Cold-rolled steel sheet
Cold Rolled Coil/Sheet (CRC) is a steel product manufactured from hot-rolled pickled coils, which undergo cold rolling at room temperature via a cold rolling mill, followed by further processing steps such as annealing and leveling. Thanks to the unique characteristics of its production process, CRC boasts excellent surface quality, high dimensional accuracy, and superior mechanical properties—making it a critical foundational material for high-end manufacturing and advanced precision processing applications.

Detailed introduction
Key Features
Exceptional surface quality: The surfaces are smooth and flawless, free from iron scale and rust, resulting in a beautifully refined appearance. We can provide various grades to meet your needs, ranging from standard finishes to ultra-high-quality surfaces—such as O5/FB sheets, ideal for premium automotive interior components.
High-precision dimensions: Thickness tolerances are tightly controlled, ensuring excellent consistency in width and flatness—making it ideal for high-accuracy stamping and forming processes.
Excellent mechanical and processing properties: By adjusting the manufacturing process, varying levels of strength, hardness, and ductility can be achieved. It exhibits excellent stamping and bending performance, making it easy to weld.
Versatile post-processing capabilities: It serves as an ideal substrate, easily accommodating advanced processes such as electroplating (zinc plating, tin plating), color coating, and film lamination.
Main application areas
Cold-rolled coil steel, thanks to its excellent overall performance, is widely used in industries with high demands on surface quality and formability:
Automotive manufacturing: Exterior body panels such as the car body, doors, hoods, and trunk lids, as well as internal structural components.
Household appliances: Panels and casings for appliances such as refrigerators, washing machines, air conditioners, microwave ovens, and more.
Electronic products: Metal components for computer cases, servers, and various types of electronic devices.
Architecture and Decoration: Light steel framing, interior partitions, ceilings, security doors, and more.
General Hardware: Manufacturing of various metal products, including furniture, filing cabinets, toys, lighting fixtures, kitchenware, and more.
Common Specifications and Grades
Material grade:
Standard Grade (SPCC/DC01/ST12): Typically used for bending and simple forming applications.
Stamping grade (SPCD/DC03/ST13): Offers superior ductility and is used for general-purpose stamped parts.
Deep-drawing grade (SPCE/DC04/ST14): Offers excellent deep-drawing performance, making it ideal for producing stamped parts with complex shapes.
Specification range:
Thickness: Commonly available in 0.3mm to 3.0mm—thinner or thicker specifications can be produced upon request.
Width: 600mm – 2000mm (depending on mill capacity).
Delivery options: Steel coils (inner diameter 508mm/610mm) or flat plates (fixed-length steel sheets).
The advantages of choosing cold-rolled coil steel
Enhancing product quality: Excellent surface finish and dimensional accuracy ensure high-quality aesthetics and structural stability for the final product.
Improving production efficiency: Excellent formability reduces scrap rates and downtime during the manufacturing process.
Reducing overall costs: Although the unit price may be higher than that of hot-rolled steel, its superior formability and excellent post-processing performance can help lower overall manufacturing costs.
Environmental friendliness meets aesthetics: Clean surfaces are better suited for eco-friendly treatments like electroplating and spraying, resulting in products that are both more visually appealing and long-lasting.
