Cold Rolled Carbon Steel Coils

At Baoli Iron Steel, we specialize in providing premium Cold Rolled Carbon Steel Coils, engineered for applications demanding superior surface finish, precise dimensions, and enhanced mechanical properties. Our cold rolled coils are meticulously processed from hot rolled coils at room temperature, undergoing a series of rigorous cold reduction, annealing (where applicable), and temper rolling operations. This advanced manufacturing process refines the steel’s microstructure, resulting in a product that significantly outperforms hot rolled alternatives in critical aspects.

Key Features & Advantages

• Superior Surface Finish: Achieves a smooth, clean, and bright surface, ideal for aesthetic applications and subsequent coating processes like painting, electroplating, and enameling. The improved surface quality minimizes imperfections, leading to a pristine final product.
• Exceptional Dimensional Accuracy: Offers significantly tighter tolerances on thickness, width, and flatness compared to hot rolled steel. This precision is crucial for automated manufacturing processes and applications requiring exact component fit.
• Enhanced Mechanical Properties: The cold rolling process increases the steel’s tensile strength, yield strength, and hardness, while maintaining good ductility and formability. This makes our coils highly resistant to deformation and wear, suitable for challenging structural and forming applications.
• Excellent Formability & Workability: Despite increased strength, our cold rolled coils retain excellent formability, allowing for complex bending, deep drawing, and stamping operations without cracking, making them versatile for intricate designs.
• Consistent Quality: Each coil undergoes stringent quality control checks to ensure uniform mechanical properties and dimensional consistency throughout the batch, ensuring reliability and reducing production waste for our clients.
