Yeah. Don't use steel corrugated metal.

Here in Australia we use a lot of corrugated metal, but it's either "zincalume" or "Colorbond steel." That latter is corrugated steel coated with zinc and then with a an anti-corrosion primer and a specialized exterior paint. It's used in siding, roofing and fencing. We had it on a house near the ocean and in 10 years it hadn't rusted at all. I assume there'd be something equivalent in the US.

I can't imagine ordinary corrugated metal lasting for long, though.
