Frequently Asked Questions
What is the weight of a W6X12 beam? 12 lb/ft (18 kg/m). A 40-ft length weighs approximately 480 lbs.
What is the section modulus of W6X12? Sx = 7.3 in³ (strong axis) and Sy = 1.5 in³ (weak axis). The plastic section modulus Zx = 8.3 in³ and Zy = 2.3 in³.
What steel grade is standard for W6X12? Typically ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) for W-shapes. Also available in A572 Grade 50 or A36. Verify with mill certificate.
What is the moment of inertia of W6X12? Ix = 22.1 in⁴ about the strong axis and Iy = 3.0 in⁴ about the weak axis. The radius of gyration is rx = 2.49 in and ry = 0.92 in.
