Aluminum channels are used in a variety of construction applications. These channels contain two projections from the core that resemble the letter-C. The manufacturing process of these channels includes compressing rounded aluminum stocks called logs or billets. It is done through a die under a high-pressure ram. There are two methods to do the extrusion, namely- the direct and indirect methods. Moreover, the extrusion of channels can be of three types- hot, warm and cold extrusions.

How Are The Different Extrusions Made?

Hot aluminum extrusion:

The aluminum stock is initially used to complete the process of plasticising (over 800º and 1800º F, based on its composition). After this, the extrusion is carried out. The process happens in a vacuum to avoid the oxidization of the metal.

Warm aluminum extrusion:

They heat the stock to temperatures between 800º and 1800º F, based on the composition of the aluminum. Following this, the extrusion process is carried out.

Cold aluminum extrusion:

They produce the logs at room temperature (or similar temperatures).

What Are The Different Types Of Aluminum Channels?

The structural shape of the aluminum channels is usually one of the below:

  • U channel -(thickness: up to 0.03)
  • J channel-(thickness: up to 0.03)
  • C channel – (thickness: between 0.003 to 0.500)
  • Hat channel – (thickness: 0.005)
  • T channel
  • Bars
  • Tubes
  • I beam
  • Angle

What Are The Industrial Uses Of These Channels?

Hat Aluminum Channels

  • This type of channel is perfect for flattening ceilings or masonry walls.
  • They give a flat and sound surface to the construction.
  • Concrete wall and exterior wall applications use hat aluminum channels.
  • They are also suitable for architectural curtain-wall applications.

U And J Channels

  • These channels are used in manufacturing frames, slides, rails, rims, railings, tracks, protective edges and decorations.
  • They are also used in architecture.
  • U and J channels are used in window sheets and door edges.
  • You can find these channels in many home appliances.

C Channels

  • C channels are perfect for manufacturing encircling covers.
  • They are also used for industrial purposes in factories.
  • Railings and posts are made using C channels.
  • C channels are also used in making boats, buses and trains.

What Are The Benefits Of Aluminum Channels?

Light weight:

Aluminum is a lightweight metal; still, it is highly durable and sturdy, despite its lightness. It helps in making light load bearings.

Insulation properties:

Aluminum is also a great conductor of heat and electricity. They are better electrical conductors than copper. Hence, these channels are commonly used to manufacture high capacity overhead power cables (lines).

Corrosion resistant:

This metal is also highly resistant to corrosion and rust as it forms an oxide layer when exposed to air. This protects the channels against rust and corrosion. Its effectiveness can be increased by anodizing the metal.

Heat shielding:

Aluminum also possesses high heat shielding and transfer properties. Moreover, it is a lot more rigid yet lightweight. Hence, these channels are apt for manufacturing aerospace applications.

Fire resistant:

Aluminum does not spark during electricity conduction. So it is used in making highly flammable or explosive appliances.

Used in electrical appliances:

The non-magnetic property of aluminum is also beneficial for electrical appliances. Aluminum also has low toxicity and very high reflectivity.


Finally, aluminum is entirely recyclable. It is equivalent to virgin material that is free of degradation. Hence, it requires only around 5% of the energy needed to recycle the other raw materials.


You can also use aluminum channels in the construction of various buildings and flats. Metal channels serve a lot of purposes to attain design, structural and industrial limits. Aluminum is a unique metal and offers a variety of benefits. Aluminum channels are highly affordable and befitting any budget, and one can purchase them online for convenience. Additionally, they can be customized in any shape or size. Hence, aluminum channels are becoming popular, replacing steel and copper.
