Surface treatment, surface coating, anodising, anodisation


Surface treatment, surface coating and anodising play a key role in the production of aluminium materials and are of fundamental importance for the manufacture of high-quality products. These processes are not only standard procedures, but also decisive factors for success in various branches of industry. Their essential role is to protect aluminium surfaces from corrosion and other damaging influences, enhance their aesthetic appeal and optimise their functional quality. In this way, they help to meet and exceed the expectations and requirements of customers in a wide range of industries.

Surface coating

Surface treatment is the first step in this process. Here, the aluminium surface is carefully prepared to remove impurities, oxidation and other defects. This is usually done by mechanical grinding, brushing or pickling. Thorough preparation is crucial as it forms the basis for a uniform and high-quality anodised layer.

This is followed by the actual anodised coating. This step is an electrochemical process in which the aluminium surface is oxidised in an acid solution to create a thin, porous oxide layer. This layer is then converted into a stable, hard anodised layer in a second step using an electric current. The thickness of this layer can vary depending on the requirements and intended use. Anodised coatings offer excellent corrosion resistance, wear resistance and a wide range of colour options.

These are essential processes that significantly influence the quality and functionality of workpieces in modern industry. One of their most significant advantages is the effective protection against corrosion, which significantly extends the service life of products and reduces maintenance costs. Furthermore, these processes enable a wide range of aesthetic improvements, ranging from smooth, shiny surfaces to textured, appealing designs. In addition to external enhancement, they contribute to the functionality and adaptability of workpieces by optimising specific properties such as adhesion, conductivity and friction characteristics. This makes them indispensable tools in a variety of industries and applications where customised surface requirements are crucial.

surface is everything


Surface treatment and coating are not only aesthetic improvements, they also enhance the performance and durability of workpieces in many ways. Their adaptability, versatility and contribution to increasing quality make them crucial processes in modern industry.

  • Increased resistance to wear and tear.
  • Possibility of targeted improvement of functions.
  • Applicable to various materials and industries.


Anodising is a process used to protect and refine aluminium surfaces and give them special properties. This process is of central importance in aluminium processing and is used in various branches of industry.

Anodising is an electrochemical process in which the aluminium surface is oxidised in an acidic electrolyte solution. This leads to the formation of a thin, porous oxide layer on the surface of the aluminium. This oxide layer is the key to improving the material properties.



  • Anodisation can protect, refine and impart special properties
  • Our baths allow us to process workpieces measuring up to 105 x 295 cm.

      Protect, refine, design


      • The formation of a protective oxide layer on the surface provides excellent protection against corrosion.
      • Anodised surfaces are more resistant to wear, scratches and abrasion.
      • It is an environmentally friendly coating method as it does not require any harmful solvents or chemicals. 
      • The thickness of the oxide layer can be customised to achieve specific functional properties.
