Standard Specification for Zinc and Epoxy Dual-Coated Steel Reinforcing Bars
ASTM A1055/A1055M-25
Organization:
ASTM - ASTM International
Year: 2025
Abstract: This specification covers deformed and plain steel reinforcing bars with a dual coating of zinc alloy and an epoxy coating. The zinc alloy layer shall be applied by the thermal spray coating method followed by an epoxy coating, which shall be applied by the electrostatic spray method. The zinc coating shall conform to the required chemical composition for aluminum, cadmium, copper, iron, lead, tin, antimony, silver, bismuth, arsenic, nickel, magnesium, titanium, and zinc. The coated steel reinforcing bars shall conform to bend test requirements and to physical properties such as coating thickness, coating continuity, epoxy coating flexibility, and coating adhesion.

| scope | 1.1 This 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. 1.2 The 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). Note 1: The coating applicator is identified throughout this specification as the manufacturer. 1.3 Requirements for the zinc coating are contained in Table 1. 1.4 Requirements for epoxy powder coatings are contained in Annex A1. 1.5 Guidelines for construction practices at the job-site are presented in Appendix X1. 1.6 The 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. 1.7 This specification is applicable for orders in either inch-pound units [as Specification A1055] or SI units [as Specification A1055M]. 1.8 The 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. 1.9 This 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. 1.10 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. | |
