There are two main types of lays: REGULAR and LANG. Regular lay ropes are less liable to
     develop kinks in handling, they are more resistant to crushing on drums than lang lay ropes.
     Lang lay ropes are more flexible and offer a better resistance against abrasion.

     The size of a wire rope is the diameter of the circle which will just enclose all of the strands.
     The correct method is to measure over any pair of opposite strands.
