The proximity to the most important Italian espresso coffee machines producers and the long relationships with renewed international brands of sanitary faucet’s producers allowed Rubinetteria GST to have a deep experience about ecological Non Ferrous Alloys with low or zero Lead content. More than 10% of the production is dedicated to the Silicon Cu-Si ECObrass®/CuPHIN® (CW724R) necessary to comply the more strict American standards (Pb<0.2% on the part in contact with sanitary water) and European standard (10 mg/l di Pb). The ability in supply customers in different industrial sectors gave to GST the possibility to use and machine a very large range of Cu-Zn alloys.
For about two years GST realizes Aluminum components, especially in the automotive sector with 6000 series alloys.
