Precision Steel Sheets for High-Quality Applications
Cold Rolled Coils (CRC) are steel sheets processed by rolling at room temperature to achieve precise thickness, smooth surface finish, and improved mechanical properties. CRC is widely used in industries that demand high-quality steel with tight tolerances and excellent formability.
Key Characteristics of Cold Rolled Coils
Smooth Surface Finish
Cold rolling produces a smooth, clean surface ideal for painting, plating, and further finishing processes.
Tight Thickness Tolerances
CRC offers better dimensional accuracy compared to hot rolled steel, making it suitable for precision applications.
Improved Mechanical Properties
Cold rolling increases yield and tensile strength while maintaining good ductility, allowing easier bending and forming.
Available in Various Grades
Common grades include:
- DC01 / DC03 / DC04 – Common cold rolled steels for general fabrication.
- SPCC – Cold rolled carbon steel for automotive and appliance industries.
- HX340LAD / HX420LAD – High-strength cold rolled steels for structural use.
Standard Thickness and Width
Typically supplied in thicknesses from 0.2 mm to 3.0 mm and widths from 600 mm to 1500 mm, in coils of varying weights.
Common Applications of Cold Rolled Coils
Automotive Industry
Used for body panels, chassis components, and decorative trim.
Appliance Manufacturing
Ideal for refrigerators, washing machines, and other home appliances requiring smooth finishes.
Furniture and Fixtures
Applied in metal furniture parts and office equipment.
Electrical and Electronic Products
Used in cases, enclosures, and components needing precise dimensions.
Metal Stamping and Fabrication
Preferred for high-precision stamping and forming applications.
Typical CRC Specifications
| Thickness (mm) | Width (mm) | Coil Weight (tons) |
|---|---|---|
| 0.3 – 3.0 | 600 – 1500 | 3 – 25 |
Why Choose Cold Rolled Coils
CRC provides superior surface quality and mechanical properties for demanding applications. Their precision and versatility make them essential in automotive, appliance, and electronics manufacturing.
