Left lay means just the opposite: strands pass from right to left. Regular lay and lang lay describe the way wires are placed within each Filler Wire strand. Regular lay means that wires in the strands are laid opposite in Small wires fill spaces between large wires to produce direction to the lay of the strands. Lang lay means that wires are laid in crush resistance and a good balance of strength, the same direction as the lay of the strands. flexibility and resistance to abrasion.
