Metals, such as steel, contain Iron and therefore need to be protected from corrosion caused by exposure to air and water. What category of metals is this?
Ferrous Metals
Non-Ferrous metals
Metals which do not contain Iron, are more resistant to corrosion and require less maintenance. Which category of metals is this?
Ferrous metals
non-ferrous metals
Which category of metals require protection using a variety of finishes, including special oil based paints, electroplating processes such as galvanising, and plastic dip coating.
