Abstract

This specification covers steel reinforcing bars with protective zinc coatings applied by dipping the properly prepared reinforcing bars into a molten bath of zinc. Galvanization shall be used to prepare reinforcing bars. The galvanizer shall be permitted to subject the newly coated steel reinforcing bars to air or steam wiping to remove excess zinc from the bars. The mass of zinc coating shall conform to specified requirements. The mass of the coating shall be determined by magnetic thickness gage measurements. Stripping method, weighing before and after galvanizing, and microscopy method shall be used to referee the results obtained by magnetic thickness measurements. A retest shall be provided if the average zinc coating mass fails to meet the requirements. The galvanized coating shall be chromate treated.

Scope

1.1 This specification covers steel reinforcing bars with protective zinc coatings applied by dipping the properly prepared reinforcing bars into a molten bath of zinc.

1.2 This specification is applicable for orders in either inch-pound units (as Specification A 767) or SI units (as Specification A 767M).

1.3 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. Combining values from the two systems may result in nonconformance with this specification.
