DC01 Cold Rolled Forming Steel

DC01 cold rolled steel is one of the most widely used mild steel grades under the EN 10130 standard. Known for its excellent surface quality, consistent mechanical performance, and superior forming capability, DC01 is a preferred material in automotive manufacturing, household appliances, metal furniture, construction components, and precision-engineered parts.

Surface quality

Surface quality A

Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration.

Surface quality B

The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details.

Inspected side

As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

Surface texture/roughness
Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, GNEE Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

Preservative oil
The standard oil applied by GNEE Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
GNEE Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.Other oiling levels are available on request.

Surface cleanliness
GNEE Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%.
