1.1 This specification covers plain and deformed steel wire and plain and deformed steel welded wire reinforcement with protective vinyl (polyvinyl chloride, or polyvinyl chloride powder compound) coating. A Class A minimum coating thickness is required for wire and welded wire reinforcement intended for use in concrete and masonry. A Class B minimum coating thickness is required for wire and welded wire reinforcement intended for use in mechanically stabilized earth applications.

1.2 Other thermoplastic organic coatings may be used provided they meet the requirements of this specification.

Note 1—The coating applicator is identified throughout this specification as the manufacturer.

1.3 Requirements for coatings are contained in Annex A1.

1.4 Requirements for patching materials are contained in Annex A2.

1.5 The text of this specification contains notes or footnotes, or both, that provide explanatory material. Such notes and footnotes, excluding those in tables or figures, do not contain any mandatory requirements.

1.6 This specification is applicable for orders in either inch-pound units (as Specification A933) or in SI units [as Specification A933M].

1.7 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
