So my wife is going to get me a steel plate as a Christmas gift. I currently use a baking stone. From reading the threads, it sounds like it might make sense to use a local fabricator here in Maryland/DC rather than going with Baking Steel, both for cost and customization reasons. I measured my oven, and it looks like it can fit an 18 by 15 inch slab. So I am thinking of getting two 9 x 7.5 x 1/2-inch slabs of hot rolled A36. Besides getting them sandblasted, is there anything else I need to do before cooking pizza or other food on them? And any suggestions for a local fabricator?
