DC01 / SPCC Cold Rolled Steel Coil
DC01 / SPCC Cold Rolled Steel Coil
The right cold rolled steel coil should match your forming process, dimensional requirements and surface specifications. Our DC01 / SPCC cold rolled steel coils are intended for general metalworking applications, including stamping, bending, roll forming and sheet metal fabrication.
We supply steel coils, sheets and strips for industrial manufacturing and metal processing. By defining the grade, thickness, width, coil weight and surface condition, buyers can specify material that fits their production requirements and purchasing standards.
01 Product Overview
DC01 and SPCC are commonly specified grades for cold rolled steel coil, but they belong to different standards:
- DC01 is specified under EN 10130 for cold rolled flat products for cold forming.
- SPCC is specified under JIS G 3141 for cold rolled carbon steel sheet and strip.
These grades should be selected according to the standard required by the buyer. They are not automatically interchangeable, and grade substitution should be confirmed against the required material specification.
Cold rolled steel coil is used in manufacturing where surface condition and dimensional requirements are important. Typical applications include:
- Stamped and bent sheet metal parts
- Electrical cabinets and equipment enclosures
- Appliance panels and components
- Roll-formed profiles and fabricated sections
- Metal furniture and industrial components
- Tubular and other fabricated steel products
The appropriate grade and coil specification depend on the forming operation, component design and downstream surface treatment.
02 Product Specifications & Grade Selection
Grade and Standard
| Item | DC01 | SPCC |
|---|---|---|
| Applicable standard | EN 10130 | JIS G 3141 |
| Material type | Cold rolled low-carbon steel for cold forming | Cold rolled carbon steel sheet and strip |
| Typical processing | Bending, stamping and general cold forming | Bending, stamping and sheet metal fabrication |
| Chemical requirements | According to the applicable EN 10130 requirements | According to the applicable JIS G 3141 requirements |
| Mechanical requirements | According to grade, thickness and delivery condition | According to grade, thickness and delivery condition |
Choose the grade according to the standard specified in your drawing, purchase order or material requirement. Where a project specifies a particular standard, the corresponding grade and inspection documents should be used for acceptance.
DC01 Reference Chemical Composition
The following values are reference limits for DC01. Final material acceptance should follow the applicable standard edition and the chemical analysis recorded on the material test certificate.
| Element | Reference limit |
|---|---|
| Carbon (C) | ≤ 0.12% |
| Manganese (Mn) | ≤ 0.60% |
| Phosphorus (P) | ≤ 0.045% |
| Sulfur (S) | ≤ 0.045% |
Mechanical properties should be checked against the applicable grade, thickness and delivery condition. Specific values should be taken from the relevant standard and the material documentation for the supplied coil.
Coil Dimensions and Order Specifications
| Specification | Selection basis |
|---|---|
| Thickness | According to the required component design and order specification |
| Thickness tolerance | Applicable standard or agreed purchase specification |
| Width | According to the required part dimensions and processing line |
| Width tolerance | Applicable standard or agreed purchase specification |
| Inner diameter (ID) | 508 mm and 610 mm are common industry configurations |
| Outer diameter (OD) | Define according to coil configuration and handling requirements |
| Coil weight | Define according to uncoiling equipment, transport and production needs |
| Edge condition | Mill edge or trimmed edge, subject to order confirmation |
| Surface finish and roughness | Specify according to forming and downstream treatment requirements |
| Surface protection | State whether an oiled or dry surface is required |
| Delivery condition | Specify according to the selected grade and purchase requirements |
The 508 mm and 610 mm inner diameters are common industry configurations, not a statement of a fixed supply range. The selected coil ID should match the buyer's uncoiling equipment. Thickness, width, tolerances, coil weight and other dimensions should be confirmed in the order specification.
03 Surface Condition & Processing Applications
The forming process and finished component determine which cold rolled steel specification is suitable.
Stamping and bending
For stamped or bent parts, consider material thickness, forming depth, bend geometry and the mechanical properties required by the component. DC01 is commonly selected for general cold-forming work. Where a component requires more demanding drawing performance, the buyer should specify the required forming grade rather than assume that DC01 is suitable for every drawing operation.
Roll forming and sheet metal fabrication
For roll-formed profiles, cabinets, enclosures and fabricated components, match the coil width, thickness, edge condition and coil weight to the processing line and finished dimensions.
Surface requirements
Specify the required surface finish and roughness according to the intended application and subsequent treatment, such as painting, coating or welding. State whether an oiled or dry surface is required when submitting the inquiry.
04 Customization & Supply Specifications
For a clear quotation and order review, define the required supply specification across the following items:
- Grade and standard: DC01 / EN 10130 or SPCC / JIS G 3141.
- Thickness and width: Required nominal dimensions and applicable tolerances.
- Coil weight and dimensions: Target coil weight, inner diameter and outer diameter requirements.
- Edge condition: Mill edge or trimmed edge, subject to order confirmation.
- Surface condition: Required finish, roughness and oiled or dry condition.
- Processing requirements: Slitting or other size processing, subject to confirmation of processing availability.
- Packaging requirements: Protection, strapping, edge protection and transport securing instructions.
Please include the intended application and processing method when the material will be used for stamping, bending or roll forming. This helps align the requested grade and coil specification with the actual production requirements.

06 FAQ & RFQ
Are DC01 and SPCC the same grade?
No. DC01 is specified under EN 10130, while SPCC is specified under JIS G 3141. They are different standard designations and should not be treated as automatically interchangeable. Select the grade required by the project specification.
Is DC01 cold rolled steel coil suitable for stamping and bending?
DC01 is commonly used for general cold-forming operations, including bending and stamping. Suitability for a specific component depends on thickness, forming depth, bend geometry and the required material properties. More demanding drawing operations may require a different grade.
What inner diameters are commonly used for cold rolled steel coils?
508 mm and 610 mm are common industry inner-diameter configurations. The required ID should be selected to match the buyer's uncoiling equipment and confirmed in the order specification.
Can thickness and width be specified according to our production requirements?
Thickness and width should be stated in the inquiry together with the required tolerances. The order dimensions and supply range need to be confirmed during quotation.
Can we specify an oiled or dry surface and a particular edge condition?
Yes, these should be identified as order requirements. State the required surface condition and whether mill edge or trimmed edge is needed so that the requested specification can be reviewed before order confirmation.
What information is needed for a quotation?
Please provide the grade and standard, thickness, width, quantity, destination port and intended application. Also include the required coil weight, inner diameter, edge condition, surface condition, packaging instructions and any material inspection-document requirements.
