Abstract
A corrosion resistant rope in which the individual strands are sealed with a plastic foam impregnant and which exhibits excellent retention of lubrication is made by preimpregnating the outer strands of the rope with plastic foam material prior to closing the strands into a wire rope. The final rope may then be surface lubricated to provide temporary and long term corrosion resistance and lubrication to exposed surface wires.
