Slate

Slate is a natural rock with a lamellar structure and a dark grey to black colour. Valli Granulati washes, dries and screens it in several grain sizes, from decorative flakes to powder.

The range includes 30/60 mm flakes for decorating and mulching gardens and flower beds, granules for the self-protection of bituminous membranes, powder (filler) and coloured slate, coated with epoxy polymer and iron oxides.
