Thermal lacquering

Is it a surface treatment of the aluminium profiles through a painting process based on thermal-curable polyester dust, applied after a pre-treatment cycle and whose main purpose is to protect and prepare profiles for painting.

The resulting coating is called thermal-lacquering and its thickness should be superior to 60µm. 

In the lacquering process the aluminium profiles are submitted to several tests and trials, namely: Brightness | Adherence | Penetration Hardness | Resistance Filling | Chock Trial | Folding with Cylindrical Mandrel | Coating Thickness | Tones | Machu Trial.

Wood-effect finishing:

This thermal-lacquering process allows an exceptional adherence of colour layers in any aluminium profile or plates. The constant research on the several painting products guarantees excellent aesthetic quality and maximum resistance to climate conditions.  It does not entail special maintenance, just the usual periodic cleaning. It is environmental-friendly, and all products used in the Wood-Effect Finishing are non-toxic and fully recyclable.


It is an electrolytic process which promotes the formation of a decorative and protective, uniform and controlled layer of aluminium oxide on the aluminium surface.

The process begins with the clamping of the profiles in the suspensions, which, in their turn, are bolted to the anodic bar that is moved along an airbridge over the treatment bowls.

In the anodisation stage, the following tests and trials are conducted: Layer Thickness | Colour Comparison | Admittance | Colouring Drop | Resistance to Abrasion | Loss of Mass.
