Will blue anodized aluminium make your project look better? Then you’re at the right place at Alumet. We’re experts in anodizing and offer a lot of different colour possibilities. The colours aren’t applied as a layer, but are fully integrated with the aluminium.

How do we do it

At Alumet whe have a very modern and specialized machine park. Here we can anodize, colour, brush, polish and grind aluminium in no time. For colouring anodized aluminium, for example blue, we use a electrochemical process to make the top layer into an decorative, wear-resistant, sustainable and corrosion-resistant oxide layer. To give the anodized aluminium the blue colour Alumet uses metal salts. They are deposited in the pores and modified electrochemically. Blue anodized aluminium is 100% UV resistant and will remain beautiful for a long time.

At Alumet you can choose glossy blue anodized alumium, or matt. The choice is yours!

Alumet anodises aluminium in colour and gloss

Our colour range includes 1 blue tone. We do not use pigments, but metals to obtain the blue colour. By depositing metals in the pores and then electrochemically modify the pores (interference anodising), we can obtain the colour dark blue. Blue anodising is 100% UV resistant and will remain sparkling for a long time.

Anodised aluminium used in architecture requires very little maintenance. The anodising layer consists of metal, aluminium oxide and is hard and robust. Maintenance is therefore understood to mean: cleaning of the product. A clean anodised aluminium surface has a very long lifespan. Under normal conditions, it can easily last 80 years, without losing its gloss or colour (e.g. the electrolytically dyed layers).

Cleaning instructions

20 Or 40 year guarantee

Alumet B.V. hereby declares that the anodising activities that it has performed meet the QUALANOD requirements, class 20 mu or 25 mu, which Alumet B.V. and the client had agreed upon in writing. This means that the anodised components will be free of any corrosion and will not contain any cracks, blisters or filiform corrosion. Corrosion on the unprotected and untreated cut will not affect the adjacent anodising layers. The natural and electrolytically coloured components will also not be subject to any discolouration when exposed to sunlight.
