A slate is a fine-grained metamorphic rock that splits into thin, smooth-surfaced layers, forming an essential building material used at a large scale in the construction of buildings. Slate tiles and slate stones are suitable for exterior and interior applications such as wall-cladding, roofing, flooring etc. Slate stones are known by many names such as grey slates, flags, flagstones, thick stones, slats, flat stones, stone tiles and tile stones.
