Aluminium channel profiles are an adaptable structural element that typically comes in the form of U or C shapes and are made using the extruding process. These profiles combine lightweight strength, resistance to corrosion and exceptional mechanical functionality.  

Why aluminium is a great choice? 

Aluminium is one of the most abundant raw materials on the planet, possessing amazing properties including a high strength-to-weight ratio, corrosion resistance, electric and thermal conductivity and is also 100% recyclable. In fact, 75% of the world’s aluminium has been recycled from pieces created when it was originally discovered.

Browse our wide range of aluminium profiles and discover your ideal shapes and sizes to complete your job.


Great strength to weight ratio


Excellent corrosion resistance


One of the planets most abundant raw materials


Almost infinitely recyclable


Aluminium channel sections sizes – metric and imperial systems

At LA Metals, we supply measurements for all our aluminium profiles in both metric and imperial measurements. Though the majority of the world uses the metric system for weights and measures, some still choose to employ the imperial system. If you find yourself working with a company from abroad or maybe someone on your team is more used to one system over the other, we supply the measurements next to each other to ensure whichever system the required measurements are written in, you can be sure to receive a perfect fit.
