The difference between cold rolled sheet and steel sheet

Cold plates and steel plates are not the same. Although they are used in the machinery industry, they are different in terms of materials and specifications, so we must distinguish them in some aspects.

Cold plate is the abbreviation of cold-rolled plate. Cold-rolled coil is made of hot rolled coil and rolled at room temperature below recrystallization temperature, including plates and coils. Many domestic steel mills such as Baosteel, Wuhan Iron and Steel, Anshan Iron and Steel Co., Ltd. Can be produced. Among them, the steel sheet, also called the box plate or the flat plate, is called a steel strip, also called a coil plate. The specifications of the cold plate are generally 0.2-4 mm in thickness, 600-2 000 mm in width, and the length of the steel plate is 1 200-6 000 mm. The cold plate is mainly made of low carbon steel grade, which requires good cold bending and welding performance, as well as certain punching performance.

The steel plate is a flat steel material which is poured with molten steel and pressed and cooled. The steel plate is flat and rectangular and can be rolled directly or cut from a wide steel strip. The steel plate is divided into thicknesses, thin steel plates <4 mm (the thinnest 0.2 mm), thick steel plates 4 to 60 mm, and extra-thick steel plates 60 to 115 mm. The steel plate is divided into hot rolling and cold rolling. There is also a material for the steel plate. Not all steel plates are the same, the materials are different, and the places used for the steel plates are different.
