Choosing the right surface treatment Sometimes it
can be hard to choose the right surface treatment, depending on the function and location of the part. A few points should therefore be classified with your quality and production departments, in liaison with your sales person: - Type of assembly: manual or automatic - Corrosion resistance: how many hours? - Environment in which the assembly is located: saline or polluted atmosphere? - Colours: Will the part be visible? What colours are available? Finishes for metal parts There are two solutions for protecting parts from corrosion: lamellar galvanizing and electrolytic galvanizing. The table below indicates the corrosion resistance of the different finishes available. Salt spray resistance is given in hours of exposure to white rust or red rust. You’ll find the surface treatments available for all of the references on the materials flap on the catalog cover page. We have many other finishes available, please contact us for more details.

Most of our parts come in 4 colours: white, natural, black and grey. But other colours may be produced as well: brown, green, blue, etc. Please contact us.
