ASTM A123 and G90 Specifications American Galvanizers Mar 12, 2013 · G90 is not a galvanizing specification; it is a coating thickness designation in the galvanizing specification ASTM A653. This specification is for hot-dip galvanizing steel sheet using the continuous (high-speed) galvanizing process. ASTM A123, Standard Specification of Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products, refers to products fabricated and then hot-dip galvanized

GalvInfoNote Understanding Coating Weight linear as a function of coating weight (thickness). That is, a G60 coating has twice the hickness of a G30 t coating, and the life of the product (defined, perhaps, as the time to 10% rust) ina givenenvironment is approximately twice as long. Similarly, a G90 coating is approximately 50% thicker than a G60 coating,
a minimum G90 (Z275) or heavier is recommended, and for additional protection in corrosive or polluted environments, prepainted galvanized products should be considered. Galvanize and GalvalumeTM steel should not be combined on the same building elevation because Galvanize will likely exhibit corrosion before Galvalume. As a
Introduction Coating Weight [Mass] Measurement SystemsFor 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 terms of time to 5% rust).
