IPE 160 vs HEA 160
- IPE 160 is 48 % lighter than HEA 160 (15.8 vs 30.4 kg/m).
- HEA 160 has 92 % higher strong-axis stiffness Iy.
- HEA 160 has 9.0× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEA 160 has 98 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, both are similarly efficient in bending (Iy/G ≈ 55 cm⁴ per kg/m).
