Traitements de surface

In recent years, we have developed a large international network of specialised suppliers of surface treatments. This allows us to offer your surface treatment from the best parties for competitive rates. In this manner, CIREX can unburden you completely in the area of surface treatments, and your products are delivered ready to be built in.

A surface treatment or coating is a treatment in which an upper layer is applied on a substrate. There are multiple purposes for surface treatments:

  • Improving appearance
  • Improving surface properties
  • Protecting the surface from damaging external influences (corrosion or wear)

For steel components, the surface treatments can be achieved with a galvanic, chemical or mechanical treatment. Since material is transposed in this process, it is sometimes also called building up a conversion layer. So whether a smaller or larger series of castings must be given surface treatment, we can provide you with advice.
