Regular galvanized is ordered with the designation of “G” coatings. Alloyed coatings are ordered with the designation of “A” coatings. Normal designations for the regular zinc galvanized product are G90 and Three test pieces (edge-center-edge), taken in accordance with ASTM standards, are stripped of coating by an approved method, and the coating is determined by the average difference in weight before and after stripping.
