In the last few years we have developed many systems that use different nanotechnology products for several metal substrates such as iron, galvanized iron, aluminum.

These innovative treatments are increasingly used in place of phosphate .These treatments confer to the surface of the pieces a conversion very chemically bound and very stable, which increases the corrosion resistance and increases the bonding of the finish.

Depending on the types of production and depending on the desired results nanotechnology can also be engaged in systems where there will be the phosphating stage.
