Introduction to Steel Coil
Steel coil, also known as rolled steel, is a fundamental product in the steel industry. It is produced by rolling steel sheets or strips through a series of processes. Steel coils come in various types, including hot - rolled steel coils and cold - rolled steel coils. Hot - rolled steel coils are made by heating the steel above its recrystallization temperature and then rolling it, which results in a product with good ductility and relatively low cost. Cold - rolled steel coils, on the other hand, are produced by further processing hot - rolled coils at room temperature, offering a smoother surface finish, higher precision, and better mechanical properties. Steel coils are widely used in many industries such as automotive, construction, manufacturing, and shipbuilding.
