HEA HEB 300 Structural Steel H Steel Beam S235J0 S355JR S355J0
HEA300 h section steel Applications: high-rise buildings, light industrial structures.
HEB300 structural h beam Applications: heavy industrial columns, long-span bridges, precision equipment bases.
HEA300 h shaped steel and HEB300 h beam structure differ mainly in flange/web thickness, resulting in different load capacities and applications, HEA300 h section beam is best suited for standard loads and cost-effectiveness, HEB300 steel h column is designed for heavy, high stability and earthquake-resistant scenarios.
Cross-Section & Weight

Mechanical Performance & Applications
| Property | HEA300 | HEB300 |
|---|---|---|
| Bending Resistance | Ideal for vertical bending (e.g., bridge beams). | Superior for combined bending and shear (e.g., heavy factory frames). |
| Shear Strength | Moderate, relying on web thickness. | Higher due to reinforced web. |
| Stability | Suited for long-span, low-lateral-force structures. | Enhanced seismic resistance for earthquake-prone areas. |
