    O.K... most of us have great looking display cabinets for our display tanks...but what to do when MTS hits and you on a budget...and cant weld?

    Came across this guy who has thought out the box a bit and who's products suit stand building down to a "T"...
    Check this out: http://freeadz.co.za/Shop/index.php?cPath=22

    25mm square tubing is quite strong and I'm sure will be able to hold a tank or two...especially compared to those cheap and nasty el cheapo angle iron monstrosities you see for sale for standard size tanks in your local LFS...

    Thank you - you're welcome :)

    Questions is...who's gonna test it? LOL

    Not quite sure if they'll handle the weight of multi tier racks?

    I'll be testing it quite soon - seems a viable option compared to the quote i got for welding up my planned 3 ton breeding wall stand... gonna have an engineer buddy do the math for me (eish - why does bribe beer cost so bloody much?)
    But think this will be super strong...have worked in quite a few shops over the years where aging angle iron welded frames carry close on a ton of aquariums each, so working with square tubing should be even stronger (?)

    Came across this on FB and see the guy is from Pretoria...hopefully can go see him and have a chat - will give feedback when and If...

    My breeding rack is also made out of square tubing, but welding "melts" the iron...was wondering how strong these joints are

    Interesting. In any simply supported beam case the centre of the beam has the maximum bending moment (and max deflection) and the ends have max shear. The clamp is relying on friction to keep the beam ends from slipping out and would probably do a reasonably decent job - how effectively I cannot say, that would depend on clamping force.

    If you stuck in two square tubes they would (I am guessing) be slightly further apart than corner to corner. You would want the horizontal member resting effectively on the vertical member but I suspect highly that this is not the case. Which means that these corners units must also be able to take the vertically down force that exists at the ends. The best test would be to assemble a basic stand and then apply a known load - a few fat, beer drinking buddies sitting on a piece of plywood would be a crude but possibly effective test (depending on their aversion to sport) and see what it does. There would be some risk in using the heavy loads of fish tanks without testing it first somehow, and one could assume it may have been designed for drills, dust gathering barbie dolls and annoyingly useless decorations you thought were cool 10 years ago.

    Conclusion: could work nicely! I would be keen to try this myself, especially for a garage storage setup, however I would be cautious of loading this system up in a heavily loaded system.

    Thanks for the link!!!! I enjoy welding and have done so on several and shelves and my tank stand but often time is an issue :)

    Well look at the Ixx and Iyy (2nd moment of inertia) values between different sections and you've got more of an idea already ;-) I'm a mechanical engineer. :eyeroll: I never watched but this may be useful:

    but in the long run and if you have bucks, I think something like this.. industrial racking systems! also can sell it off easier when you don't need it anymore.

    If those connectors are made from LDPE or HDPE plastic I would not trust them at all to hold a tank, never mind multiple tanks in the same stand. --- sorry my bad...

    "is manufactured from an integral sheet metal stamping."

    Now it all depends on the thickness of the sheet metal - but I reckon if the fit is tight and neat without too much movement it could possibly work.
    and by the way, a welded joint is only as good as the welders skills, learnt that the hard way

    Storage Direct sells those industrial ones. But unless you recently sold off both your kidneys, you might have to rob a bank.
