Zinc plating

Why zinc coatings?

The biggest consumer of steel in the world is rust!

Your workpieces can be sufficiently protected against corrosion thanks to zinc plating, which applies zinc layers of between 5 and 30 µm thickness, depending on requirements.

The advantages of zinc plating:

Functional and decorative
High cathodic corrosion protection
Economical
With chromate conversion coatings (containing CrVI) in yellow, olive and black
With passivation (CrVI-free) in blue or transparent and as thin-film and thick-film passivation
Optionally with sealers
High ductility – subsequently workable if the layer is suitably thick
With the right after-treatment, high resistance to zinc corrosion (white rust)

Which after-treatment?

The correct after-treatments first of all play a decisive role in the appearance of your zinc-plated workpieces and their resistance to white rust. They, in conjunction with a suitable thickness of zinc plating, ultimately result in the high level of protection against red rust. With the appropriate after-treatment, it is also possible to achieve decorative layers, e.g. silver-coloured (transparent) or black, as well as functional layers, such as ones with defined coefficients of friction.
