Is it better to use galvanized or black iron pipe when piping LP gas in a outside application?
Galvanized for water, black for gas. You can always paint the black if you are worried about it rusting.
That would depend on local codes as many do not allow the use of galvanized and other codes state "where moisture is present galvanizing coating shall be applied.
