Introduced in 2006, guarantees high corrosion resistance of all Vitillo products in compliance with regulations: RoHS 2002/95/CEEL V 2000/53/CE Vitillo guarantees protection of the environment thanks to the exclusion of hexavalent chromium, maintaining and increasing the corrosion resistance of its products.

The new zinc-plating system, besides ensuring a better rust resistance, improves lubrication and threads coupling.

The new system guarantees a 10-15 micron thickness, and a protection of at least 240 hours in salty mist (ISO 9227) before any appearance of white corrosion.
