(Specification)Standard Specification for Zinc-Coated Steel Chain-Link Fence Fabric
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 standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 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.
