Different Types of Extruded Aluminum Channels

weiye 0

Extruded aluminum channels are among the most widely used construction materials. Their versatility means they can be shaped, configured, and adapted to fit many structural applications. 

Aluminum channels are commonly used in construction and industrial projects where lightweight strength, corrosion resistance, and customizability are important. Applications include framing, reinforcement, LED light applications, and mounting fixtures. Below is a look at the different types of extruded aluminum channels available today.



1. Angle 


Angle extruded aluminum channels have a profile that forms a right angle. The right-angle trim can be squared (sharp angle) or rounded (smooth angle). They are the simplest forms of aluminum channels and have a variety of applications, including finishing and trims. 

You can commonly find extruded angle channels on handrails, edges of roofing, and building corners. Various aluminum alloys are used to construct the channels, which can come in different types of finishes.


2. U-Shaped


U-shaped aluminum channels are among the most commonly utilized type. They have a simple design featuring two vertical parallel legs (flanges) that are perpendicular to a horizontal base or web.  This design makes U-shaped channels suited for a wide range of applications, including framing, support, and edging.

The thickness of the walls varies depending on the use cases. U-shaped aluminum channels are commonly used in industrial applications to support equipment, as well as in construction settings to support doors, panels, and windows.


3. C-Shape 


C-Shape extruded aluminum channels have a simple design comprising a “C” shaped profile. There are some variations in the design of the flanges and corners. In many cases, one flange is usually longer. This design gives the C-shape a flatter profile for low-profile applications. 

Just like Angle types, the corners on the inside of the channels may be squared or rounded. Extruded C-shape aluminum channels are commonly used for framing and supporting wood panels. They can also be used for store fixtures and aesthetic additions.


4. T-Slot 


An extruded T-slot aluminum channel features several slots where you can fit T-shaped attachments. The slot allows you to slide the attachments up or down. This type of aluminum channel facilitates the construction of elaborate configurations that do not require welding or riveting. 

You can easily connect T-slot channels via mounting bolts. This helps save construction costs since there is no need for welding or clamming.


5. H-shape 


H-shape aluminum channels consist of two long flanges connected by a web. The web may be located at the midpoint of the flanges or slightly above/below this point. The profile resembles the letter “H.” These channels can feature battens for enhancing hold.

H-shape channels are highly stable and are commonly used in construction or decorative projects. They are well suited for trim, railings, and doorframes. Some types of H-shape have a profile resembling the lowercase “h.” This type is mainly used for ceiling support.


6. Z Shaped 


Z-shaped aluminum channels feature a web with flanges that extend in opposite directions. The profile resembles the letter “Z.” There are several varieties, such as bar Z and clips. 

Bar Z aluminum channels feature the usual Z profile, while clips feature a small web. Extruded Z-shaped channels are used for unique roofing constructions. They serve as roof flashing, ridge caps, and panel receivers.


7. Hat Shape 


Hat shape extruded aluminum channels are also referred to as furring channels. They have a unique design with two parallel flanges used to fur out ceilings or ceilings. Furring a method of leveling uneven ceilings and walls. 

Its profile resembles a hat. Hat-shape types are exceptionally strong, durable, and resistant to corrosion. This makes this type of aluminum channel suitable for the furring process.


8. F-Shape 


An F-shape aluminum channel is similar to a U-shape but features an extended web or base that does not have a leg (flange). The profile resembles the letter “F.” In this type of channel, the distance between the legs and the length of the extended web may vary depending on the intended application. Extruded F-shape aluminum channels are typically used for support and mounting.


Overall, extruded aluminum channels are a reliable, versatile, and adaptable solution for construction and industrial applications. They offer lightweight strength, durability, and a variety of finishing options.
