Surface treatment from Sapa
Even good ideas can be improved
The particularly high quality and the appearance of extruded aluminium profiles are completely satisfactory for many applications so that additional finishing is unnecessary.
Even so, there are good reasons for subjecting profiles to surface treatment. It allows the following properties of the aluminium to be modified:
- surface structure
- colour
- corrosion resistance
- hardness
- wear resistance
- reflectivity
- electrical insulation
