Strand Lay

In a strand construction with several layers of wire of the same diameter the different layers cross each other (cross lay). In an strand construction with unequal wire diameters the layers of wires lie parallel to each other (equal or parellel lay).

In equal laid strands the steel area increases compared to cross lay strands. Other advantages of  parallel laid strands are the improved fatigue and wear resistance resulting from the same wire lay length and strand angle.
