h beam
H-beams, also known as W-beams because of their wide flanges, are significantly different from I-beams. The flanges of H-beams are equal and parallel, making welding easier than the angled flanges of I-beams. The cross-sectional properties of H-beams are superior to those of conventional I-beams, channels and angles. The name of this structural member is derived from the letter "H", reflecting its cross-sectional shape.
i beam
I-beams are characterized by an "I" shape with the inner surfaces of the top and bottom flanges sloped, which allows the use of thicker I-beams, but this structural design can limit torsional resistance.
| Feature | H-Beam | I-Beam |
| Cross-Section Shape | Wide flanges, nearly square cross-section resembling the letter "H." | Narrow flanges, tapered edges resembling the letter "I." |
| Web Thickness | Thicker web, providing greater resistance to shear forces. | Thinner web, making it lighter but less resistant to shear forces. |
| Flange Width | Wider flanges, offering better load distribution and bending resistance. | Narrower flanges, suitable for vertical loads but less effective for bending. |
| Strength-to-Weight Ratio | Higher strength-to-weight ratio, ideal for heavy-duty applications. | Lower strength-to-weight ratio, better for lighter loads. |
| Load-Bearing Capacity | Superior load-bearing capacity, suitable for both vertical and horizontal loads. | Good for vertical loads but less effective for horizontal loads. |
| Resistance to Buckling | More resistant to buckling due to wider flanges and thicker web. | Less resistant to buckling, especially under heavy loads. |
| Torsional Strength | Higher torsional strength, suitable for applications with twisting forces (e.g., bridges, heavy platforms). | Lower torsional strength, not ideal for twisting forces. |
| Surface Area | Larger surface area, providing better resistance to compression and bending. | Smaller surface area, weaker resistance to compression and bending. |
| Manufacturing Process | Typically fabricated by welding three steel plates, resulting in higher strength. | Rolled or hot-rolled as a single piece, simpler process but lower strength. |
| Span Length | Can span longer distances (up to 330 feet) without additional support. | Typically used for shorter spans (up to 100 feet), may require additional support. |
| Applications | Suitable for high-rise buildings, bridges, industrial platforms, and heavy structures. | Commonly used in residential construction, elevator frames, and trailer supports. |
| Cost | More cost-effective for large-scale projects due to material efficiency. | May be more economical for smaller projects with lighter loads. |
