Title should say "angle iron"

I am going to have a stand built for a new tank this week.. tank size is 6x3x2 270gal acrylic. built with 2x2x1/4" angle and 2"x3/8" flat bar for support gussets

I am curious to know a few things..

1) which design is the better one
2) would this be strong enough to hold this size tank(both designs, or just one)
3) any other design that is better, please edit mine, and add here.

Thanks.

Are you welding or bolting? Thats a lot of pressure on the angled flat stock. You're looking at around 2100 lbs. worth of water (plus the acrylic, plus filtration plus plus plus). I'd bet you'll be close to 3000 lbs sitting on that stand, and with your current design all of that weight will be sitting on the bolts, trying to shear them like scissors.

It might hold, I don't have that much experience with metal fabrication to to tell you 100%, but if you build that buy the strongest bolts you can find.
 
Pic #2 with the base. The legs are not a good idea in pic #1. Its too much weight. The base will distribute weight on the floor , not just in 4 3x3 spots. Also I'd put some small gussets on the side profile so it will stiffen up the front to back movement. 1/4" angle is heavy duty you should be ok. This is all being welded right?
 
No sump? No middle shelf? A center leg (front and back) would offer better structural integrity than gussets.

i would weld, but people under estimate bolts. a 7/16 bolt has a 7800-17800 psi shear rating.

7800 - 17800... Thats a pretty big range.

How far does that come down if the table wobbles and their is grinding action? How long can they withstand that pressure?

I'm just saying that there are ways to build that the bolts aren't what is holding the weight. Build the stand so that the weight is distributed downward to the floor, rather than outward.
 
welds are stronger then mild steel. In the neighborhood of 50-80k psi. The metal will tear first so if its welded it will be fine. But you need to make sure you have no sheer points. You would need either a center leg or a spreader bar to keep the legs from moving out under load and bending.

Also, isn't full bottom support recommended for acrylic tanks? If you plan on putting a top deck on the stand your fine then. But I didn't see it mentioned so thought I would point that out. I could be wrong though.
 
I also plan on putting a 3/4" sheet of plywood over the top...
fallin49er, i like that stand. I just finished making a new design when you posted... pretty simular.
