WebWhat is the thickness of a galvanized coating? When it comes to the specification of hot dip galvanizing, most contractors know that to be standards compliant, 7mm steel requires an average coating thickness … WebIf what we are interested in is the coating thickness, why do ASTM standards not use thickness measurements? The answer is simply that it is difficult to directly measure the thickness accurately and precisely. For example, a G90 coating contributes about 1.6 mils (0.0016 inches, or about 42 microns) to the total thickness of the coated sheet.
