Product Overview
Cold Rolled Steel Coil (CRC) is a high-quality steel product manufactured by pickling hot rolled coils to remove surface scale, cold rolling to target thickness at room temperature, followed by continuous annealing, tempering, and finishing processes. Compared to hot rolled products, cold rolled coils offer superior surface finish, tighter dimensional tolerances, more consistent mechanical properties, and excellent formability, making them an ideal substrate for precision manufacturing, automotive industry, home appliance production, and various applications requiring high-quality surfaces
Product Features
1：Superior Surface Quality
Through pickling and precision rolling processes, cold rolled coils feature a smooth and bright surface free from scale, rust, and obvious defects. Various surface finishes including 2B bright, dull finish, and oiled/dry condition are available upon request, providing an ideal substrate for subsequent painting, plating, and lamination.
2：Precise Dimensional Tolerances
With high-precision cold rolling technology and strict automatic gauge control systems, the product maintains excellent dimensional accuracy in thickness, width, and flatness. Thickness tolerance can be controlled within ±0.03mm, effectively improving material utilization and production efficiency for downstream users.
3：Excellent Formability
Through optimized chemical composition design and annealing process control, cold rolled coils exhibit excellent ductility and plasticity, suitable for various deformation processes such as stamping, drawing, bending, and roll forming. Based on application requirements, products ranging from commercial quality (SPCC/DC01) to extra deep drawing quality (SPCEN/DC06) are available to meet diverse applications from simple bending to complex deep drawing.
4：Consistent Mechanical Properties
Continuous annealing and tempering processes ensure uniform and stable mechanical properties throughout the coil. Strict process control and inspection systems guarantee consistent yield strength, tensile strength, and elongation, meeting the consistency requirements of various application scenarios.
5：Excellent Weldability
The low carbon content design ensures good weldability of cold rolled coils, with high compatibility with common welding technologies such as spot welding, arc welding, and resistance welding, simplifying downstream manufacturing processes.
