Cold rolled steel is part of our product portfolio. Cold rolled steel is ideally suited for cold forming.
DC01 – This grade can be used for simple forming jobs such as bending, embossing, hemming and stretching.
DC03 – This grade is suitable for forming requirements such as deep drawing and difficult profiles.
DC04 – This quality is suitable for high deformation requirements.
DC05 – This hot forming grade is suitable for higher forming requirements.
DC06 – This special deep drawing quality is suitable for the highest deformation requirements.
DC07 – This extra deep drawing quality is suitable for extreme deformation requirements.
