IPE 300 vs HEB 300
- IPE 300 is 64 % lighter than HEB 300 (42.2 vs 117.0 kg/m).
- HEB 300 has 3.0× higher strong-axis stiffness Iy.
- HEB 300 has 14.2× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEB 300 has 197 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, HEB 300 is the more efficient bending section (Iy/G: 215 vs 198 cm⁴ per kg/m).
