Our Aluminium Products: Channel, Bars & Angles

Aluminium Channel: What is it?

Aluminium channel is a unique type of aluminium extrusion used for a range of structural applications. The main characteristics of a popular aluminium channel include two flanges protruding from one side of a web that often resembles the letter C in cross-section.

How are they made?

The development of aluminium channels comes from pressing round aluminium stock. through a channel-shaped die that uses a high-pressure ram.

There are two main types of extrusion methods:

  • Direct extrusion
  • Indirect extrusion

Direct extrusion corrects the die in place while the ram presses the billet through a hollow die. Indirect extrusion keeps the billet static while forcing the die, within a hollow ram, along its length.

These three processes can be used to either method:

Hot Extrusion

The process of extrusion takes place after the aluminium stock is heated to full plasticisation regularly performed within a vacuum to avoid oxidation.

Cold Extrusion

Handling of billets into extruded shapes takes place at or near room temperature.

Warm Extrusion

Extrusion happens after heating stock to a temperature between 800º and 1800º F, depending upon alloy composition.

Straightening of aluminium extrusions on a stretcher follows the formation process, making them prepared for shipping and use.

What is an aluminium round bar?  

Aluminium round bar is a lengthy, cylindrical metal bar stock that has various industrial and commercial applications. The most popular application is shafts. Round bar is available in many metal types including Hot-Rolled Steel, Cold-Rolled Steel, Aluminium, Stainless Steel and more.

Aluminium Round Bar can be purchased online at aluminium online. The diameter can be filtered to be cut to your preferred specification.

What are aluminium round bars used for?

Aluminium round bar is very easy to machine, and complex parts can be changed quickly with brilliant results. Drilling and cutting are feasible with basic DIY equipment and smaller diameters can be easily and precisely with a hacksaw.

This aluminium rod is a popular product due to its lightweight, its strength to weight ratio, excellent anti-corrosion properties, and ease of machining, therefore, its uses are extremely varied and include precision turned parts, wheels and pulleys, fasteners, machine components.

Aluminium Flat Bar

An aluminium rectangle bar is also known as flat bar (and as ‘strip’).

This ‘rectangular bar’ gets its name from the cross-section of the profile which is measured by its width and then by its depth.

What are Aluminium Flat Bars used for?

Supplied in both 6063 or 6082 grade aluminium, it is lightweight and has good strength to weight properties that make it appropriate for many uses including manufacturing jigs, machine parts, shop fitting, frames, road transport, and general fabrications; our aluminium rectangular bar also has brilliant corrosion resistance.

Aluminium Equal and Aluminium Unequal Angles

Aluminium equal angle and aluminium unequal angles are used primarily to control, safeguard, strengthen and support different surfaces. The smaller angles are perfect for small projects including wall corners, counters, and worktop edges. These extrusions provide excellent corrosion resistance and a fantastic surface finish. Other typical uses for equal angles include:

  • Window frames
  • Door designs
  • Shop fittings
  • Rails, posts and balustrades
