What is steel plate

        Steel plate is a flat steel with a large aspect ratio and surface area. The steel plate is divided into two types: thin plate and thick plate according to the thickness. Thin steel sheets are steel sheets with a thickness between 0.2-4mm produced by hot rolling or cold rolling. The width of the thin steel plate is between 500-1400mm. According to different uses, the thin steel plate is rolled from billets of different materials. 

        Commonly used materials are ordinary carbon steel, excellent carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. They are mainly used in the automotive industry, enamel industry, electrical industry, machinery industry and other sectors. In addition to direct delivery after rolling, thin steel sheets are also available in pickling, galvanized and tin-plated. Thick steel plate is a general term for steel plates with a thickness of more than 4mm. In practical work, steel plates with a thickness of less than 20mm are often called medium plates, steel plates with a thickness of >20mm to 60mm are called thick plates, and steel plates with a thickness of >60mm need to be specially It is rolled on the extra-thick plate mill, so it is called extra-thick plate.
        The width of thick steel plate is from 0.6mm-3.0mm. Thick plates are divided into shipbuilding steel plates, bridge steel plates, boiler steel plates, high-pressure vessel steel plates, checkered steel plates, automobile steel plates, armored steel plates and composite steel plates according to their uses. A branch of the steel plate is the steel strip. The steel strip is actually a very long thin plate with a relatively small width. It is often supplied in coils, also known as strip steel. Steel strips are often produced on multi-stand continuous rolling mills, and are cut to length to form strips, so the productivity is higher than that of a single-sheet machine.
