H Beam vs I Beam: Understanding the Key Differences
H beams and I beams are both essential structural sections with important differences in geometry, load-bearing, and applications.
Geometric Differences
I Beam: Narrower flanges that taper inward, web relatively thick vs. flange width, lower weight per meter.
H Beam: Wider flanges with parallel inner surfaces, web thinner relative to flange width, higher weight per meter. Classified as HW (wide), HM (medium), HN (narrow), HP (pile).
Section Properties
| Property | H Beam | I Beam |
|---|---|---|
| Flange Width | Wide (near depth) | Narrow |
| Inner Surface | Parallel | Tapered |
| Weak Axis Modulus | Much higher | Low |
| Connection Ease | Easier (flat flange) | Harder |
Application Guide
| Application | Preferred | Reason |
|---|---|---|
| Building columns | H Beam | Biaxial loading |
| Long-span beams | H Beam | High moment capacity |
| Light purlins | I Beam | Light loads, cost-effective |
| Pile foundations | H Beam (HP) | Designed for driving |
Can H Beam Replace I Beam?
In most cases, yes — if weight increase is acceptable. Modern construction increasingly favors H beams for versatility and connection advantages.
