In the realm of industrial design and manufacturing, square aluminium extrusions stand out as a versatile and efficient solution for a wide range of applications. From architectural structures to automotive components, these extrusions offer a unique combination of strength, durability, and aesthetic appeal. To harness their full potential, however, it’s crucial to embrace expert insights and adopt time-tested design tips and tricks.

Design Considerations: Shape and Dimensions

The shape and dimensions of your square aluminium extrusion play a significant role in its performance and suitability for your intended application. Consider the following factors:

Cross-sectional area:

The cross-sectional area of the extrusion determines its strength and rigidity. Larger cross-sectional areas provide greater strength but may increase weight and material costs.

Wall thickness:

The wall thickness of the extrusion affects its resistance to bending and buckling. Thicker walls offer better structural integrity but can impact weight and cost.

Corner radius:

The corner radius of the extrusion affects its appearance and manufacturability. Rounded corners reduce stress concentrations and improve durability, while sharp corners provide a more angular aesthetic.

Material Selection: Alloy and Temper

The alloy and temper of your square aluminium extrusion determine its strength, corrosion resistance, and other properties. Choose the right alloy and temper based on your application’s specific requirements:


Aluminium alloys are available in various grades, each with its own unique properties. Common alloys used for extrusions include 6061, 6063, and 6082.


Temper refers to the heat treatment process applied to the extrusion. Different tempers, such as T6 or T6511, alter the extrusion’s strength and hardness.

Joining Techniques: Mechanical and Adhesive

Joining square aluminium extrusions requires careful consideration of the available techniques. Choose the most appropriate method based on your application’s requirements:


Mechanical joining methods include bolts, rivets, and clips. These methods provide robust connections but may require drilling or punching holes, potentially affecting the extrusion’s strength.


Adhesive bonding uses industrial adhesives to join extrusions. This method provides a clean and versatile alternative to mechanical joining, but it may not be suitable for high-load applications.

Surface Treatments: Finishing and Coatings

Surface treatments can enhance the appearance, durability, and functionality of your square aluminium extrusion:


Anodizing creates a protective oxide layer on the extrusion’s surface, improving its corrosion resistance and aesthetic appeal.

Powder coating:

Powder coating involves applying a dry powder to the extrusion’s surface, which is then baked to form a durable and visually appealing finish.


By embracing expert insights and applying the design tips and tricks outlined above, you can maximize the potential of square aluminium extrusions in your applications. From optimizing shape and dimensions to selecting the right material and joining technique, every aspect of the extrusion process deserves careful consideration. With these guidelines, you can unlock the full strength, versatility, and aesthetic appeal of square aluminium extrusions, enabling innovative and high-performance designs.
