Cold Rolled Steel Grades

We offer a comprehensive range of cold-rolled steel grades, including common grades that meet both JIS (Japanese Industrial Standards) and EN (European Norm) specifications. Our products cover everything from commercial-grade steel to deep-drawing quality steel, meeting the demanding requirements of our clients for material ductility and formability.

Japanese JIS standard grade

  • Known for its general-purpose applications, it is suitable for simple forming and bending.
  • Low-carbon cold-rolled steel with moderate strength and a smooth surface.
  • Mainly used for general stampings, appliance panels, and lightweight structural parts.
SPCC Cold Rolled Steel Coil

Japanese JIS standard grade

  • Low-carbon cold-rolled steel with slightly higher strength than SPCC
  • Good ductility, suitable for deep drawing
  • Commonly used for automotive parts and thin sheet components
SPCD Cold Rolled Steel Coil

Japanese JIS standard grade

  • Ultra-low carbon cold-rolled steel with excellent ductility
  • Suitable for deep drawing and complex forming
  • Commonly used in automotive structural parts and complex home appliance panels
SPCE Cold Rolled Steel Coil

European EN standard grade

  • General-purpose low-carbon cold-rolled steel with a smooth surface.
  • Suitable for stamping, bending, and coating.
  • Widely used in the automotive, appliance, and construction industries.
DC01 Cold Rolled Steel Coil

European EN standard grades

  • Low-carbon cold-rolled steel with a better balance of strength and ductility than DC01.
  • Suitable for general stampings and lightweight structural parts.
  • Commonly used in home appliance panels, mechanical parts, etc.
DC03 Cold Rolled Steel Coil

European EN standard grades

  • Ultra-low carbon cold-rolled steel with excellent ductility
  • Suitable for deep drawing, complex forming, and high-precision parts
  • Widely used in automotive bodies and high-end home appliance parts
DC06 Cold Rolled Steel Coil

Advantages of Cold Rolled Steel

Cold-rolled steel is produced by reprocessing hot-rolled steel sheets by rolling them below their recrystallization temperature. This process gives cold-rolled steel its unique properties, making it highly sought after in many industrial sectors.
High strength and hardness

High strength and hardness

Cold-rolled steel, thanks to its unique processing, possesses remarkably high strength and hardness. This property allows it to withstand high stresses and pressures with exceptional performance and resists deformation. Furthermore, cold-rolled steel offers excellent wear resistance, extending component life and reducing the need for replacement and maintenance.
Plasticity and precision

Plasticity and precision

Cold-rolled steel offers excellent plasticity and exceptional precision. The cold rolling process refines the steel's grain structure, making it amenable to further processing such as stamping, bending, and forming. Furthermore, cold-rolled steel offers tight dimensional tolerances and a high degree of surface flatness, enabling it to meet the highest precision demands in manufacturing applications.
Surface quality

Surface quality

Another significant advantage of cold-rolled steel is its surface quality. The cold-rolling process creates a smooth, even surface. This superior surface quality not only enhances the product's aesthetics but also provides an excellent foundation for subsequent surface treatments such as electroplating and painting, reducing pre-treatment costs and time.
Cost-effectiveness

Cost-effectiveness

Cold-rolled steel is more cost-effective than other metal materials in certain applications. While processing costs are relatively high, its excellent mechanical properties, high precision, and superior surface quality reduce the need for subsequent processing steps and scrap, thereby lowering overall manufacturing costs. This makes cold-rolled steel the material of choice for many products requiring high precision and excellent surface quality.
