Anodising (anodised aluminium)

Anodising is a finish for aluminium in which an electrochemical process grows a hard, protective oxide layer into the surface of the metal itself — unlike paint or powder-coating, which sit on top. The result is a very durable, corrosion- and wear-resistant, colour-stable finish that won't peel or flake, resists UV/fading well, and keeps a natural-metal or coloured metallic look — which is why it's used on quality aluminium windows, facades and architectural fittings in the Gulf sun. It differs from powder-coating (a sprayed, baked colour coat): anodising is thinner, integral to the metal, and excellent for durability and a metallic aesthetic, while powder-coating offers a wider colour range. Both need good aluminium and proper prep; an aluminium finishing specialist can advise which suits the job.
