Zinc-Coated (Galvanized) Steel Bars for Concrete Reinforcement

ASTM A767

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.

WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM A767 for Zinc-Coated (Galvanized) Steel Bars for Concrete Reinforcement. Contact us to learn more.
