When you have a heating element under the floor, the floor essentially becomes the heating element. By placing the foil on the floor, the heat will conduct directly to the foil in such a way that the foil will just become an extension of the floor, and not become the heat deflector that you're looking for.
On the shelf where the steel is sitting, you can put a curve in the foil, fold over the ends into hooks and hang it, like a hammock from shelf wire to shelf wire. That will take it off the floor but still provide a little air between the foil and the steel.
