A36/A572GR50/A992 Steel Wide Flange H Beam W10x12 W10x15 W10x17
Web and flange thickness: W10×17 h profile steel has the thickest web (7.7mm) and the thickest flange (11.1mm), and has the strongest shear and bending resistance; W10×12 has thinner web and flange (6.1mm/8.7mm) and is lighter.
Flange width: W10×17 h beam structure has the largest flange width (105mm), which is wider than W10×12 (101mm) and W10×15 (102mm) and has higher stability.
h shaped beam core parameter comparison
| model | Cross-section size(H×B×t₁×t₂,mm) | Theoretical weight(kg/m) | Cross-sectional area(cm²) |
|---|---|---|---|
| W10×12 | 254×101×6.1×8.7 | 18 | 22.9 |
| W10×15 | 254×102×7.1×10.2 | 22.5 | 28.7 |
| W10×17 | 257×105×7.7×11.1 | 25.3 | 32.3 |
h section beam application scenario comparison
| model | Advantageous scenarios | limitation |
|---|---|---|
| W10×12 | Lightweight structures (equipment brackets, temporary supports), focusing on lightweight and economy. | The load-bearing capacity is low and is not suitable for heavy load or large span scenarios. |
| W10×15 | Medium span factory secondary beams and small bridge supports balance lightweight and load-bearing requirements. | The shear resistance is weaker than W10×17, so be careful in heavy-load scenarios. |
| W10×17 | Main beams of industrial buildings and bases of medium-sized equipment, where high bending stiffness and shear resistance are required | The cost is relatively high (25.3kg/m), and it is not suitable for lightweight projects. |
