IPE 220 vs HEA 220
- IPE 220 is 48 % lighter than HEA 220 (26.2 vs 50.5 kg/m).
- HEA 220 has 95 % higher strong-axis stiffness Iy.
- HEA 220 has 9.5× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEA 220 has 99 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, both are similarly efficient in bending (Iy/G ≈ 106 cm⁴ per kg/m).
