A new, elegant, functional definition of concrete.Polished concrete effect floor tiles: the ideal material for a high-tech interior design style. An understated, minimal look to enhance modern architecture, with a subtle touch of class. The distinctive feature of the surface is the used effect typical of worn cement, created thanks to the slightly shimmering metallic reflection. The Metropolis collection by Rondine lends itself to a wide variety of uses, giving a personal touch to public places and to every room of the house. This series of concrete effect tiles, one of the high points in the technological development of porcelain stoneware, comes in 4 coloured body versions three shades of grey and one of ivory and in two sizes (60.5x60.5 and 30.5x60.5 and the rectified 60x60 and 30x60 versions).
