This page provides data for area, weight per unit length, moment of intertia, Section Modulus and Radius of Gyration for wide flange members.
D = Section depth, in wf = Flange width, in ws = weight per foot of steel sections, lb per foot A = area, in^2 I = moment of inertia, in^4 k = radius of gyration, in Z = section modulus, in^3 S D wf ws A I1-1 k1-1 Z1-1 I2-2 k2-2 Z2-2 --- ------ ------ ----- ----- ------ ----- ------ ------- ----- ------ W36 36-3/4 16-5/8 300 88.3 20300 15.2 1110 1300 3.83 156 W36 36-3/4 12-1/8 210 61.8 13200 14.6 719 411 2.58 67.5 W33 34-1/8 15-7/8 241 70.9 14200 14.1 829 932 3.63 118 W30 31 15-1/8 211 62.0 10300 12.9 663 757 3.49 100 W30 30-1/4 10-1/2 132 38.9 5770 12.2 380 196 2.25 37.2 W27 27-3/4 14-1/8 178 52.3 6990 11.6 502 555 3.26 78.8 W27 27-1/4 10-1/8 114 33.5 4090 11.0 299 159 2.18 31.5 W24 25 13 162 47.7 5170 10.4 414 443 3.05 68.4 W24 24-1/4 9-1/8 94 27.7 2700 9.87 222 109 1.98 24.0 W24 23-3/4 7 62 18.2 1550 9.23 131 34.5 1.38 9.80 W21 22 12-1/2 147 43.2 3630 9.17 329 376 2.95 60.1 W21 21-5/8 8-3/8 93 27.3 2070 8.70 192 92.9 1.84 22.1 W21 21 6-1/2 57 16.7 1170 8.36 111 30.6 1.35 9.35 W18 19 11-1/4 119 35.1 2190 7.90 231 253 2.69 44.9 W18 18-1/2 7-5/8 71 20.8 1170 7.50 127 60.3 1.70 15.8 W18 18 6 46 13.5 712 7.25 78.8 22.5 1.29 7.43 W16 17 10-3/8 100 29.4 1490 7.10 175 186 2.51 35.7 W16 16-3/8 7-1/8 57 16.8 758 6.72 92.2 43.1 1.60 12.1 W16 15-7/8 5-1/2 31 9.12 375 6.41 47.2 12.4 1.17 4.49 W14 22-3/8 17-7/8 730 215 14300 8.17 1280 4720 4.69 527 W14 14-5/8 14-3/4 132 38.8 1530 6.28 209 548 3.76 74.5 W14 14-1/2 10-1/8 82 24.1 882 6.05 123 148 2.48 29.3 W14 13-7/8 8 53 15.6 541 5.89 77.8 57.7 1.92 14.3 W14 14-1/8 6-3/4 38 11.2 385 5.87 54.6 26.7 1.55 7.88 W14 13-7/8 5 26 7.69 245 5.65 35.3 8.91 1.08 3.54 W12 14-3/8 12-5/8 190 55.8 1890 5.82 263 589 3.25 93.0 W12 12-1/4 10 58 17.0 475 5.28 78 107 2.51 21.4 W12 12-1/4 8-1/8 50 14.7 394 5.18 64.7 56.3 1.96 13.9 W12 12-1/2 6-1/2 35 10.3 285 5.25 45.6 24.5 1.54 7.47 W12 12-1/4 4 22 6.48 156 4.91 25.4 4.66 .847 2.31 W10 11-3/8 10-3/8 112 32.9 716 4.66 126 236 2.68 45.3 W10 10-1/8 8 45 13.3 248 4.32 49.1 53.4 2.01 13.3 W10 10-1/2 5-3/4 30 8.84 170 4.38 32.4 16.7 1.37 5.75 W10 10-1/4 4 19 5.62 96.3 4.14 18.8 4.29 .874 2.14 W8 9 8-1/4 67 19.7 272 3.72 60.4 88.6 2.12 21.4 W8 8 6-1/2 28 8.25 98.0 3.45 24.3 21.7 1.62 6.63 W8 8-1/4 5-1/4 21 6.16 75.3 3.49 18.2 9.77 1.26 3.71 W8 8-1/8 4 15 4.44 48.0 3.29 11.8 3.41 .876 1.70 W6 6-3/8 6-1/8 25 7.34 53.4 2.70 16.7 17.1 1.52 5.61 W6 6-1/4 4 16 4.74 32.1 2.60 10.2 4.43 .966 2.20 --- ------ ------ ---- ------ ------- ----- ------ ------ ----- ------
