How to Choose the Right Size and Shape of Aluminum Angle Extrusions

Aluminum angle extrusions are a versatile and durable building material that can be used in a wide variety of applications. They are commonly used as structural framing members, window and door frames, and various other components. Selecting the right size and shape of aluminum angle extrusions is essential for ensuring the strength, functionality, and aesthetics of your project. This article provides a detailed guide to help you make the right choices when selecting aluminum angle extrusions.

Consider the Application

The first step in choosing the right aluminum angle extrusions is to consider the intended application. The size and shape of the extrusions will depend on the loads they will be required to bear, the environmental conditions they will be exposed to, and the desired appearance of the finished product. For example, extrusions used in structural applications will require different properties than those used for decorative purposes.

Determine the Size

The size of the aluminum angle extrusions refers to the length, width, and thickness of the extrusions. The length and width will determine the overall dimensions of the component, while the thickness will determine its strength and rigidity. The thickness of the extrusions will also affect the weight and cost of the finished product.

Choose the Shape

Aluminum angle extrusions come in various shapes, including equal angles, unequal angles, and T-slots. Equal angles have equal length legs, while unequal angles have legs of different lengths. T-slots are extrusions with a T-shaped cross-section that allows for the insertion of fasteners. The shape of the extrusions will depend on the specific requirements of the application.

Consider the Material

Aluminum angle extrusions are typically made from 6061-T6 aluminum alloy, which is strong, durable, and corrosion-resistant. However, other aluminum alloys may be available depending on the specific requirements of the application. For example, 6063-T5 aluminum alloy is more resistant to corrosion than 6061-T6, while 7075-T6 aluminum alloy is stronger but more expensive.

Check the Finish

Aluminum angle extrusions can be supplied with different finishes, including mill finish, anodized finish, and powder-coated finish. Mill finish is the natural finish of the aluminum, while anodized finish provides a protective oxide layer that increases corrosion resistance. Powder-coated finish is a durable and decorative finish that is available in a wide range of colors.

Conclusion

Selecting the right size and shape of aluminum angle extrusions is essential for ensuring the successful completion of your project. By considering the factors discussed in this article, you can make informed decisions that will result in a finished product that meets your specific requirements. If you are still unsure about the best choice of aluminum angle extrusions for your project, it is always a good idea to consult with an experienced aluminum supplier or fabricator.
