Cold-rolled steel coils
Cold-rolled steel coils are steel products that have undergone a cold rolling process. Cold rolling is a manufacturing process in which hot-rolled steel is passed through rollers at room temperature, compressing and shaping it into thinner and more precise coils.
During cold rolling, the hot-rolled steel is first pickled to remove any scale or impurities on the surface. It is then passed through a series of rollers that apply pressure, reducing the thickness of the steel and improving its surface finish. This process also increases the strength and hardness of the steel.
supplies Cold Rolled Steel Coil Product suitable for wide Applications, main standard include JIS G3141, EN10130, EN10268, GB/T5213.
Cold rolled steel coil can be slit into any size with a width of <=1430mm(coil slit) according to customer's requirements; it can also be uncoiled and cut to length(cold rolled steel sheet) ,
our steel mill is equipped with high class uncoiling and straightening production line to guarantee the product quality. Custom package is also available.
