Prestressed Material
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.
