IPE 240 vs HEB 240
- IPE 240 is 63 % lighter than HEB 240 (30.7 vs 83.2 kg/m).
- HEB 240 has 2.9× higher strong-axis stiffness Iy.
- HEB 240 has 13.8× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEB 240 has 187 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, HEB 240 is the more efficient bending section (Iy/G: 135 vs 127 cm⁴ per kg/m).
