This page provides data for area, weight per unit length, moment of intertia, Section Modulus, Radius of Gyration and centroid location for equal leg angle members.
wa = weight per foot of aluminum sections, lb ws = weight per foot of steel sections, lb A = area, in^2 I = moment of inertia, in^4 k = radius of gyration, in y = centroidal distance, in Z = section modulus, in^3 Size wa ws A I1-1 k1-1 Z1-1 y I3-3 k3-3 ------------------- ----- ----- ---- ----- ---- ---- ---- ------ ---- 1 x 1 x 1/8 0.28 0.80 0.23 0.02 0.30 0.03 0.30 0.008 0.19 1 x 1 x 1/4 0.53 1.49 0.44 0.04 0.29 0.05 3.34 0.016 0.19 1-1/2 x 1-1/2 x 1/8 0.44 1.23 0.36 0.07 0.45 0.07 0.41 0.031 0.29 1-1/2 x 1-1/2 x 1/4 0.83 2.34 0.69 0.14 0.44 0.13 0.46 0.057 0.29 2 x 2 x 1/8 0.59 1.65 0.49 0.18 0.61 0.13 0.53 0.08 0.40 2 x 2 x 1/4 1.14 3.19 0.94 0.34 0.60 0.24 0.58 0.14 0.39 2 x 2 x 3/8 1.65 4.70 1.37 0.47 0.59 0.35 0.63 0.20 0.39 2-1/2 x 2-1/2 x 1/4 1.45 4.1 1.19 0.69 0.76 0.39 0.71 0.29 0.49 2-1/2 x 2-1/2 x 3/8 2.11 5.9 1.74 0.98 0.75 0.56 0.76 0.41 0.48 3 x 3 x 1/4 1.73 4.9 1.43 1.18 0.91 0.54 0.82 0.49 0.58 3 x 3 x 3/8 2.55 7.2 2.10 1.70 0.90 0.80 0.87 0.70 0.58 3 x 3 x 1/2 3.32 9.4 2.74 2.16 0.89 1.04 0.92 0.91 0.58 3-1/2 x 3-1/2 x 1/4 2.05 4.9 1.69 1.93 1.07 0.76 0.94 0.80 0.69 3-1/2 x 3-1/2 x 3/8 3.01 7.2 2.49 2.79 1.06 1.11 1.00 1.15 0.68 3-1/2 x 3-1/2 x 1/2 3.94 11.1 3.25 3.56 1.05 1.45 1.05 1.49 0.68 4 x 4 x 1/4 2.35 6.6 1.94 2.94 1.23 1.00 1.07 1.21 0.79 4 x 4 x 3/8 3.46 9.8 2.86 4.26 1.22 1.48 1.12 1.75 0.78 4 x 4 x 1/2 4.54 12.8 3.75 5.46 1.21 1.93 1.17 2.26 0.78 4 x 4 x 5/8 5.58 15.7 4.61 6.56 1.19 2.36 1.22 2.76 0.77 6 x 6 x 3/8 5.27 14.9 4.35 14.85 1.85 3.38 1.60 6.07 1.18 6 x 6 x 1/2 6.95 19.6 5.74 19.38 1.84 4.46 1.66 7.92 1.17 6 x 6 x 5/8 8.59 24.2 7.10 23.64 1.82 5.51 1.71 9.70 1.17 6 x 6 x 3/4 10.20 28.7 8.43 27.64 1.81 6.52 1.76 11.43 1.16 ------------------- ----- ----- ---- ----- ---- ---- ---- ------ ----
