Slate is a fine-grained, foliated metamorphic rock that is created by the alteration of shale or mudstone by low-grade regional metamorphism. Slate Stone Tiles can be installed like any ceramic tiles. These tiles are used for various purposes and wherever they are installed, be it the roof, floor, walls, outdoors or indoors.
