Bright Finish

305 & 310

305 and 310 are decorative rolled surfaces which are characterized by a bright finish. Their smooth and very homogeneous surface appearance without streaks meets the highest demands of surface quality in the untreated state or with a transparent coat of paint. 305 and 310 are mainly used for emblems, door sill panels, and other trim parts.


Rolled Bright 430 is a decorative rolled surface which is characterized by a brilliant surface appearance with a ground finish visible in the subsurface. 430 is mainly used for the exterior window trim and for a number of decorative interior parts.

Matte Finish

615 & 631
615 and 631 are decorative rolled surfaces which are characterized by a fine, matte structured surface.

They are particularly used for interior parts. They can be further lacquered, brushed and embossed.

Structures Finish

Butler finish 824 & 827 and Longline finish 815
These three finishes are decorative rolled surfaces characterized by a longitudinal surface structure, similar to a brushed surface with a fine discontinuous line structure.

They are used for interior parts.
