Moselschiefer® comes from the mines Katzenberg and Margareta and for many centuries it has been a term for top slate quality. Already round about 1850 the original transport route via the Moselle River gave the much sought-after building material its name. The historical choice of name has established itself as a term of quality.
InterSIN® is our international trade mark for slate from the best international deposits. When selecting the exploitation sites we orientate ourselves to the high quality of the Moselschiefer®. The processing quality is checked every day on site.
ColorSIN® is coloured slate in the shades purple, red brown, ruby red, grey-green, dark green, leaf-green, light green and lime-green.
By now this slate is also coming from international deposits since the corresponding national deposits have been exhausted a long time ago.
