I've been assembling various and sundry pieces and parts for my single tier brewstand. I'd buy it all at once but Im counting on individual purchases passing below the radar of the household ways & means committee.
That being said, one of the bigger purchases is the metal for the stand itself. Im going with 304 square stainless tubing. Many of the stands I've seen use 10 guage 2"x2" (approx 1/8"). My local metal shop charges about $15 / foot for this stuff. Im thinking it might be overkill.
My question is simple: what is the appropriate size tubing for this job? My weight assumptions are:
wort/water: 9 lbs / gallon
kegs : 30 lbs
fitting: 40 lbs
If the kegs are filled to capactity we're looking at 420 lbs so let's add another 35 for grain the grand total is 578 lbs. Add 10% for safe measure and we right around 620 lbs. My highly technical drawing is below:
Couple of good reads:

which cover tubing strengths. I cant see where 1.25" sq tubing w/ 11 guage wall thickness wouldnt be more than enough. Thoughts?
