Powder coating is being used on many major building projects as it is cheaper and thought to be the equivalent of architectural anodising.

IT ISN’T

Powder coating is softer, less durable, and unless done perfectly can peel. Neither can it exhibit the natural metallic lustre of anodising .

1. Softer - Architectural anodising by UA is harder than glass which means it is less prone to damage, wear and tear and can be, if neglected, abrasively cleaned to restore it to its original lustre.  PPC is soft, prone to scratching and cannot be abrasively cleaned.
   
2. Less durable - Anolok™ anodising by UA is fade free and is offered with a lifetime guarantee.   All organic coatings in time lose gloss and colour. Anodising has been used in architecture for more than 80 years;  PPC was introduced in the late 1970’s, much less than 40 years ago.  
3. Anodising is a process where the coating is grown on the surface of the aluminium and cannot ever peel off.  PPC is an applied paint that can peel in service.

 Conclusion

If you want peace of mind and a building exterior that will really last, anodising is the only choice.
