I have seen a lot of builds for DIY storage tanks as well as indoor koi ponds that seem to use wood, typically 2x6 on edge 6" OC bolted together and tied together with plywood on either side, and I was thinking of using scrap C Channel I have left over from building.
The C Channel is 16ga, 2x4x4 and I have it in lengths at least 11ft long, at most 12ft long. With a ~7.5x7.5x4ft tank I think I can get about 900 gallons insulated with 4" polyiso in between the channels and another 3/4" polyiso inside the tank to protect the liner from the screws. I am thinking 16" OC horizontally and screwing the sides where the channel overlaps with a couple tek screws (top/bottom) and maybe even putting a piece of sheet metal inside the C Channel to better protect the foam and provide more rigidity (could be overkill) ... I could add more sheet metal on corners to help tie the channels together as well.
I got a quote on a 1000gal insulated tank from a good manufacture of soft tanks, with two coils it was like 8k 0__0 I already own a bunch of 4" polyiso and this left over C Channel so figured I would DIY it.
I tried to do load calculations for this but I am not a structural engineer :/
Anyone ever do something like this with steel?
