L3-1/2x3-1/2x1/2 (L3.5x3.5x.5) – L Shapes - Equal Leg Angles

L3-1/2x3-1/2x1/2 is an equal-leg angle with 3.5 in (89 mm) legs, 1/2 in (13 mm) thick, weighing 11.1 lb/ft (16.5 kg/m).

Equal leg angles are one of the simplest and most versatile structural sections, with two legs of the same size meeting at a right angle. Their simplicity is their strength: angles are inexpensive, easy to cut, drill, bolt and weld, and useful almost anywhere a structure needs bracing, a connection element or a lightweight framing member. Common applications include diagonal bracing, truss web members, framing clips and connection angles, ladder and frame components, and general-purpose fabrication work where a full I-shaped or channel section would be unnecessary.
