galvanizing (sh)




Protection of iron or steel against exposure to the atmosphere and consequent rusting by application of a zinc coating.

Properly applied, galvanizing may protect from atmospheric corrosion for 15-30 years or more. If the coating is damaged, the iron or steel continues to be protected by sacrificial corrosion, a phenomenon in which atmospheric oxidation spares the iron and affects the zinc (as long as it lasts).
