Brushing is a form of processing that results in a satin finish. This consists of a large number of more or less parallel scratches, which give in the typical satin effect. The satin finish can be achieved in several ways, namely: using metal wire brushes, using brushes with sisal rope, using brushes with hair and brush paste and using non-woven nylon, Scotch Brite®.

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).

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.

For multiple purposes

Brushing can be used for multiple purposes. For example, it can be used to make small scratches on the aluminium surface to create a stainless steel look. Very light bronze anodizing, combined with brushing creates a color is named Alu-Inox. It can also be used to make a semi glossy surface by using canvas brushes. The effect is a shiny surface with visible brush marks. Extrusion lines are partly removed.
