Understanding Aluminum Profiles and Extrusion

Bulk plastic deformation occurs during the aluminum extrusion forming process. Before molding, an aluminum billet is heated to a predetermined temperature that is just below the melting point of the material. This helps the material flow more easily.

After being heated, the billet is pushed through a tooling die that is intended to mold and form it into the appropriate profile cross section. In layman’s terms, this industrial extrusion process is similar to cooking techniques used to make different types of pasta.

Advantages of Aluminum Extrusion

Because of its mechanical properties that make it perfect for shaping and forming metal from billet sections, aluminum is a material that is frequently specified for use in extrusions and shape profiles.

Furthermore, aluminum has a melting point that is typically half that of regular steel, and its great malleability allows it to be easily formed into a variety of sections without requiring a lot of energy during the tooling or forming process.

Because of these two features, the energy footprint of the aluminum extrusion process is relatively small, which results in low costs for tooling and manufacturing. Lastly, aluminum is a great material for industrial applications due to its high strength to weight ratio.

Aluminum Extrusion Profile Types

Different thicknesses of complex aluminum extrusion profiles can be produced in a wide range of designs. Depending on the requirements of the final application, these profiles can have a range of intricate void areas that meet any performance weight requirements.

The hollow beam profile, which is essentially a square profile variant, is the most widely used kind of aluminum profile. Triangular, L-shaped, and single-radius profiles are among other profile kinds.

Surface Type

Occasionally, the surfaces of the profiles have tiny, imperceptible lines that are a result of the extrusion process. These lines are caused by the extrusion tooling, and they can be eliminated by specifying extra surface treatments.

To enhance the surface finish of the profile section, a few secondary surface processing procedures, such as face milling, can be carried out following the primary extrusion forming process.

By lowering the total surface roughness of the extruded profile, these processing steps can be set to enhance the component profile by improving the geometry of the surface. These treatments are usually specified in situations where tight control over mating surfaces is required or when exact placement of the parts is required. 

Additionally, surface treatments can strengthen the profile’s resistance to corrosion, increase its hardness, or even give the extrusions more electrical insulation.

Uses of Profiles Sections

Aluminum Construction Profiles: These profiles are widely employed for a variety of structural and architectural applications in the building sector. They are employed in the construction of roofing systems, curtain walls, window and door frames, and structural elements.

Industrial Aluminum Profiles: They are utilized in the building of workstations, conveyor systems, machine frames, and safety guards. These profiles’ adaptability makes it simple to customize them to meet specific industrial requirements.

Aluminum Formwork System: Concrete constructions including walls, slabs, columns, and beams are made in the construction sector using aluminum formwork systems. These systems are simple to put together and take apart, lightweight, and strong.

Building Systems: In the construction sector, aluminum building systems find extensive use. They are employed in the construction of facades, cladding, ceilings, and partitions.


To sum up, aluminum is a great structural material that works well for profile extrusions, and extrusion aluminum profiles are adaptable and suited for usage in a range of applications.

Aluminum extrusion profiles provide a dependable and effective solution for a range of applications, whether they are utilized in the building, transportation, electronics, or industrial sectors.
