Yes on the galvanized. If you used short pieces, I think they'd be heavy enough.Yes 1 5/8". Those are all galvanized correct? Think they would be heavy enough?
If it's an option, solid is a better choice, like @CharlieK alluded to.I don't know anything about the galvanized fencing stuff, I've never really been around it... but the closest pipe you can fit will be 1", which has a 1.315" OD. Pretty sloppy. If it can be solid, 1-1/2" solid round is really common, and that would make it pretty stout as well.
