Some of the black pipe these days comes with a coating on it, I believe for corrosion resistance. I also believe that painted grooved fittings are acceptable in this application. Please correct me if I am wrong.
If it is an FM project, all dry system piping is to be galvanized. I would definitely explain the "maintenance" costs later and the frequency of such if he pushes the black pipe - a little higher cost now can save a lot later.

Our thought is to used galvanized but the GC is trying to get us to provide raw black steel instead because he says the cut sheet doesn't say it can't be used outside. Common sense alone says this will rust in no time, does anyone know of anywhere in code or otherwise that (I've looked) that I can show this guy it's not a good idea?
