TYPES OF ALUMINIUM SECTION FINISHES.

Aluminium is one of Earth’s most abundant metals known for its lightness, strength and resistance to corrosion. Untreated aluminium extrusions are perfectly adequate for many applications; however, there are many valid reasons to treat the surface of aluminium profiles. These include introducing colour, supplementing corrosion resistance; augmenting hardness; arresting wear-and-tear; and adding reflectivity.

Anodising is a relatively straightforward electrochemical process used to increase the thickness of the natural oxide layer on the surface of aluminium.

Powder coating is a technique mainly used to apply decorative and protective finishes to aluminium profiles through a process that electrostatically charges the powder consisting of a mixture of finely milled resin and pigment, spraying it on to the aluminium extrusion, and then fusing it into a smooth coating in a curing oven.

Advantages of anodised coatings

1. Easy to maintain
2. Anodised aluminium can be cleaned periodically with wa…
