Perforated square tubing or "bolt together" framing.
You might also consider 80/20-style T-slot framing.
I'm not associated with McMaster-Carr, but I'm a big fan of theirs. You can find perforated square tubing on their site here and you can find 80/20-compatible T-slot framing here.
Of course, if you're looking for 80/20 framing, you could always go to the 80/20 website.
