Wire Rope Cores

Rope Cores Form A Foundation For The Strands

The primary function of the rope’s core is to serve as the foundation for the strands – to keep the rope round, and the strands positioned adequately during operation. Your choice of the core will affect the rope’s performance.

Three Types Of Cores Are Commonly Used

  1. Fiber Core:  Polypropylene is standard, but either natural sisal (or hemp) fiber or other man-made fibers are available on special request.
  2. Independent Wire Rope Core: An independent wire rope with strands and a core, called IWRC. Most wire ropes made with steel core use an IWRC.
  3. Strand Core:  A strand made of wires. Typically, strand cores are used in utility cables only.
