Unfortunately, you are correct since tubular steel is not listed in the additional hardware list. Steel angle up to 2" x 2" x 1/4" is, however you're better off from a weight perspective if you stick with aluminum. If you can find a machine shop near you to weld the aluminum frame, you'll have a solid structure on which to hang your components. Try to get them to donate their time in return for sponsorship of your team. But hurry -- the clock is ticking!
