Dark grey slate with thin laminations and a smooth surface. Split to an average thickness of 3,5 mm, 5 mm and 6 mm.
This is an extraordinary rigorous classification process in which only pieces with high flatness and the very regular thickness could pass. This is considered to be the best natural slate produced in the world. Moreover, it is ideal for projects where a homogenous result for a perfect roof is demanded.
