Types of Aluminium Round Tubes

Aluminium round tubes come in various types, each tailored to specific applications and structural requirements. At Speciality Metals, our range includes:

  • Seamless Aluminium Tubes: This class of tubes is renowned for its uniform strength and precision, which makes them ideal for high-pressure applications, such as hydraulic systems and fuel lines.
  • Structural Aluminium Tubes: These are designed with strength in mind, and are often used in construction and architectural frameworks since they offer stability as well as an aesthetic appeal.
  • Extruded Aluminium Tubes: In the process of manufacturing these tubes, the extrusion process is used, which allows a wide range of complex shapes and sizes to be produced, ideal for intricate designs and custom applications.


Each type of aluminium round tube in our inventory is meticulously crafted to meet diverse project demands. As a result, the specifications vary from model to model, with sizes ranging from small diameter tubes suitable for intricate machinery to large, robust tubes used in construction. As a result, we offer a range of wall thicknesses to ensure that we can provide the precise level of strength and flexibility that you require.

It is also important to note that aluminium round tubes come in different grades, each of which offers its own advantages. It is for this reason that our 6061-T6 aluminium tubes are particularly popular in structural applications due to their high tensile strength, while our 3003-H14 aluminium tubes provide superior formability and are frequently used in automotive components.

Quality Manufacturing Processes

The manufacturing of aluminium round tubes is a process we refine continually to ensure the highest quality. To create the desired shape and size, premium-grade aluminium billets are heated and extruded through a die. As a result, seamless construction and consistent wall thickness are ensured.

Seamless tubes are made from extruded aluminium that is further refined using a drawing method to enhance their properties. Tubes are often subjected to high pressures, so this step is crucial.

Quality doesn’t end with the manufacturing process. Speciality Metals places a high priority on quality control. Our aluminium tubes undergo rigorous testing throughout the production cycle to meet the high standards expected by our clients.
