Surfaces can be perceived in different
ways. Things like gloss, colour and structure all contribute towards
creating an impression on the mind of those looking at or even feeling for
the surface. The surface has a great impact on giving the object its
character. Aluminium is an excellent material in various respects. Extruded
aluminium profiles create complex forms with an integrated functionality.
This may be difficult to achieve in any other form. In this section
information is given as to how a extruded aluminium profile can be surface
treated and how different surface treatment techniques are used for creating
different decorative and functional properties. The following cross section
of images takes a look at the different aluminium extruded profiles that are
surface treated for better results.
Although the appearance and quality of the surface, for extruded aluminium
profile remains satisfactory for several types of application. As
aluminium's innate properties makes the extruded profiles develop an
excellent resistance against corrosion. Therefore finishing just for the
sake of corrosion protection is seldom necessary.
Advantages of Surface Finish
Surface finish of the profiles are done for a number of other reasons, that
includes considerations like decorative and functional. Following are just a
few examples of properties that finishing can change:
- Improving Surface structure
- Colour
- Corrosion-resistance
- Hardness
- Durability
- Reflectivity
- Electrical screening ability
Methods to improve Surface finish
There are many methods available these days that can enhance the features
of an extruded profile by enhancing the surface finish. Some of them
includes grinding, polishing, deburring and the most common and popular
method of anodizing. Which is discussed in detail here:
