The MACO TRICOAT hardware has been designed specifically for uses in which a high level of resistance to corrosion is necessary.  The distinctive trait of the MACO TRICOAT hardware lies in the fact that another organic "Top Coat" layer (cataphoresis + paint) is applied to the surface treated with electrolytic zinc plating to the accessories with a silver finish, already installed, providing the MACO TRICOAT components with a very high level of resistance to chemical aggression and corrosion and making them of a much higher level from a quality point of view compared with the hardware treated with the normal zinc plating procedure.
