The gal steel will still rust eventually Converse ,just takes a lot longer than mild steel.
Ok thanks for that Maxwestern, I was thinking wasn't most of the old corrugated iron sheets made back in the day galvanized? I have an old shed where the roof sheets have mostly rusted but the sides are still strong and solid after probably 50 years or so. I guess the roof does cop more of the elements than the sides though.
