Zhangjiagang Xinhua Pre-stressed Steel strands Co., LTD is a joint-venture enterprise by Jiangsu Shagang Group Co., LTD and Xinyu Iron and steel Group Co., LTD, which is dedicated for pre-stressed steel strands production. The existed four production lines are all equipped the imported machines, the specifications cover 1×7－Φ9.50mm and 1×7－Φ21.6mm, annual output is 160 thousand tons. Pre-stressed reinforcement concrete steel strand and called pre-stressed strand for short, it has the features of high strength and less relaxation. Since the pre-stressed strands are applied into the concrete, the loaded ability of the structure will be improved and the fracture faces will be reduced as well, it can help to save 30-40% rebar and 40% concrete; also elongate the life time of pre-stressed concrete parts, buildings’reliability and stability are all improved. Meanwhile the extension on span length can help to reduce the columns for the space availability.

Zhangjiagang Shagang Jinzhou Steel Pipe Co., Ltd has a JCOE process large diameter LSAW pipe production line. JCOE adopts the process of asymptotic bending forming, so stress can be even distributed and pipe shape kept well; the treatment of pre-welding +finished-welding can guarantee the good welded seam quality; the straight welded seam can be made nondestructive inspection conveniently; the expanded diameter treatment to pipe can minimize and even distribute inner stress，it can prevent the stress corrosion crack and keep size in high precision; Since various specifications they can produce, nearly all the size within the scope can be made, not only the small diameter thick walls also the big ones. Since put into production, it has supplied the prime pipes to many clients globally, such as USA, Chili, Venezuela state oil and natural gas Company, Sinopec project on the natural gas transmission from Xichuan to East China, PetroChina project on crude oil transmission piping between China and Kazakhstan, Central Asia Natural Gas pipe, Chad Piping project the second phase, Weizhou Natural Gas piping project the second phase, Shanxi Jingbian to Xi’an natural gas project the third phase, Jinzhou to Zhengzhou petroleum pipe line project, Zhenhai petrochemical project, Fujian Xianglu petrochemical project, Dalian Hengli petrochemical project, Steel Structure of Tianjin Train Station, Russian Bridge project and so on.
