Powder coating


What is powder coating and why to choose it?

Powder coating is a process in which a film of decorative powder is laid on the aluminum surface to color it and protect it from external factors. This process takes part in three main steps:

a) Pretreatment, in which all undesirable agents are removed from the aluminum surface, rendering them ready to be dyed

b) Dying, in which colored power is sprayed on the profiles with the use of electrostatic guns.

c) Curing, during which the powder is polymerized and stabilized on the surface of the profile.

Powder coating is the most popular surface treatment available, as it provides:

  • Unlimited aesthetics options: the powder coating pallet is practically endless
    • Coloring: almost all combinations of color and gloss are available
    • Texture: powders come with either smooth or textured surface
  • Color Stability: powders are categorized in two basic categories in terms of color and gloss degradation due to sun’s radiation, Class 1 and Class 2, with the second one being 3-5 times more resistant.
  • Durability: the texture of the powder diversifies its resistance in scratching and therefore the profiles handling and everyday use.
    Textured colors are way more resistant in that aspect, while smooth colors are more vulnerable.
    Note: Please check Preanodizing section to explore new possibilities
  • Ease of Maintenance: Simple rinsing or mild soap and water cleaning will restore a powder coated surface to its original appearance
