Hot dip galvanized vs. standard zinc plated in 95% humidity 60 degree constant temp. 

+

I am providing steel conduit and hardware to be installed in a freight tunnel system in Chicago. Several of our components are simply zinc plated. I need to provide some information on the lifecycle of Zinc plating in that tunnel environment, which is reported to be 95% humidity at 60 degrees farenheit constant. Is there a corrosion resistance chart available that I Could use for reference.
