(Specification)Standard Specification for Vinyl-Coated Steel Wire and Welded Wire Reinforcement
Standard Specification for Vinyl-Coated Steel Wire and Welded Wire Reinforcement
ABSTRACT
This specification covers steel wire and steel welded wire fabrics which are either plain or deformed, and coated with protective polyvinyl chloride (PVC). Class A material is intended for use as concrete reinforcement and Class B for reinforcement in earth. Coating materials shall adhere to chemical resistance requirements. The surface of the material to be coated shall be cleaned by abrasive blast cleaning to near-white metal. The coating shall be applied to the cleaned surface as soon as possible after cleaning and before oxidation, as discernible to the unaided eye, occurs. The coating shall conform to set coating thickness and holidays. Adhesion of coating shall be evaluated by bending test. Guidelines for inspection, rejection and certification are also given.
SCOPE
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.
