Railroad building

Industry profile

As the essential national infrastructure and means of transportation for the masses, railway is the main artery of national economy and plays a vital role in China's economic and social development. It conforms to our national conditions and well serves the massive flow of regional and urban and rural personnel and materials. Over the past more than three decades since the reform and opening up, China has been extending its railway at an actual annual growth rate of over 9%. During the 13th Five-year Plan period, China is to speed up the high-speed railway coverage over more than 80% of its major cities. With the steady increase of domestic investment and the accelerated implementation of "going out" strategy, railway construction is ushering in new historic opportunities for development.

Products application

Steel bars for pre-stressed 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 applied in railway viaduct pier prestressed member, such as in the international has a very broad market.

R&D

  • ● 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.

Honor&Certificate

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.

Partner

  • ● 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.
