Moreover, cold rolled steel shows superior strength characteristics. The work hardening that occurs during the cold rolling process increases its hardness, making it suitable for applications that require additional strength without the need for further processing. This property is particularly advantageous in the automotive industry, where cold rolled sheets are commonly used for body parts, frames, and structural components.
The roll forming process begins with unwinding a metal coil, which is then fed into the forming section of the machine. As the strip moves through the series of rollers, it undergoes deformation, gradually taking on the desired shape. Advanced roll forming machines may incorporate additional features, such as hydraulic systems for managing pressure and ensuring smooth operation. Once the profiling is complete, the formed strip is usually cut to length using automated shears, resulting in a finished product ready for shipment or further processing.
