On its Australian introduction in the 1980s, 410Y Grade rebar was subjected to extensive testing to validate its suitability for hot dip galvanizing without requiring any special post-treatment. The satisfactory results from this test program resulted in the galvanized rebar option being incorporated into the standards, codes and practice notes that have been used as reference documents for the reinforced concrete industry since the mid-1980’s.
