Zinc coatings for iron and steel provide excellent corrosion resistance in most atmospheres, in hard fresh waters, and in contact with many natural and synthetic substances. Zinc coatings are widely used to protect finished products ranging from structural steelwork for buildings and bridges, to nuts, bolts, strip, sheet, wire and tube. The electrochemical relationship between zinc and steel enables zinc coatings also to protect steel at cut edges and at breaks in the coating by a sacrificial action. (See also Zinc anodes: cathodic protection) .As for zinc oxide, zinc dust is made by vaporising metallic zinc. However the vapour is in this case allowed to condense in the absence of air, when it forms a fine powder.The principal uses of zinc dust are in paints and sherardising . It is also used in alkaline batteries and as a chemical reducing agent.
