Product type
Cold rolled coils (CRC) are flat steel products that are produced by rolling steel at room temperature, which enhances their strength and surface finish. This process involves passing the steel through rollers to achieve the desired thickness and surface smoothness. Cold rolled coils are typically made from low carbon steel, high carbon steel, or alloy steel, depending on the application requirements. They are widely used in various industries due to their excellent surface quality and dimensional accuracy.
| Thickness range | 0.3 mm to 3.2 mm |
| Width range | 600 mm to 1500 mm |
| Yield strength | Up to 600 MPa |
| Surface finish | Bright or matte finish |
| Coil weight | Up to 30 tons |
When selecting cold rolled coils, buyers should consider the specific grades of steel required for their application, as different grades offer varying mechanical properties. It's also important to specify the desired thickness, width, and surface finish to ensure compatibility with production processes. Certifications such as ISO or ASTM standards may be relevant, depending on the industry. Additionally, buyers should determine the quantity needed, as this can influence pricing and availability.
