Corrosion Resistance – Aluminum channel inherently resists corrosion through a naturally forming protective oxide layer that shields the base metal from oxidation and environmental damage. This self-healing protective barrier makes extruded aluminum channel highly suitable for outdoor applications, marine environments, and areas exposed to moisture or chemicals.

Design Flexibility – The extrusion process used to create aluminum channel provides tremendous design flexibility. Engineers can develop custom profiles with precisely the characteristics needed for specific applications, incorporating complex cross-sections and integrated features directly into the design.

Fabrication Advantages – Working with aluminum channel offers advantages during fabrication and assembly as the material is readily cut, drilled, bent, welded, and machined using conventional tools. This workability makes on-site modifications straightforward, allowing for adjustments during installation without specialized equipment.

Aesthetic Appeal – Extruded aluminum channel presents a clean, modern appearance with a natural silver-gray finish that complements contemporary architectural and product designs. For enhanced visual appeal, aluminum channel can be treated with various surface finishes, including anodizing, powder coating, and painting in virtually any colour.

Sustainability – Aluminum channel is 100% recyclable without loss of properties, with the recycling process requiring only about 5% of the energy needed for primary production. The long service life and minimal maintenance requirements of extruded aluminum channel contribute to sustainable practices by reducing replacement frequency.

Thermal and Electrical Properties – Aluminum channel efficiently conducts heat, making it valuable for applications that require heat dissipation or thermal transfer. Unlike some materials that become brittle in extreme conditions, aluminum channel maintains its strength and ductility across a wide temperature range.

How is Aluminum Channel Made?

Aluminum channels are typically formed and produced through extrusion. During the extrusion process, an aluminum billet is first heated until it becomes soft and malleable, reaching temperatures between 400-500°C. Once heated, hydraulic presses apply tremendous pressure (sometimes exceeding 10,000 tons) to push the material through specially designed steel dies. As the aluminum exits the die, it takes the exact shape of the opening. The newly extruded aluminum channel is then cooled, straightened, and cut to standard lengths before undergoing finishing processes such as anodizing or painting.

Types of Aluminum Channel

There are three standards of aluminum channel:

• American Standard aluminum channel features tapered legs that become thinner toward the edges, providing enhanced structural strength for load-bearing applications.
• Aluminum Association channel is characterized by straight, non-tapered legs with square corners, creating clean, precise fits when joining with other materials.
• Standard Channel features consistent wall thickness throughout with sharper inner and outer corners, making it ideal for applications requiring precise dimensions and a clean aesthetic appearance.

Aluminum channels have inside-radius corners that give them their distinctive channel shape. These products are one-third the weight of steel but offer similar durability and reliability. All aluminum channel types offer a high strength-to-weight ratio, stress resistance, and are non-magnetic, and can have both round and square inside corners.

There are several types of aluminum channel, including architectural channels, aluminum C channels, aluminum Z channels, aluminum U channels, slide track channels, and hat channels. Each of these can be cut to fit specific use cases.

• Aluminum Hat channels. This type of aluminum channel is composed of two horizontal flanges that extend outward and two vertical dimensions, giving it a hat-like profile. Commonly used in buildings to level uneven walls and ceilings, maintaining the structural integrity.
• Aluminum U channels. These aluminum channels typically feature additional fabrication following extrusion. Aluminum U channel is lightweight, strong and resistant to corrosion. They have a simple design consisting of a “U” shape with two legs that are parallel and perpendicular to the base.
• Aluminum J channels. J aluminum channels are attractive, durable and easy to mount, making them ideal for framing mirrors or building store fixtures. These feature a unique “J” shape, with one leg perpendicular to the base and the other leg angled at 45 degrees.
• Aluminum C channels. C channel aluminum, like other channels, is available in many different lengths and thicknesses. These have a simple design consisting of a “C” shape with one leg longer than the other, giving them a flatter profile. Commonly used as an aesthetic addition to spruce up the sophistication of a project. Typical applications include framing, covers, decoration, railings and tracks.
• Aluminum Z channels. Has legs or flanges that extend in opposite directions from the web to create the Z profile. There are several Z channel variations, commonly referred to as clips or bars. Clips have a very small web, whereas bars exhibit the typical Z channel profile. Applications for Z channels can include metal and wood roofing.
• Aluminum F channels. This extruded aluminum channel features a profile resembling the letter “F” with a vertical web and two horizontal flanges extending in the same direction. Commonly used in signage installation, panel mounting, and creating clean edge finishes in architectural applications.
• Aluminum H channels. H channels have a distinctive profile resembling the letter “H” with two parallel vertical webs connected by a horizontal member. These versatile channels excel at joining panels or sheets and provide exceptional structural support while allowing for thermal expansion.
• Aluminum I channels. I-shaped aluminum channels feature top and bottom flanges with a vertical web connecting them, similar to traditional steel I-beams. They excel in applications requiring significant load-bearing capacity while maintaining aluminum’s lightweight properties, making them ideal for structural frameworks in construction, transportation, and industrial equipment.
• T-Slot Aluminum channels. These specialized channels feature T-shaped slots running along their length, allowing for easy attachment of accessories, fasteners, and components without drilling or welding. Their modular design makes them versatile for creating frames, workstations, automation systems, and countless other applications.
• Angle Aluminum channels. These L-shaped profiles feature two sides that meet at a 90-degree angle. Despite their straightforward design, angle aluminum channels provide excellent structural support and are used in framing, bracing, edge protection, and trim work.
• Architectural Aluminum channels. These extruded aluminum channels are designed with visual appeal as a primary consideration while maintaining structural integrity. Featuring clean lines, precise finishes, and often available with decorative surface treatments, architectural channels are widely specified in building facades, window framing, and interior design elements.
• Aluminum Slide Track channels. These specialized channels incorporate precision-engineered tracks that facilitate smooth linear motion of components. With low-friction surfaces and wear-resistant design, slide track aluminum channels are ideal for sliding doors, windows, display cases, and drawer systems.

Aluminum Channel Grades

Aluminum channel products are also available in several different grades, including 6061 and 6063.

6061 aluminum channel (also known as structural) is an aluminum grade used for all types of fabrication projects where lightweight and corrosion resistance are a priority, including braces, supports, and framework. Alloyed with silicon and magnesium, this grade is resistant to corrosion, stress, and cracking, but is not easy to bend or cold work.

6063 aluminum channel (also known as architectural aluminum trim channel) is an aluminum grade with sharp, right-angle inside and outside corners. It offers high tensile strength, high corrosion resistance and excellent formability. The 6063 grade is widely used for framework, brackets, and interior and exterior architectural trim because of its shiny finish.

Aluminum channel is available in many different sizes, lengths and wall thicknesses from Metal Supermarkets.
