I'm no expert, but I would think, if something that can be affected by moisture is to be put in a permanent location, there should be some kind of barrier between it, and the floor. A small piece of vapor barrier or something. Basement floors have a bit of dampness to it which will eat at metal, and wood. Wood will eventually rot, metal will rust, as seen.
And yeah very odd location for a support, it may not even be needed.
