   cold rolled steel coil

Brief Introduction: As the name suggests, steel is processed while cold. It is manufactured from hot rolled coil that has been chemically cleaned before being rolled. The coil is initially cold, however while being reduced, the coil will get hotter as the steel work hardens.  
The cold rolling reduces the thickness of the steel and at the same time changes the mechanical properties of the steel. Cold rolled steel must be further processed, as the steel will react with water in the air and form rust. In most cases, it is covered with a thin layer of oil to prevent oxygen reacting with surface.Grade : Q195L/SPCC/DC01Thickness:0.4-2.0mmWidth:1000-1250mmStandard: GB/T11253-1989;JIS G 3141-1996 SPCCApplication: The steel coils can be annealed (heated in a controlled atmosphere) to make the steel more formable (cold rolled annealed) or further processed on the metallic coating line, with a coating of either zinc (galvanized) or zinc-aluminum alloy (ZINCALUME® steel) applied. Cold rolled steel is available in a range of grades, each with a range of properties for differing applications. Like the Zinc-coating base plate, Construction and Furniture, Automotive manufacturing, electric equipments, vehicles, aerospace, precision instrument, food cans, etc.Process Flows: Hot rolled steel coil---acid picking---rolling---annealing---level up---tension leveling---cutting---oiling---coldrolledsteel coil---weighing---inspecting---packing---accessing warehouse
