ASTM WK77330

Revision of A385/A385M-20 Standard Practice for Providing High-Quality Zinc Coatings (Hot-Dip)


Address industry concerns regarding thick HDG coatings and available methods to prevent flaking during transport and field handling. Remove recommendations for over-pickling in sulfuric as a method to remedy low coating thickness for Al-killed steels. Over-pickling cannot be measured and can result in poor coating quality. Additional language added to clarify the difference in outcomes achieved when blast cleaning steels before galvanizing based on the steel chemistry.
