CUPA PIZARRAS’ TRACEABILITY | ASSURANCE

CUPA PIZARRAS has a unique comprehensive quality control system that enables us to identify the origin, type, technical data and production dates for each of our natural slates. Our traceability procedure is implemented using a unique bar code that accompanies the slate throughout the production process.

This system enables us to monitor the quality of all our products in real time, but, more importantly, it makes it possible to provide our distributors and customers with precise information on each slate produced.

This traceability system allows true monitoring from the quarry to the end consumer, guaranteeing our differentiating value – quality.

OPTING FOR PEACE OF MIND | CHOOSE CUPA PIZARRAS

A good quality natural slate is an unbeatable product for any project, thanks to its natural properties. However, there are products on the market that vary in composition and quality, giving highly diverse performance.

It is essential to demand specific information from the producer on the natural slate chosen for your product.

Any slate production needs to be accompanied by at least:

As a general rule, we at CUPA PIZARRAS always recommend acquiring natural slate with producer company brand and information, avoiding generic and distributor’s brands as far as possible as these make it difficult to correctly identify the product.

Unlike other brands, CUPA PIZARRAS produces and transforms its natural slate in its own quarries and units, enabling us to control product quality from source.
