What Is Aluminium Extrusion?
A solid cylindrical block of aluminium, called a billet, is heated to around 400–500°C to make the metal malleable but not molten.
During the extrusion process, a powerful hydraulic ram pushes the softened billet into a container and through a specialized steel die.
The newly formed profile of aluminium is cooled using air or water and is then stretched to ensure it is perfectly straight and to relieve internal stresses.
The extrusion process can create complex cross-sections in a single piece, reducing the need for assembly and mechanical joining.
Aluminium extrusions come in various profiles including trims, angles, bugstrip, interlocks, flat bars, tracks, and square and rectangle hollows.
Common applications include window frames, shower screens, signage frames, and boat gunnels.

Why Aluminium Extrusions Are Widely Used in Australia
Australia’s coastal climate demands materials with superior corrosion protection.
Aluminium naturally forms a protective oxide layer that can be enhanced through anodising or powder coating, providing long-lasting corrosion resistance.
Key advantages:
- High strength-to-weight ratio and design flexibility are primary advantages of aluminium extrusion
- Aluminium is infinitely recyclable with no loss of properties, requiring only about 5% of the energy needed for primary production
- Aluminium is suitable for low-temperature applications because it gains strength as temperatures fall, unlike steel which can become brittle
- Building and Construction is the largest market for aluminium extrusions, used for window and door frames, roofing systems, and modular office partitions
Common Profile Types Available Online
Buyalength.com.au keeps these profiles in stock for immediate dispatch:
- Angles (equal/unequal): 20x20x1.6mm for brackets and ledges
- Flat bar: Ideal for workbenches and trim work
- Square hollow sections: 25x25x1.6mm for shed fit-outs and frames
- Rectangle hollows: 50×25 RHS for privacy screens and ute trays
- Bugstrip and interlocks: Security doors and flyscreens
- Tracks and channels: Wardrobe systems and glazing
The uniform modular dimensions of aluminium extrusion profiles ensure complete interchangeability of connecting elements and accessories, making them versatile for various applications.

Applications Across Industries
Aluminium extrusion is used extensively across multiple sectors due to the material’s durability and corrosion resistance.
Aluminium is considered a preferred material in various applications including aerospace, automotive, construction, electronics, and consumer goods.
Aluminium extrusions are commonly used for heat sinks to dissipate heat from processors and LED lighting due to the metal’s excellent thermal conductivity.
The extrusion process allows for the creation of complex, near-net-shape profiles that are difficult or impossible to achieve with rolling or machining.
Aluminium extrusions can be produced in a variety of shapes and sizes, allowing for customization to meet specific project requirements, which is beneficial for builders and manufacturers.
