IPE 300 vs HEA 300
- IPE 300 is 52 % lighter than HEA 300 (42.2 vs 88.3 kg/m).
- HEA 300 has 2.2× higher strong-axis stiffness Iy.
- HEA 300 has 10.5× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEA 300 has 120 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, HEA 300 is the more efficient bending section (Iy/G: 207 vs 198 cm⁴ per kg/m).
