带钢（Strip steel） Strip steel Nbsp; strip steel is a narrow, long steel plate that is produced to meet the needs of different industrial sectors. Strip steel, also known as strip steel, its width is generally less than 300mm, but with the development of the economy, the width has no limit. The steel strip coil supply has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Same as the steel plate, the strip is divided into two kinds: ordinary strip steel and high quality strip steel according to the material used, and two kinds of heat and cold rolling according to the processing method. Widely used in the production of welded steel pipe, made of cold formed steel billet, manufacturing bicycle frame, rim, clamp, gasket, spring, saw blades and blades and so on. (1) hot-rolled ordinary strip steel 1, hot-rolled ordinary carbon structural steel strip (GB3524-83) The hot rolled carbon steel strip is made of ordinary carbon structural steel and is rolled into strips with a thickness of 2.00-6.00mm and a width of 50-300mm. (1) main uses Mainly used for cold rolled billets, cold formed steel billets, welded steel pipe billets and bicycles, hardware products. (2) the grade, chemical composition and mechanical properties of the material Comply with the requirements of GB700-79 (88). 2. Hot rolled wide strip steel for cycling (GB3645-89) Hot rolled wide band steel for bicycles, made of carbon steel and low alloy steel, rolled to a thickness of 2.0-8.0mm steel by hot rolling, with a strip width of 1300mm. (1) main uses Used exclusively for bicycle making materials. (2) the grade and chemical composition of the material (3) mechanical properties (4) specification and size of strip (board) Strip thickness 2.0-6.0mm, steel plate thickness 7, 8.0mm. The strip width (plate): rimming steel is less than or equal to 1300mm (a=2.0-6.0) Killed steel is less than or equal to 1250mm (a = 3) = 1300mm (a = 3) Steel plate length: steel coil in
