7×7 PCG Wire Rope

7×7 PCG Wire Rope

For many applications, the 7×7 PCG design has proven far superior to all other known types of plastic coated wire rope. It has also outlasted bright, galvanized and stainless steel ropes – especially where submersion or abrasion prevents formation of a protective oxide film, which these metals require to resist corrosive elements. Under such conditions, 7×7 PCG plastic-impregnated and coated galvanized wire rope offers important advantages to users.

With ordinary plastic-coated wire rope, the individual metal strands are in direct contact with each other at many points. As a result, the metal-to-metal contact causes internal friction and wear. Even more important, with conventional constructions, there is no interlocking bond. If the outer cover becomes cut or abraded, it is easily peeled off, exposing the bare metal strands to corrosion.

In 7×7 PCG construction, each individual strand is separated from all the others by one or more extra-large “spacer-wires.” This design serves two important functions: (1) It enables the extruded plastic to form a wall of protection around EACH strand. (2) It also assures a tight, interlocking bond between the inner plastic filler and the outer plastic jacket. No peeling or leaking. In 7×7 PCG construction, each individual wire is galvanized for additional corrosion protection.
