Wires are laid geometrically to form strands, each composed of two or more wires. Breaking these strand configurations into several classifications is the basis for identifying wire rope.
The core is the supporting member of the rope, made of either synthetic or sisai fibers, or steel. A fiber core rope offers flexibility;-a steel center rope yields a higher strength along with the ability to resist crushing Steel cores are required when the environment exceeds 180Â°(F)
NOTE: When fiber core is specified, the core material (synthetic or sisal) could vary. The most popular fiber core is manufactured in polypropylene.
