It's a good idea to not stow the GI metal cans on bare concrete, as they seem to "wick up" moisture from the concrete and rust out (if slowly).
Last year I built some shelves in my storeroom to hold ammo cans. I used cinder blocks and 2X6's and I put a strip of plywood on the floor for the bottom layer to sit on. My storeroom is heated and air-conditioned so it may have been overkill.
