Good day fish people :)

I want to build a stand for my future 3m x 1m fish tank. I would like the stand to be made out of aluminium.

But, unfortunately, i cannot find any sites that can give me any info on how much weight an aluminium stand can withstand. My tank, I presume, will weigh over 2.5 tons once filled and aquascaped.

I am thinking of using 90mm t-slot aluminium extrudes. Can anybody tell me if this will work or should i just go for wood or steel.

Specs on the aluminium :
T Slot Aluminium

90 x 90mm Heavy Duty T-Slot
• Ideal for heavy-duty applications where added strength is

needed and additional T-slot are needed.

• Centre area can be used as a conduit for air lines, or as

a pressurised air manifold.

• Has eight 10mm T-slots



Moments of Inertia

lx (cm4) 245,00

ly (cm4) 245,00



Section Modulus

Wx (cm4) 54,0

Wy (cm4) 54,0



Profile Mass

Kg/M 7,350



Outer Perimeter

Sq M 0,959

That is rather thick pieces of aluminum. At 90mm square they will visually reflect a lot bigger than 50mm square tubing. Stand will look a lot beefier although not sure if stronger. Most likely lighter.

Cost wise, I tend to think that these aluminum tubes will cost more than 50mm square tubing with 3mm wall thickness. You can always galvanize the steel stand. The steel stand on its own will weigh a lot more.

Not a lot of use to you but the redsea 650l tank frame is made out of 20x20 ali...thats 1.6m x 0.7.......Has 2 sub frames 0.5 apart...one of their installation manuals has some reasonably detailed viewing of the frame design if its of use.

T Slot looks awesome and is incredibly strong. Just a very expensive option when you work it out. Just the corner brackets, T slot nuts and bolts etc add a hefty chunk to the overall price. To reduce the cost, you could rather opt for the 90x45 option and fit them vertically orientated. Would give you the same strengthas a 90x90 in the vertical direction. Check out this link.

Also you can go to the 20/20 inc website and download their free "Tech toolkit" software package. will tell you all the strength modulus ratings and evens tells you how much a beam will flex under different weights. Just be sure to select the metric options.

Thanks for the link. The cost is much more, but i like the look and I have had steel stands before, but they rust too quickly even when coated.

Yes, unfortunately rust is something that goes with the hobby! Aluminum corrodes as well remember, so be sure to go for the anodized finish as that will help to some degree. But I agree that it is a nicer looking option.
