Cupa Natural Slate
CUPA Natural Slates are supplied by the world’s principal slate producer, marketing more than a quarter of the world’s slate per annum. Cupa has a system of traceability ensuring that the company is able to identify and provide information about the origin and the production history of each consignment of slate. For CUPA to be able to offer such a guarantee has meant the implementation of a very thorough quality control system that safeguards all aspects of their production process.
Slate bearing the CUPA trademark is extracted from over fifteen quarries, which are located in the provinces of Orense, Lugo, Leon and Zamora.
