Below is a list of Galvanized Cable manufacturers from Landisville, Pennsylvania. Galvanized cables are wire ropes that have undergone a metallurgical process known as galvanizing to increase corrosion resistance, durability and temperature resistance. Individual wires, strands or the cable as a whole may be treated with zinc for improved product features and longevity. The process enhances both the internal properties of the underlying steel and creates a protective exterior layer.
