Steel Angle Sizes (Imperial)

Steel angle sections are commonly used for framing, brackets, reinforcement, and structural applications. Equal-leg angles have two legs of the same length, while unequal-leg angles have different leg lengths for improved load distribution in one direction. The table below lists imperial angle dimensions in inches, along with mass per foot, cross-sectional area, thickness, and root radius. These properties are typically referenced when selecting members for strength, stiffness, and fabrication suitability in steel construction.

Dimensions and properties in US customary units: leg lengths a (and b for unequal), thickness t, root radius rroot, mass per foot, and section area.
