Standard Specification for Metallic-Coated Steel Wire for Chain-Link Fence Fabric and Marcelled Tension Wire
The following bibliographic material is provided to assist you with your purchasing decision:
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.
Scope
1.1This 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:
1.1.1Type I—Aluminum-coated (aluminized),
1.1.2 Type II—Zinc-coated (galvanized), and
1.1.3Type 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 A 491
1.3 The marcelled tension wire manufactured from wire in this specification is covered separately in Specifications A 824
1.4 This specification does not cover the wire used for Specification A 392
The values stated in inch-pound units are to be regarded as the standard. The values given in brackets are provided for information only.
