A newer Barrel Line can deliver either Zinc Nickel, Tin Zinc or Zinc Iron plating.

With a throughput capacity of 5 tonnes per day, it is designed to handle smaller parts such as fasteners and rivets.

As is the case with the rack plating Zinc Nickel line, the benefits of this process include the high ductility, corrosion immunity, hardness and heat resistance of the plating. It is an alternative to Cadmium plating and is compatible with Chrome 6 FREE passivates.

The benefits offered by Tin Zinc plating include the fact that the finished surface has high resistance to corrosion. It possesses excellent ductility, and can maintain its integrity even under severe bending and crimping. Even after being aged for several months its good solderability characteristics are retained.

Tin Zinc plating provides good corrosion protection to the steel at steel/ aluminium interfaces. Its electrical conductivity is high. Because the plating process is neutral it may be applied to electronic components and to glass-to-metal seals with no risk of attack to the glass. It is also an alternative process to Cadmium plating.
