Description of ASTM-A810 2009ASTM A810 - 01(2009)e1Standard Specification for Zinc-Coated (Galvanized) Steel Pipe Winding MeshActive Standard ASTM A810 | Developed by Subcommittee: A05.12 Book of Standards Volume: 01.06
Translated Standard: Russian ASTM A810Abstract This specification deals with various designs of zinc-coated steel pipe winding mesh to be used as reinforcement for the concrete applied in the manufacture of negative buoyancy pipe needed for laying pipe in marshes or in water. This mesh can also be used as reinforcement for concrete applied to pipe as a bendable or nonbendable mechanical protective coating when laying pipe in a harsh environment. The types of fabric to be used are classified as TW, WW, WW-C, WW-N, and WW-S. The steel from which the wire is produced shall be made by any commercially accepted steelmaking process and the zinc coating shall either be of a Class 1 or a regular coating. Hexagonal woven meshes shall be manufactured by twisting wires to form a series of openings that are hexagonal in shape while welded meshes shall be obtained by welding a series of parallel longitudinal wires to transverse wires to form rectangular openings. Stripping and tensile tests shall be performed to determine the coating weight and tensile compliance of the specimen. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 1. Scope 1.1 This specification covers various designs of welded wire mesh or twisted (woven) hexagonal wire mesh, zinc coated before fabrication, to be used as reinforcement for the concrete applied in the manufacture of negative buoyancy pipe needed for laying pipe in marshes or in water. The mesh is also used as reinforcement for concrete applied to pipe as a bendable or nonbendable mechanical protective coating when laying pipe in a harsh environment. 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 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
