Checkered steel plates, or diamond plates, are textured steel plates that reduce the risk of slipping. This is done by producing a diamond plate as a solution for stairs, catwalks, walkways, and ramps in industrial areas. It is also used in vehicles to prevent slipping on the metal which otherwise would be slippery, especially in wet situations. These steel plates with concave and convex surface patterns on the surface is most prominent in transportation, construction, decoration, equipment, flooring, machinery, shipbuilding, and other industries. They are produced using a technique where the surface pattern is hot rolled onto the steel plate.
