Customization Options Available in Aluminium Extruded Sections

Aluminium extruded sections offer a multitude of customization options that cater to diverse industrial and architectural applications. By tailoring the design, shape, and surface treatment of extruded aluminium profiles, manufacturers can create bespoke solutions that meet specific requirements for functionality, aesthetics, and durability. This article explores the various customization options available in aluminium extruded sections, empowering designers and engineers to optimize their projects.

Alloy and Temper Customization

Aluminium extruders offer a wide range of aluminium alloys to meet varying strength, corrosion resistance, and weldability needs. Each alloy is categorized by a four-digit number, such as 6063 or 7075, with higher numbers indicating increased strength and hardness. Additionally, the temper of the aluminium, denoted by a letter or combination of letters, determines its level of strength and ductility. Selecting the appropriate alloy and temper ensures optimal performance for specific applications.

Profile Shape and Design

The most distinctive customization option in aluminium extruded sections lies in their profile shape. Extruded profiles can be designed to create complex geometries, hollow sections, or intricate cutouts, enabling engineers to achieve precise dimensions and intricate details. This flexibility allows for the creation of custom-shaped extrusions that integrate seamlessly into various applications, from structural components to decorative trim.

Surface Treatments

To enhance the aesthetics, durability, and corrosion resistance of aluminium extruded sections, various surface treatments are available. Anodizing, a process that creates a protective oxide layer, increases hardness, corrosion resistance, and color options. Powder coating, on the other hand, involves applying a colored or textured powder that is electrostatically bonded and cured, providing a durable and weather-resistant finish. Other surface treatments include electroplating, electrophoretic deposition, and thermal spraying, each with its own advantages and applications.

Heat Treatment and Other Processes

In addition to profile design and surface treatments, aluminium extruded sections can undergo various heat treatments and other processes to enhance their properties. Age hardening, a process involving controlled heating and cooling, increases the strength and hardness of certain alloys. Stress relieving, on the other hand, reduces internal stresses, improving stability and dimensional precision. Cold forming, bending, and welding can also be performed on extruded sections to create complex shapes or join them to other components.

Quality Control and Standards

To ensure the reliability and consistency of customized aluminium extruded sections, manufacturers adhere to strict quality control measures. This includes inspections throughout the production process, from raw material verification to final product testing. Conformance to industry standards, such as ISO 9001, guarantees that the extruded sections meet specific performance criteria and quality requirements. Regular audits and certifications provide assurance of quality and reliability.

Applications and Benefits

The versatility of customization options in aluminium extruded sections extends their applications across multiple industries, including construction, automotive,aerospace, and consumer products. Their high strength-to-weight ratio makes them ideal for lightweight structures, while their corrosion resistance and aesthetic appeal make them suitable for architectural facades and interior fittings. In automotive and aerospace applications, extruded aluminium profiles contribute to reducing weight, improving fuel efficiency, and enhancing structural integrity.


Customization options available in aluminium extruded sections empower designers and engineers to create bespoke solutions that meet specific project requirements. From alloy selection and profile design to surface treatments and additional processes, manufacturers offer a wide range of customization options to optimize functionality, aesthetics, and durability. By leveraging these customization options, industries can harness the unique properties of aluminium extrusions to create innovative and tailored products that meet the demands of modern applications.
