Galvanized Wire Rope with 6x19 Construction and Fiber Core

A galvanized wire rope with a 6x19 construction and fiber core nominal diameter 6 mm features a central core made of natural or synthetic fibers, surrounded by six main strands. Each of these six strands is itself composed of 19 twisted steel wires. The fiber core design offers key advantages: it acts as an internal lubricant reservoir, absorbing and retaining lubricant to reduce maintenance frequency and extend service life. Secondly, this structure provides high flexibility, making the rope ideal for applications involving small sheaves or complex routing. The galvanized coating applies a sacrificial layer of zinc to the steel, offering robust protection against corrosion and rust, which significantly enhances durability in humid or outdoor environments.

The tensile strength of this wire rope is directly dependent on the grade of steel used. For instance, 6 mm diameter ropes in a standard tensile grade e.g., 1770 MPa can have a nominal minimum breaking force of approximately 21 kilonewtons equivalent to about 2140 kilograms. This level of strength, combined with high abrasion resistance due to the balanced number of fine wires, makes the product suitable for a wide range of medium-duty industrial applications. Its primary uses include small to medium cranes, construction hoi
