IPE 240 vs HEA 240
- IPE 240 is 49 % lighter than HEA 240 (30.7 vs 60.3 kg/m).
- HEA 240 has 99 % higher strong-axis stiffness Iy.
- HEA 240 has 9.8× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEA 240 has 103 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, both are similarly efficient in bending (Iy/G ≈ 128 cm⁴ per kg/m).
