HGT Galestro gres porcelain vitrified stoneware, available in 15x15, 15x30, 15x45, 30x30 e 30x45, is the result of a research programme that permitted the creation of products in which the excellent characteristics of high-grade vitrified stoneware (resistance to freezing, chemical agents, slipping and breakage) are combined with an exceptional level of aesthetic appeal, rarely found previously in such distinctly technical products.
