Our technicians’ experience is at the disposal of our client base in the sustained search for improvement in both the choice of materials for melting recipes and for the application modalities. A sustained presence in the market over a number of decades, allows us to count on an ample choice of alloys of our formulation in our production range, responding to precise in-house qualitative specifications, apart from a considerable number of standardised alloys as well. The prerogative of our productions is the absolute observance of qualitative standards, whether these are required by national, Italian or foreign unifications (UNI -DIN -BS – ASTM – AFNOR -ISO etc.) or should these be imposed by client specifications. Our control laboratories systematically provide their support with advanced equipment and methods aimed at verifying compliance at every stage of the productive cycle. Furthermore, at the utilisation stage, our technical assistance facilities are available on request at client premises, providing advice and collaborating in finding solutions to problems of an operative nature.
