Flat products for silverware

Our flat products are designed for the manufacture of giftware and silver tableware. They are the result of specific research, which involved the setting up of a process flowchart that has allowed us to obtain a finished product of high consistent quality. They can used to produce items requiring sophisticated processes, including deep drawing, and an absolutely defect-free surface finish.
