Types of Aluminum Channels and Their Uses

Aluminum channels have various uses across many industries thanks to their strength, corrosion resistance, and durability. These channels are versatile and widely used in construction, manufacturing, automotive, aerospace, and many other industries. Aluminum channels are extruded metal products made from aluminum alloy with a uniform cross-section along their length. They come in various shapes and sizes, making them suitable for various applications.

Many aluminum channels are on the market today, each with its uses and advantages. Some of the most common aluminum channels include:


U-channels are commonly used in the construction industry and many other engineering projects. As the name implies, they have three flat sides, with the two parallel sides meeting the third side at 90 degrees, forming a U shape. U channels often support and reinforce beams, panels, and other structures. They can also be used in making decorations, rims, railings, slides, and tracks.

They are used to create frames, edges, and joints in various materials. U-channels come in different sizes and thicknesses, allowing them to be customized to the project’s specific needs. They also have excellent electric resistance, thermal expansivity, a high melting point, and good density.

Aluminum channel stock from FastMetals is extremely strong and durable, making it a great choice for many industrial, commercial, and residential applications. The company makes U-channels that are lightweight and easy to install, making them a cost-effective solution for many projects.

C-channels have a c-shaped profile and are excellent for use in the construction industry. They are lightweight, corrosion-resistant, and have excellent thermal conductivity, making them an ideal choice for applications that require durability, strength, and heat dissipation.

The construction industry mainly uses them as framing material for walls and ceilings. The c-channels are also used in the automotive industry to form and strengthen car bodies and create frames for car doors. They are also used for structural support, encircling covers, framing, railings, and posts to strengthen different objects.

In addition to their strength and durability, c-channels are also easy to cut, form, and weld, making them a popular choice for many applications. C-channels are available in different lengths, widths, thicknesses, and alloys to meet the needs of any application. They can be easily cut and customized to fit any project.

Hat Channels

A hat channel is a popular type of aluminum channel that is used in a wide range of applications. It is named as such because of its distinct shape; it has a hat-like appearance, with two long sides and two short sides. This particular shape makes it ideal for many uses, such as framing, trimming, and edging.

It is often used in constructing windows and doors, allowing for a secure and stable fit. Additionally, the hat channel can be used to construct panels, cabinets, and other projects. It is also commonly used in the construction of roofs and the installation of plumbing and electrical components. Due to its shape, it can provide a strong, secure connection between two components, making it a great choice for many projects.

Hat channels are lightweight and have a high strength-to-weight ratio, making them ideal for many applications in industries, factories, and markets. Other uses of H channels include:

  • Architectures use it in curtain wall applications.
  • Concrete wall applications
  • Exterior applications
  • For furring or leveling of masonry walls and ceilings

Aluminum channels find a variety of applications because of their unique properties. These channels can be categorized into three main types: structural, architectural, and electrical.

Structural aluminum channels are used to construct buildings and bridges, providing strong support and stability. Architectural aluminum channels are used to decorate buildings, such as window frames, curtain rails, and door frames. They are non-structural and can be used for framing, trimming, and other design elements.

Electrical aluminum channels are used to safely and efficiently route wiring, providing a secure and durable conduit.

General construction

In general construction, aluminum channels are often combined with other materials, such as steel and wood, to create complex structures. They are also commonly used for decking, stairs, and railings.

 Industrial applications

Industrial-grade aluminum channels are typically used in the construction of industrial buildings. They are commonly used in applications such as roof trusses, wall framing, and structural equipment supports. This type of aluminum channel is made from an extruded aluminum alloy and is available in various sizes and thicknesses. They are known for being lightweight and easy to install, making them a cost-effective option for many businesses.

Aluminum channels are also used in many industrial applications, such as in manufacturing parts for the automotive and aerospace industries and in producing food and beverage containers. The lightweight and durable properties of aluminum make them a popular choice for a variety of uses.

Buying aluminum channels

Many companies out there claim to manufacture high-quality aluminum channels, but their products never live up to the promise if you want aluminum channels, purchase from a reputable company like FastMetals.

FastMetals is a trusted name in the field of aluminum extrusion and manufacturing. They specialize in custom-made aluminum extrusions for various applications and are known for their high-quality products and excellent customer service. Their products range from aluminum channels for automotive and mechanical applications to aluminum channels for building and architectural applications. They strive to produce durable, cost-effective, and aesthetically pleasing aluminum channels that can be used in any application.


Aluminum channels have a variety of useful applications. Each type of aluminum channel has its unique characteristics and applications. Before buying any type of aluminum channel, consider how you will use it. If you can’t decide, let a qualified contractor help you.
