Choosing the Right Aluminium Extruded Sections for Your Project

Aluminium extruded sections are essential components for a wide range of industries, offering versatility, durability, and lightweight performance. Choosing the right profiles is crucial to ensure optimal functionality and aesthetic appeal. This article provides an in-depth guide to aid you in selecting the perfect aluminium extruded sections for your project.

Considerations for Choosing Aluminium Extruded Sections

Material Properties

Alloy composition: Different aluminium alloys exhibit varying strengths, corrosion resistance, and machinability properties. Select alloys based on your specific requirements, such as 6061 for high strength, 6063 for corrosion resistance, or 7075 for aerospace applications.

Temper: Tempering processes alter the mechanical properties of aluminium. Choose tempers based on desired strength, hardness, and ductility. Annealed tempers provide good formability, while T4 tempers offer high strength and T6 tempers provide maximum hardness.

Design Considerations

Cross-sectional shape: Determine the optimal cross-sectional shape based on the desired functionality and load-bearing capacity. Common shapes include tubes, channels, angles, and complex custom profiles.

Tolerances: Specify dimensional tolerances to ensure precision and consistency in the extruded sections. Tight tolerances are essential for applications requiring precise fits, while wider tolerances may suffice for general-purpose use.

Surface finish: Choose the desired surface finish to enhance durability and aesthetics. Anodizing or powder coating can provide corrosion resistance, color options, and improved wear resistance.

Manufacturing Capabilities

Extrusion capability: Assess the extrusion capabilities of the manufacturer to ensure they can produce the desired shapes and sizes. Consider factors such as press capacity, die availability, and minimum/maximum wall thicknesses.

Value-added services: Determine if the manufacturer offers additional services such as cutting, drilling, punching, and assembly. These services can save time and cost during fabrication.

Sustainability Considerations

Recyclability: Aluminium is highly recyclable, making it an environmentally friendly option. Choose manufacturers who prioritize recycling initiatives to minimize waste and promote sustainability.

Energy efficiency: Consider the energy consumption during the extrusion process. Choose manufacturers with modern and efficient equipment to reduce environmental impact.


Choosing the right aluminium extruded sections is essential for the success of your project. By considering factors such as material properties, design considerations, manufacturing capabilities, and sustainability, you can select the optimal profiles to meet your functional, aesthetic, and environmental requirements. With the guidance provided in this article, you can make informed decisions and ensure the best possible outcome for your project.
