Our procedures

What allows us to guarantee the best quality and high standard at any stage is a great experience gained through the years and the avant-garde equipment available.

Standard electrolytic zinc plating

Zinc has an excellent protective power against iron. The protection is electrochemical in nature, since zinc is more electronegative than iron. In the atmospheric agents a galvanic pile is established in which the zinc behaves as an anode.

Galvanizing with high corrosion resistance

First step is a galvanizing process, with a thickness between 5 and 20 microns, which is subsequently protected by chromate with a high content of trivalent chromium, in order to give the deposit an iridescent color.

Innovative zinkel® (zinc-nickel) treatment

The Zinc Nickel is the most widespread process in the electrolytic deposition of zinc alloys. This treatment was conceived to meet the very high protection demand required by the automotive market.

Galvanizing and zinkel® on cast iron

The cast iron (also called, until the nineteenth century, 'ferraccio' [bad iron] for the lower quality and the worst workability compared to mild steel) is a relatively high carbon alloy (2.11%

Zinc Nickel duplex frame

We installed a new system "duplex" frame with dedicated line to Zinc Nickel. Today, therefore, we can offer our customers not only the Zinkel® treatment with zinc-nickel acid, but also with alkaline zinc-nickel, so as to satisfy the automotive department.

Why metal treatment is so important

Protecting materials from the wear is our job. Why is it so important? Full functionality and integrity of each component means producing with high standards,
and recreate production excellence.

In an increasingly global and competitive world, which is changing ever faster, excellence is the only guarantee to keep up with the times and
ensure a future for a company.
