Standard Specification for Zinc-Coated Steel Chain-Link Fence Fabric

ABSTRACT
This specification covers zinc-coated (galvanized) steel chain-link fence fabric, zinc coated either before or after weaving. The wire shall be woven throughout in the form of approximately uniform square mesh, having parallel sides and horizontal and vertical diagonals of approximately uniform dimensions. The top and bottom of the fabric shall be knuckled or twisted. A typical diamond count for each standard height is given. Chain-link fabric shall conform to the requirements specified for (1) mesh size, (2) wire size, (3) fabric height, (4) selvage, (5) zinc coating weight (Class 1or Class 2), and (6) breaking strength. The standard length of rolls and sampling requirements for testing are specified as well.
SCOPE
1.1 This specification covers zinc-coated steel chain-link fence fabric, zinc coated either before or after weaving.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
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.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 chain-link fence fabric—a fencing material made from steel wire helically wound and interwoven in such a manner as to
provide a continuous mesh without knots or ties except in the form of knuckling or of twisting the ends of the wires to form the
selvage of the fabric. Variations to knuckled or twisted selvages are permissible.
3.1.2 diamond count—the number of diamond openings from one edge of the fabric to the other. The diamond count of a given
fabric shall begin at the first completed diamond at one edge and continue to the unfinished ( ⁄2) or full opening at the other edge.
3.1.3 knuckling—the type of selvage obtained by interlocking adjacent pairs of wire ends and then bending the wire ends back
into a loop. The loop shall be closed or nearly closed to a measurement less than the diameter of the wire.
3.1.4 twisting—the type of selvage obtained by twisting adjacent pairs of wire ends together in a close helix of 1 ⁄2 machine
turns, which is equivalent to 3 full twists, and cutting the wire ends at an angle. The wire ends beyond the twist shall be at least
⁄4 in. (6.4 mm) long. This type of selvage is not used on fabric with a mesh size of less than 2 in. (50.8 mm).

5. Materials
5.1 If zinc-coated before weaving, the wire from which the fabric is woven shall conform to all requirements of Specification
A817 for Type II coating, in the class of coating specified (Class 4 or Class 5).
5.2 If zinc-coated after weaving, the base metal shall be steel of such quality and purity that, when drawn to the size of wire
specified and coated with zinc after fabrication, the finished fencing shall be of uniform quality and have the properties and
characteristics as prescribed in this specification.
5.3 Zinc for Coating—The slab zinc, when used for the coating, shall be any grade of zinc conforming to Specification B6.
6. Weave
6.1 The wire shall be woven throughout in the form of approximately uniform square mesh, having parallel sides and horizontal
and vertical diagonals of approximately uniform dimensions. The top and bottom of the fabric shall be knuckled or twisted as
specified in Section 10.
6.2 A typical diamond count for each standard height is shown in Table 1. Other diamond counts are permissible provided that
they are consistent within a lot. The purchaser has the option to specify the diamond count (see 4.1.6).

of the mesh, and determined as the average of two readings taken at right angles to each other.
