    Hi Guys,

    I am new to the forum but I need some advise.

    I am busy building a steel stand for my custom 1300 x 600 x 600 tank. I am using 38mm square tubing (1.6mm wall thickness). What I would like to know, will this be sufficient to hold the tank?

    Stand dimensions:
    1300 x 600 x 950 (LxWxH)

    I have attached a picture :)

    Your advise will be appreciated!

    Welcome to MASA,

    I have moved your post to a new thread.

    I am no engineer but i would offer 2 suggestions.

    1 increase the wall thickness to 2mm

    2 remove that front vertical brace (you will thank me later for this one, you will need to get under the tank to do propper maintenence ~!!)

    Remove the front piece and add gussets in the corners of the front.

    you are looking at about 468 lt of water plus your live rock plus you gravel , depending on your live rock amount lets say 30kg you will need about 40kg gravel you looking at a total of 538kg inside your tank that is not including the tank itself , i would go for a 50mm square tubing with a thicker wall and brace the corners for side movement,

    i hope this is correct

    Hi, my stand is like that except it is 1000mm and not 1300mm. Mine is from 50mm sq tube with 2mm wall, Iniatially i wanted 38mm but changed to 50mm - overkill but i sleep well.
    The center leg is not a problem for me but then again i'm small build so bigger oaks might have a problem. The height is good as you have a nice viewing height and space to work in the engine room but if you are a shorty you going to use a 2-step most of the time.

    Even if you are tall, the top of the tank will be at around 1.9m. That's is huge.

    Thanks everyone for all the comments.

    The problem is that I have started with the stand already :( If I add the braces and leave the center legs (don't think they will bother me too much) like the picture below, do you guys think I will be ok?

    this design will work, i would still cut the front middle leg out the way, or make it removable using a bolt etc

    I would remove the middle front leg and use 38x38x2 tubing with a 100x50x3 tubing across the top in the front. I wouldn't worry about gussets, as long as the welding is done properly.

    My stand is 1.4x0.6x1m (LxWxH), its made with 38x38x2 and its extremely stong even without gussets. I do have middle leg, and I wish I didn't!

    Your second stand design is much better, I would echo to remove the centre upright of the front of the stand. Also make the top beams rectangular with the longger side facing down, much stronger this way(38x50), but if you've already made it then its also okay. I would also recommend to add the gussets, you dont need such heavy gussets as you've shown, just 3mm plate welded into the top corners both ways like little triangles(100mm horizontally and vertically welded. If you ever fit a wavemaker then your stand will hold up against side sway movement which will prevent flexing of your tank glass. Excessive flexing means cracked glass :-(

    Hi Guys,

    Ok, my stand is finished (I will post photos later). I am just a bit concerned about the strengh of the stand. It will only support the tank (450L) as the sump is on the floor but I've used 38 x 38 x 1.6mm square tubing... I have added the braces so my stand looks exactly like the picture below without the front middle beam.

    Do you guys think it will hold? I am scared it collapses in the front middle section because of the missing support? Please let me have your thoughts..!

    Welcome dude , your stand would have worked even the original design, would have been plenty strong my tank of same size is on a 25 x 25 x 1.6 and there is the sump and QT tank on this stand and its just over 1 m tall, but hey now you have a place of saftey to hide under when the shit hits the fan..........LOL

    looks good, the strength will lie in good welding
