Perforated anodised aluminium sheets are used more and more - for aesthetic, architectural or technical reasons. The untreated raw aluminium surface is very sensitive and susceptible to corrosion from atmospheric conditions. Untreated aluminium becomes dull and grey in time, whereas an anodised surface will keep its looks for many years – practically without maintenance.
When required, RMIG can arrange the anodising of your perforated sheets in natural or coloured finishes.
Advantages of anodising
- Improved corrosion resistance
- Superb colour stability
- Low fingerprint sensitivity
- Scratch resistance for high value products
- Possibility for a different decorative surface, e.g. by colouring
For indoor use we generally recommend an anodising of minimum 10 micrometres (10 mµ) on one side, and for outdoor use we generally recommend an anodising of minimum 20 micrometres (20 mµ) on one side (the side visible).
