Strip steel is a narrow and long steel plate produced by various steel rolling enterprises in order to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, has a width within 1300mm, and the length varies slightly depending on the size of each roll. Steel plates with thin thickness, narrow width and long length. Its width is generally 20mm-200mm. Supplied in rolls, the specifications are expressed in thickness x width. According to the quality of the steel, it is divided into high-quality and ordinary strip steel; according to the rolling method, it is divided into two types: hot rolling and cold rolling, which are called hot-rolled strip steel and cold-rolled strip steel respectively. The thickness of hot-rolled ordinary strip is 2mm-6mm, and the thickness of cold-rolled strip is generally 0.05mm-3.60mm. Strip steel can be made of plain carbon steel, carbon structural steel, spring steel, tool steel, stainless steel and other steel types. Widely used in manufacturing welded pipes, clamps, washers, spring blades, saw blades, blades, etc. Strip steel is generally supplied in rolls and has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving.
