We used fiberglass unistrut on this years robot for the elevator lift and arm. Great material. Saved us a ton of weight and stong enough in testing to hold at least 4-5 tetras at 5-6 feet or at least one mentor trying to break it. Look at 1108 Teaser #1 and #2 to see our fiberglass or I'm sure you can find a competition picture somewhere.
