Hello At The top of the advertisement, the first description says, stainless steel …. Then below , it says about this product…. It says heavy duty steel , powder coated, to protect against rust , resist scratches ect…NOTE: (from me..the Buyer) stainless steel is good for prevention of rust, corrosion ect…so which one is it….?? Stainless Steel or just metal with a black coating….I prefer Stainless Steel, and I don’t want to have to return it… Thank you , The Buyer
