ASTM A 1055/A1055M : 2025

1.1This specification covers deformed and plain steel reinforcing bars with a dual coating of zinc-alloy followed by an epoxy coating applied by the electrostatic spray method.

1.2The zinc-alloy coating is produced as one of two types: zinc-alloy applied by the thermal spray method (Type I) or zinc-alloy applied in accordance with Specification A1094/A1094M (Type II).

1.3Requirements for the zinc coating are contained in Table 1.

1.4Requirements for epoxy powder coatings are contained in Annex A1.

1.5Guidelines for construction practices at the job-site are presented in Appendix X1.

1.6The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.

1.7This specification is applicable for orders in either inch-pound units [as Specification A1055] or SI units [as Specification A1055M].

1.8The values stated in either inch-pound units or SI units are to be regarded 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 must be used independently of the other, except as specifically noted in Table 2. Combining values from the two systems may result in non-conformance with this specification.

1.9This specification 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 specification to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.10This 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.
