Talk to your local cold-formed steel manufacturer - there are many around, but they don't generally get a lot of press. CFS is lighter, cheaper, and thinner than tube steel but just as strong when assembled correctly.....and significantly cheaper. Just be sure to pick up a can of zinc spray for your weld seams (or you can actually assemble with self-tapping screws if you have a pneumatic or power driver). I used to design buildings out of CFS and it's hands-down the most cost-effective form of structural-capable steel available. If you stop by job sites where it's being installed via stick-framing (vs. prebuilt panels), there is a good chance that they have scrap pieces in their trash pile that would be big enough for a brew stand. (With this stuff, it's common to have 4-foot-long lengths tossed out - or even bigger pieces that might have been bent or dented!)
