Equal Angles - 30x30x4

Steel equal angles are L-shaped structural steel bars where the two horizontal and vertical legs are exactly the same length. Often called "L-sections" or "angle irons," they are manufactured with a sharp 90-degree bend that gives them excellent rigidity and resistance to bending. Because both sides match, they provide equal strength in both directions, making them incredibly versatile for bracing, framing, and supporting loads. These common shapes are widely used for making shelf brackets, roof trusses, gate frames, and reinforcing corners in everyday construction projects.
