4. The Core IWRC Strand Fiber

5. How to describe any wire rope A typical wire rope may be designated 6X25 FW PRF RLL XIP IWRC. This translates to: A 6 strand (6X25) of filler wire construction (FW). The grade of wire used is Extra Improved Plow Steel (XIP). The strands are preformed (PRF) in helical pattern before being laid Right lang (RLL) around an Independent Wire Rope Core (IWRC).
