This page provides data for area, weight per unit length, moment of intertia, Section Modulus and Radius of Gyration for misc beam sections.
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 --- --- ----- ------ ------ ------- ----- ------ ------ ----- ------ M6 6 6 20 5.89 39.0 2.57 13.0 11.6 1.40 3.90 M4 4 4 13.0 3.81 10.5 1.66 5.24 3.36 .939 1.71 --- --- ----- ------ ------ ------- ----- ------ ------ ----- ------
