Right-angled supports, fabricated from a lightweight, corrosion-resistant metal, are widely available through a major home improvement retailer. These supports serve to join or reinforce structures at a 90-degree angle. For instance, these can be used to secure shelving to a wall or connect pieces of lumber in a frame.
The utility of these supports lies in their strength-to-weight ratio and resistance to environmental degradation. This makes them suitable for both indoor and outdoor applications. Historically, similar supports were crafted from heavier materials, such as steel, but aluminum offers a lighter, more manageable alternative without significantly compromising structural integrity. This has facilitated their widespread adoption in DIY projects and professional construction.
