Aluminum, Aluminized Steel And Galvanized Steel In Severe Coastal Environments Available to Purchase

Aluminum, aluminized steel and galvanized steel pole line hardware were exposed in a severe marine environment near Kahuku Point, Oahu, Hawaii for three years. Variables included aluminizing process and type of base steel. Evaluation of samples after three years’ exposure indicates: (1) the superior performance of all-aluminum hardware, (2) the improved corrosion resistance of aluminized steel to that of galvanized steel, and (3) the relationship between the thickness of aluminum coatings and the service life of aluminized steel hardware. Thicker aluminum coatings result in longer life. 2.2.2, 4.2.5, 6.4.2, 5.3.4
