Slate is not exactly like slate

The Rathscheck Quality System

Rathscheck Schiefer - The Rathscheck Quality System

The Rathscheck Quality System exceeds by far the required national and European test standards and is based on many decades of experience in the production of slate for roof and façade. These resulted in a test system for assessing the worldwide slate qualities. Only the best slate deposits comply with our strict requirements.

With test methods developed by ourselves, by constantly checking our own production processes on site as well as the productions of our international strategic partner we take care of the observance of the Rathscheck quality criteria. At the same time we are supported by independent test institutions.
