Surface treatment

We anodise and passivate both large and small batches in one of the sector’s most modern, high-tech surface treatment plants. Anodisation is when the aluminium surface is converted through electrolytic oxidation to produce a durable, decorative and corrosion resistant surface. Three chemical methods are used for the passivation process, the trivalent chromium (translucent), the hexavalent chromium (yellow), and the chromium free alternative ECLPS (translucent). The result is good corrosion resistance and a better base for coating.
