Product type
Cold rolled annealed sheets are flat products made from carbon steel that undergo a cold rolling process followed by annealing. This process enhances the mechanical properties of the steel, resulting in improved strength, ductility, and surface finish. The sheets are typically smooth and have a uniform thickness, making them suitable for various applications in manufacturing and construction.
| Material | Carbon steel |
| Thickness range | 0.5 mm to 3.0 mm |
| Width range | 600 mm to 1500 mm |
| Length range | 1000 mm to 3000 mm |
| Surface finish | Smooth, with minimal defects |
| Mechanical properties | Yield strength 250 MPa to 400 MPa |
When choosing cold rolled annealed sheets, consider the specific mechanical properties required for your application, such as yield strength and ductility. Specify the desired thickness, width, and length based on your project needs. Additionally, inquire about surface finish requirements and any relevant certifications that may be necessary for your industry standards.

Cold rolled sheets are processed at room temperature, resulting in a smoother finish and tighter tolerances compared to hot rolled sheets.
Yes, they can be welded, but it's important to consider the specific welding techniques and filler materials suitable for carbon steel.
Common grades include ASTM A1008 and SAE J403, which vary in mechanical properties and applications.
They should be stored in a dry environment to prevent rust and corrosion, ideally on pallets to avoid contact with the ground.
Yes, common surface treatments include galvanizing, painting, and coating to enhance corrosion resistance.
Lead times can vary, but typically range from 2 to 6 weeks depending on the supplier and order quantity.
