Finishing Techniques for aluminium windows and doors 

There are different kinds of surface finishing for aluminium. The most popular finish types for aluminium profiles are as follows: 

  • Powder coating
  • Anodizing: A chemical and electrical process combined. It thickens the oxide film for additional protection against corrosion
  • Mechanical finishes: Mechanical Finishes are used for adding a texture to the surface.

Why add a finish to aluminium extrusion 

There are three main reasons for applying an additional finish to your aluminum extrusion:

  • Environmental Protection
  • Metal Preparation
  • Enhanced Appearance

Polyester Powder Coating

The powder coating is a high-performance thermoset coating specifically designed for architectural systems. Powder coating is a very popular finish and is a completely dry paint that does not contain any solvents. 

Powder coatings can be applied horizontally or vertically without noticing any difference in appearance.

 

Gloss levels

Gloss Level Explanation
Matt (30% +⁄ -5%)A matt finish due to the low gloss level is very good at concealing surface imperfections. Due to the textured finish
the surface is more difficult to clean than a surface with a higher gloss level.
Satin (65% +⁄ -5%)A satin finish is not as reflective as the gloss finish and because of this is less likely to show any surface imperfections. Satin finishes also provide a good surface for cleaning and resisting abrasion. Unless stated otherwise this is the standard finish supplied.
Gloss (80% +⁄ -5%)A highly reflective smooth surface. Gloss surfaces due to their highly reflective appearance tend to highlight surface
imperfections.
