Your local steel yard will have it in lengths without holes in it for cheap. 2" x 2" square tubing.. I'm not sure what the thickness should be, but I'd guess since we are talking about the weight of the commander dropping down on it, 1/4" I don't think there is anything thicker without going to a solid piece of steel. Solid is quite a bit more expensive though. http://www.metalsdepot.com will give you some prices, they are pretty high compared to what I could get locally though even if I didn't have to pay shipping.
1/8 square stock would be good 3/16 would be better. So 10 gauge would be about 1/8 I think, wheres Doc? Anyway those are the two sizes I see in skids the most which in square stock would be even stronger so I don't think you need to go any thicker.
