Predicting the service life of galvanized steel

May 29, 2003· Zinc, which has been used to hot-dip-galvanize steel for 250 years, provides 50 to 75 years of corrosion protection in many environments. Empirical data collected about hot-dip galvanized (HDG) steel field performance from 1940 to 1980—in environments ranging from industrial to marine to suburban—indicates that zinc can prevent base steel corrosion more than other surface treatments.
