This specification covers metallic-coated carbon steel wire for the manufacture of chain-link fence fabric and marcelled tension wire. Three coating types, namely: Type I (aluminized), Type II (galvanized), and Type III (zinc-aluminum-mischmetal alloy-coated), and five coating classes, namely: Class 3, Class 4, Class 5, Class 60, and Class 100, are covered. This specification does not cover the wire for chain-link fence when the coating is to be applied after the weaving process. The steel rod from which the wire is to be drawn shall be manufactured by the open-hearth, electric-furnace, or basic-oxygen process. The wire shall be cold-drawn, then metallic-coated at finished size to produce the specified mechanical properties such as breaking strength. Type I and Type III coatings shall be produced by a hot-dip process and Type II coating by either a hot-dip or an electrolytic process. The ingot or pig aluminum to be used for Type I coating shall conform to the impurity limits specified for copper and iron. Requirements for coated wire diameter, coating weight, coating adherence, and methods of chemical analysis and breaking strength test are detailed.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers metallic-coated carbon steel wire used in the manufacture of chain-link fence fabric and marcelled tension wire. Three types of coatings are covered:
1.1.1 Type I—Aluminum-coated (aluminized),
1.1.2 Type II—Zinc-coated (galvanized), and
1.1.3 Type III—Zinc-5 % Aluminum-Mischmetal (Zn-5Al-MM) alloy-coated.
1.2 The chain-link fabric woven from wire in this specification is covered separately by Specifications for Type I, for Type II, and for Type III.
1.3 The marcelled tension wire manufactured from wire in this specification is covered separately in Specifications and .
1.4 This specification does not cover the wire used for Specification when the chain-link fence producer applies the coating after the weaving process.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
