1.2m glass thickness

[Brad Cottle]

Hi guys I was planing on building a 1200x800x600 mm tank (lxbxh) but I want to go rimless or as close too what would you recommend for the thickness of the glass I would like the water level to be at 550mm what are your recommendations or ideas thanks

15mm will work

Does "rimless" mean no bracing?
If you are planning/willing to put something like euro bracing, then 10mm will suffice.
I don't have the links now, but there's a lot of websites with calculators for this question. Google is your friend!

15mm would be best

12mm is good, i have the same size and so does @butcherman
i would however make a double floating base

12mm will give to a strength rating of 4.4 for sides and 11 for double base

mine is a little shallower ... and the 12mm is going nowhere !! (plenty of glass)

Thanks guys I have calculated it but better be safe than sorry so if water level is at 550mm will 12mm be fine? Without bracing

 

[leslie hempel]

While the tank wouldnt necessarily crack. It will bow with 12 mm and no bracing at that height im sure..

550 with water at 500?
