W8x28 W8x31 W8x35 W8x40 h beam ASTM A36/A572GR50/A992
| model | Cross-sectional dimensions (h× w × t× f, mm) | Theoretical weight(kg/m) | Cross-sectional area(cm²) |
|---|---|---|---|
| W8×28 | 205×166×7.2×11.8 | 41.7 | 53.1 |
| W8×31 | 203×203×7.2×11 | 46.1 | 58.6 |
| W8×35 | 206×204×7.9×12.6 | 52.0 | 66.5 |
| W8×40 | 210×205×9.1×14.2 | 59.0 | 75.6 |
h shaped steel web and flange thickness
W8×40 has the thickest web (9.1mm) and the thickest flange (14.2mm), and has the strongest shear and bending resistance; W8×28 has thinner web and flange (7.2mm/11.8mm), which is lightweight but has lower load capacity.
h beam profile weight and moment of inertia
The weight ranges from 41.7kg/m (W8×28) to 59kg/m (W8×40), and the section moment of inertia increases significantly with the increase in size, which is suitable for larger spans or heavy load scenarios.
h steel profile structural characteristics comparison
W8×28: narrow flange design (width 166mm), light weight, suitable for secondary beams or auxiliary supports with medium loads.
W8×31: square section (203×203mm), balanced thickness of flange and web, suitable for beam-column structures of medium-span industrial plants.
W8×35: Wide flange (204mm) and thickened flange (12.6mm), high bending stiffness, used for main beams or columns with high stability requirements.
W8×40: The web thickness is increased to 9.1mm, with excellent shear resistance, suitable for bridge main beams or heavy equipment support platforms.
Structural steel h beam application scenario comparison
| model | Applicable scenarios |
|---|---|
| W8×28 | Medium load building secondary beams, light warehouse supports |
| W8×31 | Industrial plant medium span beams and columns, multi-story building frames |
| W8×35 | Main beams of large factory buildings and supporting structures of medium-sized bridges |
| W8×40 | Heavy-load bridge beams, heavy industrial equipment bases, large-span stadium roofs |
