Hi just finished talking to my local steel guy

. I wanted to try using a sheet of steel in my oven on the lower rack to create a pizza oven effect. But I was informed that I could damage my oven by creating to much heat and burn up the element.
Has anyone experience a problem with the tiles doing this? I wanted to try the steel and see if I could get the same results as a pizza oven made with steel instead of brick. Still think I could do this just can't seem to get my friend to supply me with a sheet of steel the appropriate size for my oven.
