Extruded aluminum angle, a versatile material frequently specified in architectural designs, exhibits a range of sizes impacting structural performance. Engineers often select specific 6061 aluminum alloy grades for extruded aluminum angle, due to its optimal strength-to-weight ratio in applications such as framework construction. The United States, with its advanced manufacturing sector, represents a significant source for various extruded aluminum angle profiles. Determining the right supplier often involves comparing prices and lead times from distributors like OnlineMetals, who offer a variety of sizes and finishes.
Understanding Extruded Aluminum Angle: A Comprehensive Guide
Extruded aluminum angle is a versatile and widely used material in various industries and DIY projects. Its inherent strength-to-weight ratio, corrosion resistance, and ease of fabrication make it a popular choice. This guide delves into the different sizes, common uses, and where to procure this essential component.
What is Extruded Aluminum Angle?
Essentially, it’s aluminum that has been forced through a die to create a specific L-shaped cross-section. The "extruded" part refers to the manufacturing process. This process allows for precise dimensions and the creation of complex shapes that would be difficult or impossible to achieve through other methods. The resulting angle provides structural support, edge protection, or a clean, finished look.
Decoding the Sizes: Dimensions and Terminology
When discussing sizes, there are key dimensions to understand:
- Leg Lengths: These refer to the lengths of the two sides that form the right angle. They can be equal (e.g., 1" x 1") or unequal (e.g., 2" x 1").
- Thickness: This is the thickness of the aluminum material itself. It’s crucial for determining the load-bearing capacity and overall strength of the angle.
Understanding how these dimensions are typically presented is key. You’ll often see sizes described as "Leg Length x Leg Length x Thickness." For instance, "2" x 2" x 1/8"" indicates an angle with two-inch legs and a thickness of one-eighth of an inch.
Common sizes range from fractional inches suitable for light-duty applications to several inches, used for more demanding structural purposes.
Common Uses of Extruded Aluminum Angle
The versatility of extruded aluminum angle stems from its adaptable properties. Here are some common applications:
- Construction: Framing for windows, doors, and walls; reinforcement of structural elements.
- Manufacturing: Machine guards, equipment frames, and jigs.
- Transportation: Trailer construction, truck bed protection, and securing cargo.
- DIY Projects: Shelving, brackets, edge protection, and decorative trim.
- Marine: Boat building and repair, where corrosion resistance is paramount.
The specific size and thickness chosen will depend on the application and the load it needs to support. Lighter angles are suitable for decorative purposes and edge protection, while thicker angles are required for load-bearing applications.
Advantages of Using Extruded Aluminum Angle
Several factors contribute to its widespread adoption:
- Lightweight Strength: Aluminum offers a high strength-to-weight ratio, making it easy to handle and install without compromising structural integrity.
- Corrosion Resistance: Naturally resistant to corrosion, especially when anodized or coated, making it suitable for outdoor and marine environments.
- Ease of Fabrication: It can be easily cut, drilled, welded, and machined, allowing for customization to specific project requirements.
- Recyclability: Aluminum is highly recyclable, making it an environmentally friendly material choice.
- Aesthetic Appeal: Available in various finishes (e.g., mill finish, anodized, painted), offering aesthetic flexibility.
Where to Buy Extruded Aluminum Angle
Sourcing extruded aluminum angle involves considering factors like quantity, specific size requirements, and desired finish. Common sources include:
- Metal Suppliers: These companies specialize in various metal products, including extruded aluminum. They often offer a wide range of sizes, thicknesses, and finishes.
- Hardware Stores: Larger hardware stores typically stock a selection of common sizes and thicknesses. This is a convenient option for smaller projects.
- Online Retailers: Numerous online retailers offer extruded aluminum angle, providing a wide selection and the convenience of online ordering.
- Specialty Extruders: Companies specializing in aluminum extrusion can often create custom sizes and shapes to meet specific project needs.
Consider the following factors when selecting a supplier:
