Is this going to hold

[sphelps]

Without going into too much detail I ran half the frame with half the weight using A36 steel in the size you're planning and you barely get a safety factor of 2, typically for this application I like to see 5 or more. 2" with a .25 wall will give you close to 5 following the same stand design/layout.

If you are using 2x2x.250w HSS the grade would either be a G40-21 350W or an A500 GR C . This would increase your safety factor and possibly enable him use a lighter wall thickness.

A36 HSS? Dude, where you gettin' steel from?

I ran some similarly technical tests and determined this would not work:

its true brett it didnt there was a design flaw so they had to revamp the whole thing and after 3yrs of structural engineering they managed to come up with this :

A36 is the most common and readily available steel grade used in structural fabrication.

If it is possible go with 2 mid supports splitting the tank length into 3rds.

In the states for the most part. A36 yield and tensile strengths (36K) are no where near what Canada uses or at least Saskatchewan. Tubing and beam are most often called with a 50K yield and bars with 44K.

Yes there is stronger steel out there but A36 is pretty common even here in Canada and you'll also have a hard time finding 1-1/4 in anything cold rolled, likely it will be hot rolled and at best A-36. Plus $20 says they have no idea what steel it is so for me to assume it's the strongest available would be pretty foolish. Anything you get from a local hardware store isn't anything special. Like I said before, without getting into too much detail that's what I came up with, take it for what it's worth to you.
