Case Study: Hot Dip Galvanizing and Life Cycle Cost American Galvanizing Association (AGA) Golden Gate Bridge Brooklyn Bridge Opened in 1937 24,000 tons of the two main suspension cables and accessories were hot dip galvanized; they were made up from 80,000 miles of wire Remaining 84,000 tons of steel for the towers and suspended structure was painted “International Orange” 10,000 gallons of paint consumed each year for normal touch up Spend to date on painting and repainting, including full time painters and iron workers - $345M and growing Estimated cost if the entire bridge had been galvanized - $45M Opened in 1883 World’s first hot dip galvanized steel wire cable suspension bridge. They were made up of 14,500 miles of wires While the bridge has had major upgrades to accommodate modern traffic requirements the galvanized suspension system and granite towers are still performing well Appropriate Corrosion Technology Saving Taxpayer Dollars 26 Valmont Industries, Inc. | 2016 Investor Day vs.
