Bridge engineering

Industry profile

China has a large territory with crisscrossing waterways. Among them are the famous Yangtze, Yellow and Pearl rivers which have witnessed the extraordinary achievements in China's bridge construction since ancient times. With the development of China's economy, the demand for passenger and freight road transport will continue to rise rapidly. The development of road bridge will effectively draw closer the distance between different places.

Products application

Steel bars for the prestressed concrete (P.C Steel bar) because it has high strength and toughness, low relaxation, and the grip of concrete is strong, good weldability and upset, save material, has been widely used in prestressed concrete components such as transmission line pole, has the very broad market.


  • ● On-line automatic straightening derusting, cold drawn nick, online heating using high frequency induction heating furnace (secondary quench heating and one tempering heating), heat treatment cooling water temperature automatic control, water-crossing heat treatment, online antirust processing, and SVG resonance elimination + reactive power compensation of finished products, and other automatic production lines composed of advanced technology and equipment. We have realized the automatic production model of energy conservation and environmental protection, which is the first production equipment of this kind in China; at the same time, the quality of products is ensured to be in the leading position domestically.
  • ● The sea piles in production are generally of large diameters of 800-1,200 mm, and the largest is even up to 1,500 mm, so customers have to choose prestressed steel bars of 14 mm or more. Upon concerted efforts of branch departments, we have produced a sample for trial by our customers. Until now, our domestic counterparts of steel bars haven't produced this kind of products.1200mm
  • ● PC steel bars are automatically sprayed with antirust paint in the surface. Rust products for the rainy season have been developed, which plays a leading role in China.


High strength prestressed concrete steel bars has been rated as “High & New Tech Product in Jiangsu Province”, “Famous Brand Product of Jiangsu Province,By ISO 9001:2008 quality management system, ISO 14001:2004environmental management system and OHSAS 18001:2007 occupational health and safety management system certification. And get Korea KS Certificate.[View more certificates]


  • ● Cooperative project has been conducted with the Materials Science and Engineering College of Jiangsu University of Science and Technology and the East China Branch of the General Iron and Steel Research Institute to make technological breakthrough
  • ● We have been cooperating with Daewoo of South Korea, Sany Heavy Industry, and China Shipbuilding Industry Corporation to research on and develop steel for deep sea oil wells and platforms.
  • ● NJB400 bulb flats developed with Zhoushan COSCO fill the domestic blank and end the history of relying on imports only.
