ASTM A123 and G90 Specifications, Authored by Batch galvanizing coating specifications are given in weight per surface area. The designation G90 is simply a coating thickness of 0.9 oz/ft2 as specified in A653 and is equivalent to 0.45 oz/ft2 or about 0.76 mils per side (it is important to state per side because the oz/ft2 method takes into consideration the coating thickness on both sides of the steel, such as in the case of sheet steel). Hot-dip galvanizing is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 860 °F (460 °C). A bend test shall be done to the coated sheets. Sheet steel is always galvanized coil to coil. Also for use in sheet metal work directly exposed to the elements. 108. MPa. If you are simply trying to specify a galvanized coating thickness that is 0.9 oz/ft2 or greater, that should not be a problem using the batch galvanizing process (where the steel is fabricated and then dipped into a kettle of molten zinc), but if the steel is very thin, warpage/distortion is a possibility.
