edit: what is "extruded" aluminum? does than mean angle?

80-20 has some nice little demos you can see here:

Essentially the idea is that you can rapidly assemble a frame by using t-nuts that fit inside the channels of the extrude aluminum. No welding is needed, and components can be assembled and reassmbled numerous times. No drilling into the material is required either, since the t-nuts provided threaded holes to use.

And yes aluminum is more expensive than steel, but steel is very cheap. If you're looking to buy box aluminum, you can get 8 feet of 1" x 1" x 1/8" for about $15. I'll say you can get a frame out of roughly 20 or 30 feet.
