Standard Specification for Aluminum-Coated Steel Wire Strand
This specification covers five grades of aluminum-coated, steel wire strand composed of a number of round, steel wires, with aluminum coatings, for use as guys, messengers, span wires, and for similar purposed. The five grades are as follows: (1) utilities; (2) common; (3) Siemens-Martin; (4) high-strength; and (5)extra high-strength. The base metal shall be steel made by any commercially steel making process, The ingot or pig aluminum used for coating shall conform to the required impurity limits of copper and iron. All wires shall be stranded with uniform tension. Physical tests shall be performed wherein the steel wire strands shall conform to the required values of breaking strength. The steel specimens shall also conform to the required values of elongation, diameter and weight of coating.
1.1 This specification covers five grades of aluminum-coated, steel wire strand, composed of a number of round, steel wires, with aluminum coatings, for use as guys, messengers, span wires, and for similar purposes.
1.2 The five grades covered are as follows:
1.2.1 Utilities,
1.2.2 Common,
1.2.3 Siemens-Martin,
1.2.4 High-Strength, and
1.2.5 Extra High-Strength.
1.3 Minimum breaking strengths of strand for each grade are specified in Table 1.
