These aluminium-blank sheets are special friction (butler-finish) and to anodized blank sheets (in the condition of H 12), with a specially surface quality. This quality is corresponding with the bevelled (grain 180) surface of high-steel in the decoratively. The blank sheets are onesided supplied with protective foil.
