Powder coating is a process that provides a highly durable and aesthetic surface for aluminium profiles. This process is carefully designed to ensure maximum quality and durability of the coating. Here is a detailed description of the workflow:

The profiles we supply are painted in accordance with the QUALICOAT, SEA-SIDE, QUALIDECO and QUALIMARINE certificates, which recognize and guarantee the entire process. We also supply painted sheets, which you can order on our e-shop ALUNET.cz.

We offer RAL, NCS, special, textured, metallic, wood decor and antibacterial colours.

Anodic oxidation, also known as anodizing, is an electrochemical process that increases the resistance of aluminium profiles to corrosion and mechanical wear. This process involves the formation of a thick oxide layer on the surface of the aluminium, which protects the material from the harsh environment and makes it ideal for applications in coastal areas and extreme climatic conditions.

The different colour and finish options also make it suitable for design applications. After cleaning the profile with acid and in an alkaline bath, the aluminium is immersed in an electrolytic solution where it serves as an anode. This creates a shiny, transparent layer of alumina (Al2O3) that is much higher quality than natural oxide. The colour shades are achieved by adding metal salts to the electrolyte. Finally, the surface is sealed in a deionized water bath at 100 °C.

We offer anodized aluminium profiles in many colours and surface finishes, guaranteeing European “EWAA-EURAS” quality in four classes, which differ in oxide thickness and application. In our ALUNET.cz shop you can find anodized profiles in various colours.
