High tensile strength low relaxation 1x7 PC Strand

1x7 PC Strand includes a straight central wire, called a core wire around which are spun six wires in one layer.The outer wires is tightly spun around the central wire with a lay length.The diameter of the central wire is greater than the diameter of the outer helical wires. Our factory could accord to different standards to produce this product.
