Frequently Asked Questions
What is the weight of a W6X25 beam? 25 lb/ft (37 kg/m). A 40-ft length weighs approximately 1,000 lbs.
What is the section modulus of W6X25? Sx = 16.7 in³ (strong axis) and Sy = 5.6 in³ (weak axis). The plastic section modulus Zx = 18.9 in³ and Zy = 8.6 in³.
What steel grade is standard for W6X25? 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 W6X25? Ix = 53.4 in⁴ about the strong axis and Iy = 17.1 in⁴ about the weak axis. The radius of gyration is rx = 2.70 in and ry = 1.52 in.
