Aluminium extrusion products have become an essential component in a range of industries, offering versatility and durability across various applications. This guide will explore the different sizes, shapes, and applications of aluminium extrusions.
Whether you’re a tradesperson, builder, or a manufacturer, understanding the various aluminium extrusion products available in the market can help you make the best choice for your project.
What Are Aluminium Extrusion Products?
Aluminium extrusion is a process where aluminium is forced through a die to create objects with a specific cross-sectional shape. The result is a lightweight, strong, and corrosion-resistant product that can be cut to precise lengths. Aluminium extruded products are commonly used in industries such as construction, automotive, aerospace, and electronics due to their strength-to-weight ratio and flexibility in design.
When you think of aluminium extrusions, it’s important to consider that they come in a wide range of shapes and sizes. The variety of profiles allows these products to be adapted to numerous applications.
Common Aluminium Extrusion Shapes and Sizes
Check out this list of the most common aluminium extrusion shapes and sizes available:
1. Aluminium Angle
Aluminium angle extrusions are L-shaped products used extensively for structural applications, especially where right-angle joints are required. The two legs of the angle can be of equal or unequal length, making them highly versatile for framing, bracing, or for edging purposes.
Applications
- Construction: Used in frameworks, roof trusses, and general construction tasks.
- Furniture: Often incorporated in the construction of tables, chairs, and shelving units.
- DIY Projects: Great for smaller home improvement tasks, such as creating frames or reinforcing corners.
2. Aluminium Channel
Aluminium channel extrusions have a C-shaped profile and are often used for structural support and framework. They offer excellent resistance to bending and can be used in both horizontal and vertical applications.
Applications
- Building Industry: Frequently used in walls, door frames, and window panels.
- Transport: Used in the manufacture of trailers, buses, and railway carriages.
- Solar Panel Mounting: Ideal for framing and securing solar panels due to their lightweight and rust-resistant properties.
3. Aluminium Flat Bar
One of the more commonly recognised extruded aluminium products is the aluminium flat bar. These bars are rectangular and come in various widths and thicknesses, making them perfect for applications that require strength and durability.
Applications
- Fabrication: Widely used in the manufacturing of tools, frames, and brackets.
- Construction: Ideal for reinforcement in structures, doors, and bridges.
- Automotive: Often used in the construction of vehicle parts that require both strength and flexibility.
4. Aluminium Round Bar
The aluminium round bar is used in a broad range of industries due to its versatility. Available in different diameters, these bars are often used in both heavy-duty and lightweight applications.
Applications
- Machining: Used in the creation of mechanical parts that require precision, such as shafts and pins.
- Automotive: Often employed in the production of car components, including axles and engines.
- Marine: Highly resistant to corrosion, aluminium round bars are ideal for use in marine applications, including boat building and rigging.
5. Aluminium Square Tube
Square tubes offer excellent strength and durability due to their four-sided design. The uniform shape makes them ideal for use in a range of structural applications.
Applications
- Framework: Commonly used in the construction of frameworks for buildings, machinery, and transport systems.
- Furniture: Aluminium square tubes are popular in the design of lightweight but strong furniture pieces, such as tables, chairs, and shelves.
- Fencing: Perfect for use in the construction of fences, railings, and gates due to their sturdiness and weather-resistant nature.
Specialised Aluminium Extrusion Products
Check out this list of specialised aluminium extrusion components available in the market:
1. Aluminium T-Bar
The aluminium T-bar is another extrusion product that has a wide variety of uses. The T-shaped profile provides excellent support, making it ideal for heavy-duty structural applications. The vertical section of the T offers enhanced stability, while the horizontal section provides support.
Applications
- Construction: Commonly used in ceiling and flooring frameworks.
- Transport: Often found in the structural elements of trailers and lorries, providing support without adding excess weight.
- Manufacturing: Ideal for use in machinery and equipment where both strength and light weight are required.
2. Aluminium U Channel
The aluminium U channel is a versatile extrusion with a U-shaped cross-section. This shape allows the material to slide or grip other components, making it ideal for numerous mechanical and industrial applications.
Applications
- Windows and Doors: Frequently used in the construction of window frames and sliding doors.
- Electronics: Used in the housing of electronic components due to its non-corrosive properties.
- Automotive: Employed in the construction of vehicle components, including trim and sealing elements.
Choosing the Right Aluminium Extrusion Product
When selecting an aluminium extrusion product, it’s essential to consider factors such as size, shape, and the intended application. Whether you’re looking for an aluminium flat bar for a construction project or an aluminium round bar for machining parts, choosing the right product ensures durability and performance. Consider the following factors:
- Strength: Different aluminium alloys provide varying levels of strength. If your project requires a high level of structural integrity, opt for extrusions made from a stronger aluminium grade.
- Corrosion Resistance: One of the significant advantages of aluminium extrusion items is their natural resistance to rust. However, certain environments, such as marine applications, may require higher corrosion resistance. In such cases, consider extrusions with additional protective coatings or anodising.
- Weight: Aluminium is known for being lightweight, but the shape and size of the extrusion can affect its overall weight. For instance, aluminium square tubes may provide the necessary strength without adding excessive weight to your project.
- Customisation: Many suppliers, including Custom Aluminium WA, offer customised extrusion profiles. Whether you need a specific length or a particular shape, having the ability to tailor your extruded aluminium products can be crucial for achieving the best results.
Industries That Rely on Aluminium Extrusion Materials
Aluminium extrusions are indispensable in a wide range of industries. Below are some of the key sectors that make extensive use of these versatile products:
- Construction: From window frames to scaffolding, aluminium extrusions play a pivotal role in the building industry due to their strength and corrosion resistance.
- Transport: The automotive and aerospace industries use aluminium extrusion materials for their lightweight properties, which help in fuel efficiency and overall performance.
- Electronics: Aluminium is often used in the housing of electronic devices and cooling systems due to its thermal conductivity and resistance to rust.
- Renewable Energy: Solar panel mounting systems heavily rely on aluminium extrusions for their lightweight and durable properties, ensuring that solar panels are securely mounted for optimal efficiency.
Conclusion
Understanding the different types of aluminium extrusion products can help you make more informed decisions for your projects. Whether you require an aluminium flat bar for construction or a specialised aluminium T-bar for heavy-duty structural support, the right product can offer significant advantages in terms of strength, durability, and corrosion resistance.
