ABSTRACT
This specification covers the basic physical requirements for steel chain-link fence fabric that are aluminum-coated before weaving. Fabrics conforming to this specification shall meet specified requirements for weave form and typical diamond count, size of mesh, size of wire, height of fabric, selvage, weight of aluminum coating, breaking strength, workmanship and finish, and standard length of rolls.
SCOPE
1.1 This specification covers aluminum-coated steel chain-link fence fabric, aluminum-coated before weaving.  
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.
