Nov 01, 2019 · G90 .90 oz coating per square foot. Thicker coatings generally last longer, because they take longer to corrode. However, that means they also have decreased workability. Galvannealed Steel. Galvannealed steel goes through an extra processing step. Once the raw steel is coated in zinc, it is then heated to a higher temperature (over 1000° F).1. Metallic-Coated Products and Specifications prime g90 mill surface zinc coated steel sheetprecisely. 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. For a coating equally applied to both sides of the sheet, this means there is about 0.0008 inches (21 microns) of zinc on each surface. To accurately determine the thickness of the coating, the
