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 coloured layers).

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.


BS3987 is the British Standard for color (where applicable), film thickness, sealing and damage for clear and colored anodizing layers. Alumet is affiliated with BSI.
