Mutina Stoneware doors are built with a powder-coated aluminium frame with a honeycomb matte finish in the back with an ash grey HPL panel and a stoneware/decorative front that is 3 mm thick. Porcelain stoneware is a particular type of ceramic that contains kaolin (the main ingredient of porcelain) and has a very compact and homogeneous structure with a high surface impermeability. Non-porous, does not absorb or emit substances. Stain and scratch resistant, easy to clean.
