Standard Specification for Zinc-Coated Steel Structural Wire Rope

This specification covers zinc-coated steel structural wire rope, prestretched or nonprestretched for use where a high-strength, relatively flexible prefabricated zinc-coated multiple-wire tension member is desired as a component part of a structure. The wire rope is furnished with Class A weight zinc-coated wires throughout. It can be furnished with Class B weight or Class C weight zinc-coated outer wires or Class B weight or Class C weight zinc-coated wires throughout where additional corrosion protection is required. The steel shall conform to the following tensile requirements: tensile strength; bend-free or kink-free test specimens; stress at extension under load; elongation; ductility; weight of zinc coating; adherence of coating; and finish. The weight of the zinc coating shall be determined by a stripping test made on the individual wires prior to fabrication of strand. When specified, the wire rope shall be prestretched. The prestretched rope shall meet the required minimum modulus of elasticity.
