304 stainless steel floor plate, also known as “tread plate” or “diamond plate”, is an excellent candidate for most processing techniques as well as both indoor and outdoor applications. This product has a textured dull grey finish with a raised diamond pattern to provide all around traction. Stainless steel floor plate has a hot rolled, annealed and pickled (HRAP) finished surface. Its high strength properties and excellent corrosion resistance make it the perfect candidate for catwalks, trench covers, walkways, and ornamental projects. ASTM A793 is the standard specification for stainless steel rolled floor plate.
