Granite, slate and trachyte


Beside its company-own quarry stones, Grassi Pietre offers a selection of granites and slate, to offer its clients compact materials for specific need ( i.e. outside flooring in cold areas..).


Grassi Pietre can provide different kinds of slates, both Italian and imported.


The trachyte is a volcanic rock with a color from gray to yellow / brown. It is a material suitable for use even in exterior for its characteristics of resistance to wear.
