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
- Fiber Core: Polypropylene is standard, but either natural sisal (or hemp) fiber or other man-made fibers are available on special request.
- 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.
- Strand Core: A strand made of wires. Typically, strand cores are used in utility cables only.
