An I-beam, also known as H-beam is a beam with an I or H-shaped cross-section. These beams are widely used in construction activities.
Based on their flanges, they can be:
In India, I-beams are designated as:
Beams are designated as per respective abbreviated reference followed by the depth of section such as for example ISMB 450, where 450 is the depth of section in millimeters (mm). The dimensions of these beams are classified as per 'Burea of Indian Standards'.
We deal in I Beams of following standard sizes:
- Squared Beams (W cross-section)
- Tapered Beams (S cross-section)
In India, I-beams are designated as:
- ISMB - Indian Standard Medium Weight Beam,
- ISJB : Indian Standard Junior Beams,
- ISLB : Indian Standard Light Weight Beams,
- ISWB : Indian Standard Wide Flange Beams.
Pros:
The I-shaped section is a very efficient form for carrying both bending loads and shear loads. The center piece resists shear forces while the flanges resist most of the bending moment experienced by the beam.Cons:
The cross-section has a reduced capacity in the transverse direction, and is also inefficient in carrying torsion, for which hollow structural sections are often preferred.

We deal in I Beams of following standard sizes:
- ISMB 80,
- ISMB 100,
- ISMB 120,
- ISMB 140
