Abstract
Requirements for improved durability in domestic consumer goods have invariably led to the application of more corrosion resistant materials. The basic material used by many industries, including automotive, ventilation and heating, construction, appliances, and furniture is sheet steel. Zinc-coated or galvanized sheet steels are the obvious corrosion resistant material choice for these industries. Steel sheet can be coated with zinc (galvanized) through either electrolytic or hot-dip processes, with coating weight between 30 g/m 2 and 400 g/m 2 (approximately 4 à µm to 55 à µm thick) depending on the process condition
