Angle Iron vs. Square Tube?

Just do some simple beam equations for the weight concentrated in the middle of 2 fixed joints and see how close you are to yield strength.

look at page 5 here and use low carbon alloy cold rolled steel for your values.

I would guess that is the highest loading area, you can always put more vertical stiffeners on the sides.

Cold rolled ups the price quite a bit...

Just stating a general value to use for a quick analysis look...since that number is fairly easy to find, but yes actually buying CRS you are correct.

Gotcha
Using the calculator is excellent advice. We use one when we get requests for over-sized stands.

I ended up going with 2x2 tube. It is a pain to drill a straight hole through if you dont have a drill press. But it is easier to weld together and get nice corners with. My only regret is I used 11 gauge steel which is way overkill. My rig weighs a ton.

But it can probably get hit by a truck and be ok.

Just finished mine at the end of summer. 2x2 square tubing. Got.it for $40 from a friend. Learned how to weld by building it. Spent more on flap discs and grinding discs than I did on the steel but it is an awesome rig and it works splendidly
