You can find 3/4" x30" aluminum square tubing at Menards. It is black powder coated and it meant to be a spindle for stair rails. They also have round tubes. Both are $2 before taxes or mail in rebate. The square tubes seem to be straight. I just figured I would share the info in case someone could make use of it.
