Standard Specification for Metallic-Coated Steel Marcelled Tension Wire for Use With Chain Link Fence

ABSTRACT
This specification covers the basic requirements for 0.177 in. (4.50 mm) diameter metallic-coated carbon steel marcelled tension wires for use with chain-link fences. Three types of coatings are covered here, namely: Type I, aluminum-coated (aluminized); Type II, zinc-coated (galvanized); and Type III, zinc-5 % aluminum-mischmetal (Zn-5Al-MM) alloy-coated. When tested, the wires shall adhere specified requirements for breaking strength, size, weight of coating, and adherence of coating. The steel rod from which the wire is drawn shall be made by the open-hearth, electric-furnace, or basic-oxygen process, and the corresponding wire shall be cold-drawn, metallic-coated at finished sizes, then marcelled as appropriate.
SCOPE
1.1 This specification covers 0.177 in. (4.50 mm) diameter metallic-coated carbon steel marcelled tension wire for use with chain-link fence. The 0.177 in. (4.50 mm) diameter metallic-coated wire shall be produced in accordance with Specification A817. 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 (Zn5Al-MM) alloy-coated.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 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.
