Type 304 stainless steel is a food grade Stainless, most commonly seen in commercial kitchens as back splashes, corner guards and C-Channel. It is also used for door kick plates, as well as in schools, hospitals and other food industries where sanitation and cleanliness is a must. Every piece of our Stainless Steel sheets come with a protective plastic paper on one side to protect the finish during fabrication and installation. You peel it off after everything is safely and properly in place, to reveal a perfect scratch free finish. Grade 304 Stainless Steel is austenitic [aw-stuh-nit-ik], meaning it will not attract or hold a magnet.
