Aluminum needs a finish to resist weathering and to look consistent over decades.
Anodizing
Anodizing grows a hard oxide layer from the metal itself. It preserves the metallic look and is very durable, but the colour range is narrower.
Powder coating
Powder coating bonds a coloured polymer layer to the surface. It offers a huge colour range including matte and textured options.
Which to choose?
- Choose anodizing for a natural metallic look.
- Choose powder coating for colour freedom.
