Diamond plate is also known as checker plate and tread plate, it is a type of metal stock with a regular pattern of raised diamonds or lines on one side, with the reverse side being flat. Diamond plate is usually steel, stainless steel or aluminum. The texture of diamond plate reduces the risk of slipping, making it a solution for stairs, catwalks, walkways, and ramps in industrial, manufacturing and other factory settings. The non-skid properties also make it ideal for use in ambulances and on the footplates of firetrucks and truck beds. This type of metal is also used for decorative purposes on walls, trucks and jeeps and in products like tool boxes.

Mark Metals carries a wide variety of sizes and weights in aluminum, stainless steel and carbon steel.
