    Abstract

    Results of 3 to 7-year exposure periods of galvanized steel specimens in Ontario and Quebec highway environments are reported. Continuous hot-dip, batch hot-dip, and electrogalvanized materials were used. Results indicated that a coating life of five years per mil of coating can be expected in urban environments, and 10 to 20 percent longer protection in rural environments. The method of zinc application appeared to have no significant influence.
