We are closed for holidays during week 28-31 both in the office and goods reception.

Decorative chrome plating

Chromium is one of the hardest and most abrasion resistant metals. It is also very resistant to corrosion and has a surface that, unlike nickel, retains its luster in an outdoor atmosphere.
We use a unique technology where we apply three different nickel layers to achieve the best possible corrosion protection in combination with a high finish well suited for details that are exposed to a corrosive environment.
Damp and / or polluted air attacks all metals, even nickel, albeit at a much slower rate than e.g. steel. The chrome layer counteracts these attacks while preserving the gloss of the surface and increasing its resistance to mechanical stress. Nickel is anodic in relation to chromium. This means that corrosion – albeit slowly, begins in the nickel layer. The chrome coating can not be made completely tight. This can be counteracted in various ways by making the chrome layer microcracked, approx: 250 cracks / cm in each direction or microporous, approx: 10000 micropores / cm2. This increases the exposed nickel surface relative to the chromium surface, which reduces the rate of attack. Due to the fact that chromium itself is inductive and hard, which often causes cracks in the chromium layer, this alone does not provide good corrosion protection but must be combined with the underlying nickel layer. On the other hand, it is very suitable for preserving the gloss of polished stainless steel. Unlike hard chrome plating, today there are gloss chrome plating processes that are based on trivalent chromium that are not affected by the REACH ban.
