I'd like to use galvanized metal conduit as deck balusters with pressure-treated lumber. Will the bare metal resist rust? If not, is there an inexpensive way to improve its rust resistance?

Best Answer
Rigid conduit (which is pretty much the same thing as galvanized steel pipe) is galvanized with a considerably thicker layer than EMT - it's also stronger (emt is a bit flimsy for a railing) and more expensive (such is life.) Since you didn't specify what type of galvanized metal conduit you were considering using, what happens will vary with the type you choose.
