The answer is simply that it is difficult to directly measure the thickness accurately. In addition of providing the desired color for the final product, painting also further improves the corrosion protection of the final product. As the industry standard, ASTM A123 Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products, provides requirements for hot-dip galvanized coatings on various steel products. Example: G90 (0.90 oz/ft 2) = Z275 (275 g/m) If what we are interested in is the coating thickness, why do ASTM standards not use thickness measurements? The skin-passed surface quality B is recommended when high surface quality for the painted surface is required. They may be bent flat upon themselves (within accepted bend radii) in any direction at room temperature without cracking.

Similarly the increase in coating thickness increases slightly the required welding current. One of the advantages which pre-galvanized steel has over hot dip galvanized steel is that it has a better appearance. The metal coating has an advantageous characteristic of serving as lubricant, which works greatly with low and moderate surface pressures taking place in forming. When any fusion welding methods are used, the heat input must be as minimal as possible in order to limit the heated zone in the metal coated sheet. G90 Galvanized Coating Z275 Coating Sheet Coil. The answer is simply that it is difficult todirectly measure the thickness accurately. ISQ specification only. 0000071450 00000 n INTRODUCTION: GALVANISED STEEL IRON COIL AND SHEET Galvanized sheet or coil is a process by which zinc, a non-corrosive metal, is coated over corrosive metals, such as iron and steel.
