About Adriano Bignasca SA
Adriano Bignasca SA is a long-established Swiss company from Lodrino in Ticino, specialising in the extraction and processing of Ticino gneiss. The company operates its own quarries in Iragna and Personico, from which the rock blocks are extracted directly.

The product range includes customised solutions made from high-quality granite and natural stone for road construction and urban street furniture, outdoor and indoor flooring, garden fittings, masonry works and superstructure elements. Customers include both businesses and private individuals. According to its own statement, the company combines 129 years of experience and craftsmanship tradition with modern processing methods and offers expert advice as well as solutions tailored to the requirements of each project.
