the P.R.C. and General Administration of Quality Supervision, Inspection and Quarantine of the P.R.C. According to ISO9001，ISO14001 and OHSAS18001, Quality，Environment and Occupational Health and Safety management system have been set up, and continue efficiently.

Masses numerical control devices and processing automation equipments have been adopted, almost realized the processing automation; different sizes of angle would be galvanized under different technics by four hot-dip-galvanization lines integrated with the latest high-tech in the current world, meanwhile production capacity and work efficiency are highly enhanced; self-developed patented technology of five elements galvanization(zinc，aluminum and rare earth alloy) lead the galvanizing quality to first class in the world. Complete quality management system and quality detection methods realize the multidirectional quality control from raw materials to production process.      Through comprehensive treatment with acid fog，smoke and dust，waste water and relative other industrial pollutant, the emission reaches the national standard. Through the application of rain collecting and purifying circulation system，the adopting of high performance and low energy consumption facility, comprehensive energy consumption are obviously reduced compared with the traditional production mode, moreover ecological benefits are very obvious.   

Nanjing Daji Steel Tower Manufacturing Com., Ltd is graded as "AAA level credit enterprise" by the third party every year, was honored as "Enterprise with excellent credit standing" by China National Administration for Industry & Commerce; has won the title of "Jiangsu Provincial famous brand"，"New Product at State Level" etc.
