I did the metal fume fever thing once (didn't know it was called that...)
Trust me when I say that you do not want to go through that.
If you end up deciding to use the galvanized stuff, I'd sand/wire brush
the heck out of it or (better) sand blast it. Either way, make sure you
have some ventilation when you weld it, and make sure your head isn't
directly over where you're welding.
All that said, I think Lowe's & HD carry sheet metal in various guages.
There's also www.metalexpress.net, and probably a ton of other options.
