potawie, if you're talking about the exaclibur the manufacturer sells stainless shelves for it. they also have heavy duty commercial stainless line but they're waaaaay expensive.
Great units although they don't have stainless steel shelves and if I'm going to buy a commercial unit it should be up to commercial standards
Try LEM stainless steel dehydrators, and they come with nickel shelves (which is foodsafe and nickel is in stainless steel) or you can buy SS.
