Cold Rolled Steel Coils
01. Product Overview
Our Cold Rolled Steel Coils provide a practical material choice for manufacturers requiring controlled thickness, smooth surfaces, and consistent material properties for metal processing.
Produced by reducing hot rolled steel through cold rolling, these coils offer improved dimensional control and a smoother surface. They are used in stamping, bending, roll forming, sheet metal fabrication, and other manufacturing processes where material consistency and surface condition matter.
We supply cold rolled steel coils in different grades, material conditions, and surface finishes to match the requirements of the finished component and its manufacturing process.
Key Product Advantages
- Controlled Dimensions: Improved thickness and dimensional control support accurate cutting, material feeding, and component forming.
- Smooth Surface: A smoother surface provides a suitable starting material for painting, coating, and other finishing processes.
- Grade Selection: Commercial, drawing, and deep-drawing grades allow selection according to forming requirements.
- Coil Supply: Continuous coil format supports production processes involving stamping, roll forming, and other coil-fed operations.

For accurate material selection, we consider the specified grade together with thickness, delivery condition, and required mechanical properties.
03. Surface Finish & Material Condition
Surface finish determines the required material appearance and surface condition, while material condition is selected according to the intended forming process.
Surface Finish and Protection
- Bright Finish: Available for applications requiring a bright surface appearance.
- Dull Finish: Available for applications with different surface appearance requirements.
- Oiled Surface: A protective oil film helps reduce corrosion during storage and transportation.
- Dry Surface: Supplied without the protective oil film, according to the specified surface requirement.
Material Condition
We offer different material condition options according to grade availability and processing requirements:
- Soft: Selected for applications requiring greater formability.
- Half Hard / Hard: Selected according to the required hardness, strength, and forming process.
- Full Hard: Used where the material's hardness and mechanical properties are suitable for the intended processing operation.
Edge and Dimensional Requirements
Mill-edge and slit-edge options can be specified according to the required coil configuration. Thickness tolerance, width tolerance, and flatness should also be established before ordering to match downstream processing requirements.

06. Applications of Cold Rolled Steel Coils
Cold rolled steel coils serve a range of manufacturing applications requiring controlled dimensions, suitable forming properties, and consistent surface conditions.
| Application | Main Selection Considerations |
|---|---|
| Automotive Components | Steel grade, thickness, elongation, and forming requirements |
| Home Appliance Housings | Surface finish, thickness, and subsequent coating requirements |
| Metal Furniture | Material condition, thickness, and bending requirements |
| Electrical Cabinets and Enclosures | Width, thickness, flatness, and fabrication requirements |

07. FAQ & RFQ
What is the difference between SPCC, SPCD, and SPCE?
SPCC is commonly used for commercial-quality cold forming, SPCD is intended for drawing applications, and SPCE is designed for deep-drawing applications. The appropriate grade depends on the forming requirements of the finished component.
What is the difference between DC01, DC03, and DC04?
DC01 is commonly used for general cold forming, DC03 for improved drawing requirements, and DC04 for more demanding deep-drawing applications. Buyers should select the grade according to the applicable EN 10130 requirements.
Should I choose oiled or dry cold rolled steel coils?
Oiled coils have a protective oil film that helps reduce corrosion during storage and transportation. Dry coils are supplied without this oil film. The choice depends on storage conditions and subsequent processing requirements.
What coil inner diameters are commonly used?
Common industry options include 508 mm and 610 mm. The required inner diameter and individual coil weight should be specified according to the intended handling and processing requirements.
Can I specify mill-edge or slit-edge cold rolled steel coils?
Mill-edge and slit-edge requirements can be included in the order specification. The required edge condition should match the intended coil configuration and subsequent processing.
What information should I provide for a quotation?
