Quarry tile is a building material, usually 1⁄2 to 3⁄4 inch (13 to 19 mm) thick, made by either the extrusion process or more commonly by press forming and firing natural clay or shales.
Such tiles, given the generally local and non-standardised production, commonly vary between those dimensions, but rarely stray outside of them.
Industrial quarry tile is available with abrasive frit embedded in the surface to provide a non-slip finish in wet areas such as commercial kitchens and laboratories.
Most commercial kitchens require a quarry tile to be used because of its slip resistant and non-porous properties.
Matching trim shapes such as coves, bases, shoes, and bullnoses are available to turn corners and terminate runs of the tile.
