Webweight (thickness). For instance, a G60 coating has twice the thickness of a G30 coating, and the life of the product (defined, perhaps, as the time to 5% rust) in a given environment is approximately twice as long. Similarly, a G90 coating is approximately 50% thicker than a G60 coating, and thus would be expected to perform 50% better (in ... WebZinc coating thickness on galvanized sheet has a linear relationship to service life and for building interior service, coating grade G-60, which has two-thirds the life expectancy of G-90, is consistent with anticipated building service life of 30 years. Base metal thickness is reduced as zinc coating is increased. megapixel was ist gut
