Zinc plating

Zn & Zn/Ni

We use zinc electroplating to add a zinc coat to materials (Zn and Zn/Ni), which serves as a base layer for further coating, or as a surface finish it gives products a more attractive appearance than in their unfinished state. In any case it fundamentally improves the mechanical and electrical properties of metals.

Advantages of zinc electroplating

  • improves the mechanical and electrical properties of metal
  • even a thin layer ensures great resistance to corrosion and other environmental influences
  • low economic costs
  • serves as a primer or final surface treatment
  • environmentally friendly technology of chromate coating without hexavalent Cr

Key properties of galvanisation with Lakum

  • rack and mass zinc electroplating
  • zinc plating of even large parts is possible
  • we ensure various degrees of corrosion resistance
  • combined with subsequent surface finishes we make your products “immortal”
  • we also offer blue and thick-layer passivation (chromate coating) and surface sealing with silicate paint

Anticorrosion according to your requirements

The galvanisation process is completely automated, but it can be modified in the individual phases. As a result, the individual galvanisation phases can be tailored to your requirements for the resultant quality and appearance of the products, and different levels of corrosion resistance can be achieved.

We protect small and large parts

Galvanisation is primarily suitable as a surface finish for metal parts, connection elements, anchoring elements, castings or forgings. So called passivation (chromate coating) or sealing using silicate paint may also be part of the galvanisation surface finish process.
