Galvanized Cable
Metal cable put through the galvanizing process has been hot dipped in zinc, which forms a rust and corrosion resistant outer coating. This increases the durability, temperature and ware resistance of the cable, making it more useful in outdoor applications or conditions where extreme temperatures and precipitation may be a concern. The individual strands, wire or rope may go through the galvanizing process. The construction, sports equipment, rock climbing, marine and aerospace industries all use metal cable that has been galvanized to manufacture products and aid in processes. Galvanized cables may be used in bicycle manufacturing, flight control avionics, scaffolding, rigging, climbing equipment, sailing and boat rigging, gym equipment and bridge construction.
Galvanization is a post-forming process that is accomplished two different ways. The most common, hot dipping, involves submerging the metal cable into molten zinc which has been heated to around 860 degrees F. The zinc chemically reacts with the iron or steel, and forms a brittle alloy with a wide range temperature resistance. Another galvanizing process is called electrolytic galvanizing, a cold forming process in which the metal cable is brushed or painted with an organic solvent containing zinc particles. As the solvent evaporates, the zinc chemically reacts with the metal to form the same rust and corrosion resistant coating that provides strength and the ability to function in a wide range of atmospheres and conditions.
