New trivalent black processing

Elettrogalvanica Bolis S.r.l. has developed the new trivalent black zinc plating, which ensures an aesthetic result very close to that obtained with the previous passivation with hexavalent chromium.

For the health of employees, customers and the environment, we are proud to announce that all pastings made of chromium VI have been eliminated, as a substance potentially harmful to health.
