HEA 100 vs HEB 100
- HEA 100 is 18 % lighter than HEB 100 (16.7 vs 20.4 kg/m).
- HEB 100 has 29 % higher strong-axis stiffness Iy.
- HEB 100 has 25 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEB 100 has 26 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, HEB 100 is the more efficient bending section (Iy/G: 22 vs 21 cm⁴ per kg/m).
