The importance of provenance
We are the only slate producer to carry out the entire manufacturing process in-house, combining traditional craftsmanship with the latest extraction techniques and maintaining total control over quality at every stage.
When you choose a CUPA PIZARRAS slate, you can be certain that the slate you receive is exactly what you have specified. All CUPA slate pallets include a label with a unique barcode that accurately identifies the natural slate inside.
Opting for peace of mind, choose CUPA PIZARRAS
Too often, ‘white label’ slates of unspecified origins can spoil the aesthetic of a project due to their inconsistent performance. By contrast, all pallets of genuine CUPA PIZARRAS slate come with a Certificate of Authenticity and barcoded traceability label that guarantees their provenance and ensures uniform quality and appearance.
The barcode allows to monitor slate quality from start to finish and provide precise information.
