A Fabricator’s Guide to Metal Angles

Metal angles are one of the most versatile and widely used structural elements in construction and engineering. These L-shaped metal pieces are crucial for providing support and stability in various structures, from buildings and bridges to machinery and furniture. If you’re doing metal work soon, it’s best to learn the specifics of metal angles made from aluminum, bronze, and steel, to know their properties, applications, and the advantages and disadvantages of each type.

Types of Metal Angles

Metal angles come in various materials, each offering unique characteristics that make them suitable for different applications. The most common types of metal angles are aluminum, bronze, and steel.

Aluminum Angles

Aluminum is known for its lightweight nature and excellent corrosion resistance. It is non-magnetic, making it ideal for applications where magnetic interference is a concern. Additionally, aluminum is highly malleable, allowing it to be easily formed and fabricated into various shapes and sizes.

Uses and Applications of Metal Angles

Metal angles are incredibly versatile and serve a wide range of applications beyond large-scale industrial projects. Smaller, specialized end-users such as fabricators, artists, hobbyists, machine shops, and do-it-yourself (DIY) practitioners also find metal angles indispensable for various creative and functional projects. Here are some of the unique uses and applications of metal angles in these specialized fields:


Fabricators, who often work on custom metal projects, rely heavily on metal angles for their structural integrity and ease of use. Metal angles provide the necessary strength and stability for a variety of custom fabrications, including:

  • Custom Shelving Units: Metal angles are perfect for creating sturdy, custom-sized shelving units for commercial and residential use. Their strength ensures that the shelves can support heavy loads.
  • Frames and Supports: Fabricators use metal angles to construct frames and supports for machinery, equipment, and other structures. The L-shape of the angle iron provides excellent stability.
  • Staircases and Railings: Custom staircases and railings made from metal angles offer both strength and a modern aesthetic, suitable for both indoor and outdoor applications.


Artists and sculptors often incorporate metal angles into their works due to their durability and flexibility. Metal angles can be used to create:

  • Sculptures: The rigidity of metal angles makes them ideal for creating large, stable sculptures that can withstand various weather conditions when displayed outdoors.
  • Mixed Media Art: Artists can combine metal angles with other materials like wood, glass, and stone to create unique mixed media pieces that stand out in galleries and exhibitions.
  • Functional Art: Metal angles are used in the creation of functional art pieces such as custom furniture, light fixtures, and other decorative items that blend form and function.

Hobbyists and DIY Practitioners

For hobbyists and DIY enthusiasts, metal angles are a go-to material for a wide range of home improvement and creative projects. Their versatility allows for numerous applications, including:

  • Home Decor: Metal angles can be used to create custom furniture, picture frames, shelves, and other home decor items. Their clean lines and industrial look add a modern touch to any space.
  • Garden Projects: DIY gardeners use metal angles to build plant stands, trellises, and raised garden beds. The durability of metal ensures these structures withstand outdoor elements.
  • Workshop Tools: Hobbyists often use metal angles to construct custom jigs, workbenches, and tool racks, enhancing the functionality of their workshops.

Machine Shops

Machine shops, which specialize in the machining and assembly of metal parts, utilize metal angles for their precision and reliability. Common applications include:

  • Equipment Mounts: Metal angles are used to create mounts and brackets for various types of machinery and equipment, ensuring they remain securely in place.
  • Custom Fixtures: Custom fixtures and jigs made from metal angles help streamline machining processes, providing stable and precise setups for complex tasks.
  • Structural Components: Metal angles are essential for building structural components of machines and devices, offering strength and durability needed for heavy-duty applications.
