This paper outlines the advantage of using galvanized steel to protect critical structural members from corrosion. For example, the mean 2 X 106 cycle fatigue strength for 0.070 and 0.085 in thick galvanized steel was approximately 26,000 psi. It was unaffected by exposure to 96 h of salt spray before testing. Comparable fatigue strength for 0.095 in thick hot rolled steel of nearly equivalent chemistry was about 28,000 psi. Exposed to 96 h of salt spray, it dropped to about 25,400 psi.
