Strip steel is a narrow and long steel strip produced by various steel rolling enterprises in order to meet the needs of industrial production of various kinds of metal or mechanical products in different industrial sectors. It is within 1300mm in width and the length is slightly different according to the size of each roll
Strip steel is usually supplied in rolls and has the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. Same as the steel plate, the strip steel is divided into ordinary strip steel and high-quality strip steel according to the material used; according to the processing method, it is divided into two types: hot-rolled strip steel and cold-rolled strip steel.
Strip steel is widely used in the production of welded steel pipes, as billets forcold-formed steel, produce for bicycle frames, rims, clamps, washers, spring blades, saw blades, hardware products and blades and so on.
The hot-rolled plain carbon strip steel is made of ordinary carbon structural steel, and be hot-rolled into strip steel with a thickness of 1.80-6.00mm and a width of 50-1200mm. Mainly used for the manufacture of cold-rolled billets, cold-formed steel billets, welded steel pipe billets, bicycles, and small hardware products. The cold-rolled high-quality carbon strip steel is made of high-quality carbon structural steel and obtained from cold-rolled. Because cold-rolled strip steel can be rolled thinner than hot-rolled strip steel, and has higher dimensional accuracy and higher strength, thinner cold-rolled strip steel is often used instead of thicker hot-rolled strip in the same application, which can save about 30% of steel. According to the manufacturing precision, it can be divided into four types of strip steel: ordinary precision (P), higher width precision (K), higher thickness precision (H) and width and higher thickness precision (KH). According to the material state, it can be divided into two types: chilled and annealed. The former has higher strength and the latter has good plasticity and toughness.
