Slate Stones

The name slate is due to the characteristic property of the rock to be torn into thin sheets in a direction perpendicular to its compression direction.Slate is a natural rock formed millions of years ago, easily cracked into slabs, and delivered in irregular natural dimensions. Irregular slate stones are the most commonly used stones for flooring outdoors such as in backyards, in the garden as paths, on balconies, in cottages, in fencing, in business premises, in fireplaces, barbeque, exterior wall cladding on the outside of the House. Also install wall cladding inside the houses, giving the natural look of stone to our decoration. It can be placed anywhere else we want to add to the beauty of natural stone. Depending on the order, the slate slabs are divided into colors and thicknesses ranging from 1.3 to 2.5 cm and from 3 to 5 cm. In other cases the plates remain in an irregular shape while in others they are cut into rectangles-squares.
