Porcelain tile is a ceramic product made of a homogeneous blend where the surface is not glazed. Heated until vitrification occurs, it is made of clays with silica and feldspar additives. The result is a ceramic product with exceptional qualitative qualities: maximum toughness, resistant to shocks and abrasions, acid resistant, frost proof and characterized by low water absorption. PETRAL offers different series of porcelain tile finishes 600x600: GRES FLOW, PLANET, EXPLORER,  EVOQUE, AMBIENTI , TRIBECA.
