What is powder coating?

Powder coating is a coloring and protection technique used on most aluminum exterior products. It consists in projecting powder paints on the metal which polymerize at a temperature of 200°. This process ensures that the aluminum elements are durable and have a high color retention.

The 3 phases of powder coating

1) Preparation of the room to be painted

The aluminum element goes through various treatment baths to remove impurities and ensure perfect fixing of lacquer and color.

2) Electrostatic powdering

A polyester powder paint is then applied via an electrostatic process: a gun will project colored particles charged with static electricity on the aluminum part which will attract them like a magnet. This technique allows a uniform penetration of the color on the whole surface to be painted.

3) Polymerization

Once powdered, the parts are put into an oven at an average temperature of 200° for polymerization. This allows both to harden and stabilize the colored powder.


Powder coating has various technical and aesthetic characteristics, including:

  • Better impact resistance
  • Greater surface hardness
  • Corrosion resistance
  • Very good color retention


The quality of powder coating depends on the professionalism of the applicator. This is why Packit works exclusively with applicators who hold Qualicoat and Qualimarine certifications, a guarantee of quality and a recognized and controlled know-how. All our aluminium products comply with Qualicoat standards.


Although perennial, aluminum exterior elements require bi-annual cleaning to effectively protect them against external aggressions that could damage the painted coating.

Simply wash the aluminum blades in warm water with a soft cloth or a non-abrasive sponge. In case of stubborn dirt, you can add a little mild soap to the water.


Caution! Never use :

  • Products such as gasoline, acetone, alcohol etc.
  • Sanding sponges or abrasives
  • Pressurized jets
