W40x327 W40x331 Hot Rolled H Beam Steel Column

W40×327 and W40×331 h-shaped beams belong to the W40 series of American standard H-shaped steel. The "W40" in the name means that the nominal depth of the section is about 40 inches, and the number (such as 327) represents the weight per foot (unit: pounds/foot).

Section height (d): about 40.79 inches (about 1036.1 mm)
Flange width (bf): about 12.20 inches (about 309.9 mm)
Web thickness (tw): about 1.07 inches (about 27.2 mm)
Flange thickness (tf): about 1.93 inches (about 49.0 mm)
Sectional area: about 96.2 square inches (about 62064.5 mm²)
Moment of inertia (Ix): about 17,700 inches⁴ (about 7366×10⁶ mm⁴, horizontal axis)
Moment of inertia (Iy): about 682 inches⁴ (about 283.7×10⁶ mm⁴, vertical axis)
Weight per meter: about 486.61 kg/m
Weight per foot: 327 pounds

Sectional height (d): about 40.87 inches (about 1038.1 mm)
Flange width (bf): about 12.22 inches (about 310.4 mm)
Web thickness (tw): about 1.09 inches (about 27.7 mm)
Flange thickness (tf): about 1.95 inches (about 49.5 mm)
Sectional area: about 97.4 square inches (about 62838.7 mm²)
Moment of inertia (Ix): about 18,000 inches⁴ (about 7490×10⁶ mm⁴, horizontal axis)
Moment of inertia (Iy): about 696 inches⁴ (about 289.6×10⁶ mm⁴, vertical axis)
Weight per meter: about 492.56 kg/m
Weight per foot: 331 pounds

1. The cross-sectional height of both is similar (about 40.8 inches), the web and flange of W40×331 are slightly thicker, and the cross-sectional area and moment of inertia are slightly larger.
2. The moment of inertia (Ix) is higher, indicating strong bending resistance and suitable for long-span beams.
3. The flange width (about 12.2 inches) provides good resistance to lateral instability.
4. Common lengths are 6 meters, 9 meters, 12 meters or customized on demand.
