What are the typical leg length ranges for A992 angle steel?

A992 angle steel (equal-leg and unequal-leg) has standard leg lengths from 1.5 inches (38.1 mm) to 8 inches (203.2 mm). Equal-leg angles (e.g., L3x3x0.375) have identical leg lengths, while unequal-leg angles (e.g., L6x4x0.5) have differing lengths. Common equal-leg sizes include L2x2x0.25, L4x4x0.5, and L6x6x0.75; typical unequal-leg sizes include L5x3x0.5 and L8x4x0.625. Leg length is measured from the outer edge of one leg to the end of the other, a critical dimension for load distribution. ASTM A992/A992M-22 specifies leg length tolerances of ±0.06 inches (1.52 mm) for legs ≤4 inches and ±0.12 inches (3.05 mm) for legs >4 inches, ensuring consistency across batches and compatibility with prefabricated components.
