Surface finishes
All steel grades are available with surface finishes A and B (EN 10130) and 03 and 05 (DIN 1623) respectively, with the following reservations:
- The mild and the isotropic steel grades can only be supplied by agreement with surface finish B and 05 respectively in widths > 1.700 mm.
- Structural steel and micro-alloyed steel grades with higher yield points can only be supplied with surface finish A and 03 respectively.

Surface finish
The following sorts of lubricant are available:
- Prelub oil – drain resistant lubricant
- Corrosion protection lubricant
- Hotmelt – dry film lubricant
| Surface treatment | Code |
| Phosphated | P |
| Phosphated and passivated | PC* |
| Phosphated, passivated and oiled | PC*O |
| Phosphated and oiled | PO |
| Oiled | O |
| No finish treatment | U |
*C
Standard is a passivation free from chromium, wich is only available in combination with a phosphatization. A passivation without phosphatization is not possible.
A chemical passivation is only technical feasible on material which is electro-zinc coated on both sides.
