I work around these things now and then. The plastic containers are quite solid, but it can be difficult to wash out whatever was in them. The sort of stuff I work around is not the kind of stuff I want to bring home. Sometimes I discard my clothing. The aluminum frames are handy, but wont take much load. They are not made to stack. I've used them to store air hoses-roll em up, duct tape em together, toss em in the bin. Makes moving with a forklift a breeze. The base is a durable plastic, but it is formed for the container drain.
The frame would hold up well sitting outside for years. Take out the container and the bottom, you've got an instant
compost or leaf mold bin.
Leave the bottom on, flip it over, dig or cut an entry, it will serve as a small livestock
shelter. Surround with
hay and leaves for a winter shelter.
If the previous contents is not poison, these are awesome for thermal storage tanks. Has a 2" drain on the bottom with valve. Top has a bung to add 2" plumbing as well as a screw on lid about 6" across. Capacity is about 250 gallons. Filled with
water, about 1000#. I would not want to drink the water.
I knew an Amish fellow who had one of these, used it as a holding tank. Put a bobble valve on the top to keep it full, filled it from an artesian well, ran the plumbing to serve his house. He raised it about 8 feet off the ground to get better pressure. Probably still using it.
