I agree with Ron. Just because it is outside under a canopy would not mean it has to be galvanized. I think a lot has to be where the building is located. I would be perfectly happy with a coat of paint on the piping in an area where occasionally the pipe might be exposed to the elements.

I wouldn't have a bit of trouble worrying about black piper exposed to weather in Arizona or Saudi Arabia. Might get a surface rusting but that's protective. I might, on the other hand, be horrified of the thought of using anything but that stuff that has the zinc impregnated into the outer layers of the steel rather than as just a coating (don't want to name it and be accused of advertising a product) on a North Sea offshore oil platform, even for inside stuff. All is situational.
