Special hot processed types
We always use the most suitable raw materials
for each specific production process, therefore we purchase
from foreign markets as well as the Italian market
This is the reason why we are able to certify the quality
of the materials and the various production stages we employ.
The final tests we carry out on our products guarantee that
they correspond exactly to customer requirements (UNI-DIN
standards).
