Cold-rolled steel
What is Cold-rolled steel?
Cold-rolled steel refers to hot-rolled steel that has been processed further at room temperature through precision rolling mills to achieve excellent dimensional accuracy, a smooth surface finish, and improved mechanical strength. This low-temperature processing allows the steel to develop superior surface quality compared to hot-rolled material, making cold-rolled steel the preferred choice for applications requiring clean appearance, tight tolerances, and good forming performance.
Because cold-rolled steel is widely used across industries such as automotive parts, household appliances, metal furniture, electrical enclosures.Understanding grade classifications helps engineers and procurement teams select the right material for forming, stamping, welding, and coating.
Common Cold-Rolled Steel Grades
Cold-rolled steel grades vary by global standard. The most frequently used grades fall under the European EN 10130 standard, Japanese JIS G 3141 standard, and American ASTM A1008 standard.
Table: Common Cold-Rolled Steel Grades
| Standard | Grade | Typical Use | Notes |
|---|---|---|---|
| EN 10130 | DC01 | General forming, bending | Most common cold-rolled steel in Europe |
| DC03 | Drawing | Better formability | |
| DC04 | Deep drawing | Automotive + appliance parts | |
| DC05, DC06, DC07 | Extra/ultra-deep drawing | Highly formable | |
| JIS G 3141 | SPCC | General commercial use | Most common CR sheet in Asia |
| SPCD | Drawing | Higher ductility | |
| SPCE | Deep drawing | Premium surface quality | |
| ASTM A1008 | CS | Commercial Steel | General fabrication |
| DS, DDS | Drawing-quality | Improved elongation | |
| EDDS | Extra deep drawing | High formability |
What Is the Most Common Cold-Rolled Steel Grade?
The answer depends on regional usage:
- Worldwide (overall): SPCC & DC01 are the most widely used
- Europe: DC01 is the most common commercial cold-rolled sheet
- Asia: SPCC is the dominant grade for everyday manufacturing
- North America: ASTM A1008 CS Type A is the standard commercial quality
Among all of these, DC01 and SPCC are globally considered the most common cold-rolled steel grades because they offer:
- Stable mechanical properties
- Suitable ductility for general forming
- Good weldability
- Smooth surface finish
- Wide availability in sheets and coils
These grades fit a broad range of applications, making them the industry's universal choice for cold-rolled steel.
Why DC01 and SPCC Are the Most Common
Cost-Effective
– These grades provide an excellent balance of price and performance.
Versatile
– Suitable for bending, profiling, stamping, and moderate drawing.
Easy to Coat and Paint
– Smooth surfaces make them ideal for powder coating, painting, and plating.
Stable Supply
– Most countries include DC01 or SPCC as their standard base-grade cold-rolled steel.
Applications Where the Most Common Grades Are Used
- Electrical cabinets
- Furniture and office equipment
- Auto body panels
- Home appliance shells
- Metal stamping components
- HVAC systems
- Hardware and fabrication parts
