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

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.
