Granite
Gruppo Tosco Marmi works exclusively with natural stones sourced from carefully selected quarries and specializes in materials extracted from the Ossola Valley, such as Serizzo, Beole, and Montorfano White Granite. It also offers stones from nearby Canton Ticino, including Lodrino, Iragna, and Maggia.
Stone belonging to the granite family is highly valued for its physical and mechanical characteristics, its aesthetic qualities and the versatility of uses.
This stone is hard, compact, waterproof, and resistant to fire, ice and other harsh weather conditions.
Granite can be used for interior design and construction. Its uses are veneer walls, interior and exterior flooring, stairways, balconies, windowsills, fireplaces, tables, kitchen countertops, bath vanities and outdoor furniture. In addition, it is perfect for well ventilated exterior façade finishes of prominent buildings and for funerary art.
