Within the category of aluminum and door industry, there are two protective coating processes in common use to create a protective coating.

1. protection by electrostatic powder coating 

2. protection by anodising process 

Anodising process is not very economical as it requires highly purified aluminum and a large amount of aluminum is wasted in the process. The anodised powder coating provides a highly polished surface with matt effect very similar to the one produced in the anodising process. They are applicable to all aluminum substrates and maintain their gloss in various temperatures.
