Guide to Hollow Aluminium Extrusions

Hollow aluminium extrusions are commonly used in construction and fabrication projects across various industries. Their strong design and durability make them ideal as supporting structures. They are also lightweight due to their hollow interior, which is why they’re particularly useful for a variety of construction and fabrication projects. In this guide, we’re going to delve into the unique properties, differences and applications of this aluminium extrusion. By the end of it, you should have an idea of how they can benefit you in your next project.

How Is Hollow Aluminium Extruded?

The extrusion process involves creating voids within the material, which is how it attains its hollow form. It begins with the aluminium being warmed up and prepared. Then the aluminium is pushed through a special mould to create the space in the middle, allowing for the extrusion to gain its lightweight, yet sturdy, quality. After this step, aluminium cools down and within that time it gains its sturdy properties. Once it has finished cooling down, a few final touches are made to ensure it is straight and then it is cut into different lengths.

In general, the process of how hollow extrusions are made is by using special equipment and high temperatures allowing for the extrusion to be strong, while also making it easy to handle.

What is the Difference Between Solid and Hollow Aluminium Extrusion?

The major differences between solid and hollow aluminium extrusions has to deal with the extrusion process. A solid extrusion is of higher strength due to its solid state and having no voids or openings. As stated in the name, a hollow aluminium extrusion comes with a void internally, therefore weighs less and has a wider range of uses.

Both solid and hollow aluminium extrusions have different uses and purposes. Solid extrusions are easier to manufacture as they don’t require the void in the centre. While hollow extrusions are slightly more complicated to make. As you can imagine, solid extrusions tend to be heavier while the extrusion process to make aluminium extrusions hollow makes them lighter, as they are constructed of less metal matter. This means solid extrusions have greater strength and rigidity due to their structure.

In terms of their use, solid extrusions are common when structural strength is the top priority and weight isn’t an important factor. Heavy infrastructure, construction materials and tools are just some of the products and industrial applications that utilise solid aluminium extrusions. While hollow extrusions are more versatile and lighter in weight, they tend to cost a bit more due to being more difficult to manufacture. Depending on your needs one may be more necessary than the other, but both can be used in many different ways.

Properties of Hollow Aluminium Extrusions

There are several reasons why hollow aluminium extrusions are used frequently for a wide variety of projects, the first of which is due to their unmatched strength-to-weight ratio. Aluminium is also resistant to corrosion, which means not only are they durable but long-lasting as well. Whether it’s rectangular box sections, square box sections or round tubes, hollow aluminium extrusions have a wide range of uses due to their unique attributes.

Environmental Benefits of Aluminium Extrusions

Whether it’s hollow or solid, aluminium extrusions are highly recyclable and still maintain their properties even when melted down and recast. So, regardless of the project, they remain a highly sustainable material choice for those looking to make an environmentally friendly choice. The act of recycling aluminium extrusions benefits the environment and reduces your carbon footprint. Recycling aluminium also decreases the demand for the creation of new building materials. It’s an important reason why aluminium extrusions are considered one of the more sustainable options for building materials.

Applications of Hollow Aluminium Extrusions

Hollow extrusions tend to be more versatile, so they’re used in projects that require sturdy material that isn’t as heavy. Construction applications like doors, windows, building components and automotive parts all feature hollow aluminium extrusions. Its versatility makes it useful for a wide variety of applications and is widely used across a variety of industries.

Nearly anywhere you go you can find examples of hollow aluminium extrusions being displayed. Street signs, fences, light poles and even many buildings’ infrastructures all feature these extrusions. Its applications are nearly endless as very few building materials can provide the same structural integrity while also having lightweight qualities.
