In terms of surfaces we go into depth !

Together with our equipased partners we implement almost every surface finishing for your fixing elements. Here you will find the most common ones.

Phosphate Coating

This process is mostly used at steel, in order to enhance the corrosion protection. Layers of hardly soluble phosphates are put on the pickled material. Based on the type we distinguish between iron- zinc- or manganese phosphate coating.  
These phosphate coatings provide a temporary corrosion protection. They are often used as a surface for other coatings, as they care for a good solidity for continuing layers.
