Engineers, architects, DOTs and other specifiers use hot-dip galvanizing to provide corrosion protection to steel and iron in many industries, including transportation and highway, parking garages, bridges, structural, agricultural, petrochemical, and original equipment manufacturing. To ensure continued corrosion protection and structural integrity in these industries, it is necessary to properly inspect the galvanizing. This paper provides an introduction to commonly used standards and inspection criteria for ensuring high quality galvanized coatings.
