Diamond Floor Plates

Also known as steel tread plates or steel diamond plates, steel floor plates have a diamond lug pattern designed for skid resistance. This makes them ideal for trailer decking and truck beds, as well as running boards, walkways, stair treads, and ramps. They can also add adequate protection to warehouse doors and hallways from heavy machinery and carts.
