Cold rolled steel is also part of our product portfolio. Cold rolled steel is excellent for cold forming. This product group assigned the grades DC01 to DC07, DC01EK to DC06EK, DC03ED to DC06ED and S215G to S325G.

The grades are classified according to the maximum permissible yield strength and can be subdivided as follows.
DC01 – This grade can be used for simple forming work, for example Bending, embossing, beading and pulling are used.
DC03 – This grade is suitable for forming requirements such as Deep drawing and difficult profiles suitable.
DC04 – This quality is suitable for high deformation requirements.
DC05 – This thermoforming grade is suitable for higher forming requirements.
DC06 – This special deep drawing quality is suitable for the highest deformation requirements.
DC07 – This super deep drawing quality is suitable for extreme deformation requirements.

Enamelled grades
The steel grades DC01EK, DC04EK and DC06EK are suitable for conventional single-layer or double-layer enamelling.

The steel grades DC06ED, DE04ED and DC06ED are suitable for direct enamelling as well as for enamelling according to the two-layer / one-firing method and for special applications of two-layer enamelling for low-distortion enamelling.

Surface type

Surface A
Mistakes such as pores, small grooves, small warts, slight scratches and a slight discoloration that does not affect the ability to reshape and adhere to surface coatings are permitted.

Surface B
The better side must be free from defects so that the homogeneous appearance of a quality finish or an electrolytically applied coating is not impaired. The other side must at least meet the requirements of surface type A.

Surface finish
The surface finish may be particularly smooth, dull or rough. If no details are given when ordering, the surface finish will be delivered in a matt finish. The four surface finishes listed correspond to the center roughness values in the following table and must be tested in accordance with EN 10049.
Surface finish characteristic Average surface finish
(boundary value: 0,8mm)
Special flat b Ra ≤ 0,4 µm
flat g Ra ≤ 0,9 µm
Matt m 0,60 µm ˂ Ra ≤ 1,9 µm
rough r Ra ≤ 1,6 µm
