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.
