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