The corrosion resistance of zinc coatings is determined primarily by the thickness of the coating but varies with the severity of environmental conditions. Each environment affects hot-dip galvanizing differently based on a unique set of corrosion variables. The predictability of the lifetime of a coating is important for planning and budgeting for required maintenance.
Whether exposed to the atmosphere, subjected to blazing UV rays, snow, and/or other elements, submerged in water, embedded in soil or concrete, or various other environments, hot-dip galvanized steel can withstand the different corrosive elements and fulfill the intended design life.
