Mission, vision and values

Granisa has always sought the perfection of the raw material, an excellent personal service and an impeccable service, constantly thinking that the biggest beneficiaries of our work are our customers.

For this reason, we supervise the granite from its extraction in the quarries until its arrival to the final client. We have purchase agreements in the exploitation of quarries throughout the world, which allows us to have a permanent stock of more than 150 types of granite. When the blocks arrive at our factory, an excellent human team treats them with the best machinery and the latest technology to obtain unique and top quality pieces.

Our great respect for the suppliers and the distribution channel makes us faithful and attentive partners, for Granisa the human capital is the basis of all success. The demand of the national and international market also makes us demand more from ourselves and offer a personalized service for each client.

The continuous evolution of the market keeps us alert, always ready to know the latest advances and implement cutting-edge techniques in our own company. Granisa has always tried to go one step ahead, putting the needs of our customers before the commercial interests of our company.
