All coatings may look similar at first glance, but there are many factors that will influence the lifespan of a good or bad surface finish over time. Surface quality is directly dependent on surface treatment, film thickness, process control and proved specified standards.

Surface finishing is mostly used to improve the appearance and extend the lifespan of aluminium extrusions. Furthermore, it is common for aluminium profiles to be anodised after surface finishing has been applied.

For some industries, the surface’s aesthetics is one of the most crucial  elements. Hence, Emerus provides surface treatments adapted to our  customers’ requests.


Anodising is an electrochemical process that thickens and toughens the naturally occurring protective oxide layer in aluminium. Anodising successfully combines science with nature to create one of the world’s best metal finishes that is also environmentally safe. The resulting finish, depending on the process, is one of the hardest substances known to man.
The anodic coating is part of the metal, but has a porous structure that allows secondary infusions (organic and inorganic colouring, etc.) Anodising is commercially unique to aluminium and its alloys.

Main reasons for usage of anodic coating:

– decoration, through a variety of colors
– a long-lasting appearance
– protection against weathering
– surface hardness
– abrasion and wear resistance
– reduction of friction and improvement of water repellency
– improvement of adhesion of organic coatings (adhesives, varnish, paint)
– modification of electrical properties (insulation)
– modification of visual properties (reflectivity)

Among many surface finishing options for aluminium extrusion products,  powder coating is the most favoured, durable, and cost-effective alter native. This method makes surfaces long-lasting and functional while also  producing a decorative appearance.
