Hot-Rolled
H Beam
ISHB Sections
Wide-flange H Beam sections for industrial columns, multi-storey structures, warehouses, gantries, and heavy fabrication where axial load capacity, flange stability, and dimensional accuracy are non-negotiable.
H Beam ISHB — Up Close
Wide-flange H Beam sections with deeper flange stability, column-grade structural geometry, and mill-standard finish for heavy-duty applications.

0304What Is an
H Beam?
An H Beam — also designated ISHB (Indian Standard Heavy Beam) or Wide Flange Beam — is a hot-rolled structural steel section with an H-shaped cross-section. It consists of two wide flanges connected by a central web, with the flange width approximately equal to or close to the section depth. This near-square profile is what fundamentally separates H Beam from I Beam and makes it the preferred choice for column applications.
In the ISHB designation system, the number refers to the nominal depth in millimetres — so ISHB 300 is 300mm deep with flanges of approximately 300mm width. This near-equal proportion of depth and flange gives H Beams exceptional resistance to both axial compression and lateral buckling, the two dominant forces acting on structural columns.
H Beams are produced under IS:808 dimensional standards and typically conform to IS:2062 Grade A material specification. Primary mill supply from SAIL and RINL comes with full traceability through mill test certificates. H Beams can be welded, drilled, bolted, and flame-cut using standard fabrication equipment — and unlike concrete columns, they support longer clear spans with fewer intermediate supports, enabling open-plan industrial and commercial layouts.
H Beams are also manufactured in European (HEA/HEB/HEM) and American (W-section) standards. If your structural drawing specifies a section in those formats, confirm the equivalent ISHB size and weight with your structural engineer before ordering.
H Beam vs I Beam — Key Differences
The right section depends on how your structure loads it. Use this guide to specify correctly from the start — the wrong choice can compromise design efficiency and add unnecessary project cost.
Applications
- Wider flanges — near-equal depth and width allows better load distribution across both axes simultaneously
- Higher axial capacity — thicker section mass makes H Beam the default choice for columns carrying vertical compression
- Greater torsional resistance — wide flanges resist twisting under eccentric loads and lateral wind forces on columns
- Better for long-term durability — heavier cross-section suits large-scale projects where structural life and load headroom matter
- Open space design — steel columns need fewer intermediate supports than concrete, enabling wider spans and open-plan layouts
Applications
- Narrow flanges — web depth significantly greater than flange width concentrates material where bending stress is highest
- Higher bending efficiency — deeper web relative to flange gives superior moment of inertia for horizontal span loading
- Lighter sections available — ISMB starts at 8.9 kg/m vs ISHB minimum at around 23 kg/m, making I Beam more economical for lintels and light frames
- More economical for lightly loaded beams — for spans where axial compression is not the dominant force, I Beam delivers adequate performance at lower cost
- Standard for rafters and purlins — horizontal roof members and crane girder beams use ISMB as the default section
| Parameter | H Beam (ISHB) | I Beam (ISMB) |
|---|---|---|
| Cross-section shape | H-shape — flanges ≈ depth | I-shape — depth > flange width |
| Primary loading direction | Axial (compression) + bending | Bending (horizontal spans) |
| Best structural role | Columns, gantry legs, heavy portals | Beams, rafters, lintels, mezzanine |
| Flange width vs depth | Approximately equal | Flange much narrower than depth |
| Torsional stiffness | High — suitable for columns | Lower — not ideal for column use |
| Weight range (IS:808) | 23–302 kg/m | 8.9–123 kg/m |
| HSN Code | 7216 | 7216 |
| Standard | IS:808 / IS:2062 | IS:808 / IS:2062 |
