scope

1.1 This specification covers deformed and plain steel reinforcing bars with a dual coating of zinc alloy and an epoxy coating. The zinc alloy layer is applied by the thermal spray coating method (metallizing) followed by an epoxy coating applied by the electrostatic spray method.

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

1.2 Requirements of the zinc coating are contained in Table 1.

1.3 Requirements for fusion-bonded powder coatings are contained in Annex A1.

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

1.5 This specification is applicable for orders in either SI units or inch pounds units.

1.6 The values stated in either SI or inch-pound units are to be regarded as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not 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 nonconformance with this specification.

1.7 This standard 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 standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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.
