Guide to Joining Aluminium Extrusions

Aluminium extrusions are versatile objects that are made to assist in a wide range of purposes. The process of joining together aluminium extrusions can help in creating a stable structure without the need for many joints or other components. Whether it’s a DIY project or something more complex, joining aluminium extrusions has proven to be a cost-effective and time-saving way to complete any project. Aluminium extrusion joining methods can vary depending on the job, read on to see some of the different ways it can be done.

Methods of Joining Aluminium Extrusions

So how do you connect two aluminium extrusions together? Well, that depends on the type of extrusion. There are a few time-tested methods of joining aluminium extrusions. Albeit different, each of these methods can be helpful in future projects where stability and time-saving are key factors.

Welding: This is for those who want a more permanent design. You will likely need to seek a professional to assist, therefore it’s one of the more costly methods of joining aluminium extrusions. Welding requires the use of high heat, so safety is of the utmost importance. In jobs that require welding, an aluminium equal angle is often used as it’s simple to weld and shape. It forms a 90-degree angle and is commonly used in construction and ventilation systems.

Mechanical Fastening: Chances are you’ve used the following method. The tightening of screws, bolts and rivets is the most common form of joining together two extrusions. This process allows for objects to be secured to a solid surface. It’s featured in the assembly of household items right the way through to the largest of industrial jobs.

Adhesive Bonding: Not too dissimilar from using glue to hold an item into place, the practice of adhesive bonding as a means of joining aluminium extrusions follows the same principles. It’s one of the easier forms of joining extrusions as there’s no professional assistance required, but you should still take caution when using adhesives of any kind and ensure that the bonding is sturdy enough for the project.

T-Slot Connections: Aluminium tee sections are made with joining in mind. T-Slot connections help connect the extrusions at a right angle. They’re considered lightweight yet sturdy. Due to their sturdiness, they are used in equipment frames and mounting systems.

Threaded Inserts: These are small adapters that allow you to screw into a threaded hole in aluminium extrusions. They’re perfect for joining two or more objects and creating strong connections in aluminium structures. Threaded inserts are featured in furniture items and provide easy assembly and disassembly.

How Do You Attach Things to Aluminium Extrusions?

Depending on the project, the method you use to attach things to, or join, aluminium extrusions will be different. Each of the following methods requires a certain amount of precision. Below are three of the most common ways to attach things to aluminium extrusions.

Clamp-On Mounting: Requires no drilling. To attach, open the clamp and adjust it to be fitted before tightening it into place.

T-Slot Fastening: Position the aluminium extrusions with the T-slots facing towards the area you want to connect. Insert the bolts and proceed to tighten them.

Adhesive Bonding: Simply apply adhesive on the surface and carefully align the extrusions to join them together. Be careful and follow all the instructions regarding use of the adhesive.

Screwing into Aluminium Extrusion

Fabrication such as drilling is not easy when it comes to aluminium extrusions. This involves choosing the right screws that are compatible with the aluminium and drilling a pilot hole if there are no pre-drilled holes. Then you would have to position the bracket you’re attaching to the extrusion to ensure the holes line up. Finally, you would use your screwdriver or drill to tighten the screws into the hole you’ve made. There’s no room for error when it comes to screwing into aluminium extrusions, therefore it can be more cost-effective and time-saving to recruit a professional.

It can be a daunting task to do some of this on your own, so we offer fabrication services such as drilling, countersinking and pressings to help with the exact needs of your project.
