also add stiffners on all the metal sides....316ss angle.... maybe 2x2x.25 one at the top and one in the middle one each of three sides and along the front top..........i guess i would also frame the opening in the same ss angle...any bowing at the front will cause leaks.....my 2 cents

EXPANSTION FROM THE HEAT OF THE WATER AND LIGHT'S ALSO SCRATCHING FROM SUBSTRATE MITE CAUSE RUST ( SS RUST'S IF SCRATCHED ) SOME ONE HAD A SS TYPE TANK DESIGN ON HERE A FEW MONTH'S AGO ASWELL SOUND'S COOL THOUGH..

BUT DO YOU MAN IF YOU WANNA BUILD IT , YOUR DESIGN LOOK'S STRONG , WEILD'S ARE KEY. A MASTER WEILDER IS NEED FOR THIS JOB.. .. :D

GOOD LUCK..

Oh, I wanted to add that the square tube design would be stronger mechanically. See if a different welder can solve the bowing problem. I am not a very experienced welder, but a good one will know the solution to the problem. It is in the clamping and starting from the center, working outward evenly (and having a second person keeping a torch on the whole thing). What causes the bowing is thermal expansion and cooling. It is enough to drive any novice welder insane. You have to understand it to control it and it is clear that your journeyman does not understand it. Get someone that does. You should not have to pay for his practice.

Honestly, spend the money on a civil engineer. Take your plans to one with ProE or an equivalent. They will enter it while you are sitting there and it will give you the required dimensions you are looking for. The program will also tell you stresses, strains, deformations, and possibly the integral value of the water pressure. The cost will range from $150 if the guy likes you to $400 if it is a firm with better things to do.
Best advice in the thread. Cost of the consultant is chump change compared to the material and possible design failure costs. He can probably give good advice on the stand requirements at the same time.

Do it right but get it built! :drool: I want to see some pics :popcorn:

thanks to everybody who replied. I contacted a consulting company that specializes in structural design. they would charge me $ 135.00 per hour. I submitted my drawing to them yesterday, I should get their recommendation on Monday.

kidding right?
Lets just keep in mind that inexperienced people read these comments and may take a cavalier attitude towards a very real concern if those who are experienced and respected for giving good advice are quick to do so. :irked:


Darwin usually wins...:D

You must be new to the program...SS framed tanks 40-50 yrs old and before that cast iron. (I still use my 5 SS framed tanks)

Honestly now... there's just as much chance of shock with the water as the SS. You have your tanks equipment plugged into a GFI don't you? I do, and I promote/require it with my customers. And I don't want to hear the about conduction thru fresh water arguement etc.

It's not a cavalier attitude...IT WAS A JOKE! :ROFL:

I still say Canadians have too much time on their hands...;)

But I do thank you for the compliment tho...
