Cut to size

Our vertical production gives us the opportunity to have full quality control during the whole process, in order to achieve the best result and satisfy the needs of the most demanding customer.

Our factory is fully equipped with all the machinery needed, from gang saws and monowires to bridge saws, edge polishers and line polishing machines.

We constantly keep you informed of every step of the project from the very beginning up to the final packing of your order, making sure that the final product will have passed through all the needed quality controls.

Additionally, we have invested in our after-sales support, by providing to the wholesaler or the engineering office any assistance related to the treating of the marble, in case a minor or important renovation is needed after many years. We have the knowledge to suggest the best products and techniques for the protection or removal of any marks.

In order to offer the highest standard of services to our customers, both in the private and the public sector, and for them to feel confident about our company, we have received from the state the FPC (Factory Production Control) accreditation.

This accreditation ensures that our company has a permanent internal control of the whole production process, following specific steps and procedures. Not to mention that all materials and processing techniques adopted by our company are documented in a systematic manner.

Our management permanently monitors the procedures and double-checks the Production Manager, in order to ensure the effectiveness of the FPC system. In addition, it continuously verifies that all the personnel adhere to the requested procedures, ensuring compliance with the system.

The main objective of the company is to ensure the perfection of its’ production, from the processing of the blocks to the delivery of the final cut-to-size product.

We are able to ensure:

  • that the production process is in accordance with the required standards
  • our ability to identify potentially defective products
  • that all the materials are stored in the appropriate conditions
  • that the materials sold from stock are not altered from their production
  • the tracing of our product after it has arrived in the market

We keep full records of our produced goods, during all the steps of the production and our FPC system keeps track of all matters related to marking, storage, packaging and delivery of the goods.

Our main intention is to offer excellent production services and after-sales support to our customers, always in respect with the environmental rules of production.
