Description:
Aluminium corrosion resistance is very good in untreated aluminium. Untreated aluminium has very good corrosion resistance in most environments. This is primarily because aluminium spontaneously forms a thin but effective oxide layer that prevents further oxidation.
Pre painted Aluminium combine the metal’s anti corrosive properties along with a layer of further paint protection giving the lightweight metal a longer lifespan and a vibrant look.
