Steel flat plate: A type of flat steel plate, usually with a smooth surface and uniform thickness. It is made by rolling or forging processes of steel billets and has higher strength and toughness. Steel flat plates are widely used in manufacturing, construction engineering, machinery and equipment, and other fields, such as manufacturing auto parts, ship structures, bridge construction, etc. Checkered steel plate: A steel plate with various patterned designs pressed on the surface of the steel flat plate. These patterns can provide good anti-slip performance and are often used in places that require anti-slip, such as stair treads, platforms, walkways, etc. Checkered steel plates can also increase the surface hardness and wear resistance of the steel plate, making it have better performance in some special applications.
