PC Steel Bar
PC Steel Bar
Our company isa professional producer of the pre-stressed steel bars and glossy pre-stressedsteel bars for high-speed railway sleepers. The PC steel bar is a reinforcingbar. Compared with the pre-stressed strand and pre-stressed wire, it has alarger diameter, better straightness and spot weldability. Its manufacturingprocess calls for better production equipment, testing method, and inspectiontechnology.

Our company owns 6 pre-stressing bar production lines. The quality of itsequipment can meet the international standards. Its product features highdimensional accuracy. The surface of the PC steel bar can be supplied withspiral grooves or smooth finish. These two kinds of products have similarspecifications and mechanical performances. Products with a diameter of 6.1mm, 7.1mm, 9.0mm,or 10.7mm canhave the tensile strength of 1230MPa, 1420MPa, 1570MPa, or 1670MPa. The 7.4mm, 9.2mm, 11.0mm,and 13.0mmdiameter bars can achieve 1230MPa, 1420MPa, and 1570MPa tensile strength withthe relaxation loss at 1000 hours being under 1.5%.
