Aluminium tube is used for manufacturing lightweight structures, frames, supports, and structural elements. Due to its low weight and natural corrosion resistance, it is suitable for various technical and construction applications.
It is typically made from EN AW-6060 or EN AW-6063 alloys, providing adequate mechanical strength, dimensional stability, and good machinability.
Available in the following variants:

Available Surface Treatments
Aluminium profiles are available in multiple surface treatment options, selected based on operating conditions, exposure level, and the aesthetic requirements of the project.
Powder Coating (Electrostatic Coating)
Powder coating involves applying a coloured powder layer that is thermally cured, ensuring a uniform finish and additional surface protection.
This treatment allows for a wide range of colours and finishes and is frequently used in projects where visual appearance is important, without compromising resistance to environmental factors.
Anodising
Anodising is an electrochemical process through which the aluminium surface is protected by forming a hard, uniform oxide layer. This treatment increases resistance to corrosion and wear while maintaining the metallic appearance of the material.
It is recommended for applications where high durability, long-term stability, and a consistent technical finish are required, both indoors and outdoors.
Mill Finish (Natural)
Mill finish represents aluminium in its original state, without additional surface treatments. It is mainly used in technical or interior applications, or in situations where the profile will be further processed.
This option is suitable for projects where functionality is the priority, and the final finish is applied in later stages.
Aluminium Tube – Available Colours
Aluminium profiles can be supplied in a wide range of colours and finishes, depending on the project requirements. To choose the right option, you can consult the catalogues below, which include options for powder coating and anodising.
