What is an aluminium square bar or rod?

An aluminium square bar or aluminium square rod as it is also known, is a solid length of aluminium with a square cross-section. It is a specialised form of aluminium extrusion stock, used in a variety of applications, including construction, machinery, architectural design and more. All aluminium square bars supplied by Aluminium Online are 6000 grade, meaning they are ideal for internal and external usage thanks to their strength-to-weight ratio and high corrosion resistance.

They are commonplace in the construction industry, being used as support structures in buildings and as frameworks. They are also a popular choice in the transportation industry, marine applications, fencing and barriers, decorative purposes and, as aluminium is a good conductor, is often used in electrical capacities.

What’s the difference between an aluminium square bar and square tube?

As the name suggests, an aluminium square bar is a solid extrusion of aluminium. An aluminium square tube, however, is hollow with a square shaped cross-section, like tubing. Because of this, they have different uses – aluminium square bars are used predominantly in construction, whereas square tubes are instead used for structural support where there are weight restrictions because of their hollow nature.
