How thick is a galvanizing coating?

The thickness of a galvanized coating is mostly determined by the thickness of the steel section being galvanized.  For example the British standard for hot dip galvanizing, BS EN ISO 1461 (2009), states that steel thicker than 6mm should have a minimum mean galvanized coating thickness of 85 microns and a steel section of 3mm – 6mm should have a minimum mean galvanized coating thickness of 70 microns.
