Our I-Beams are designed for critical load-bearing applications where structural integrity, dimensional accuracy, and long-term performance are essential. All I-Beams supplied by Sarthak Ispat comply with IS 808 and IS 2062 standards and are suitable for both domestic and export EPC requirements.
What is an I-Beam?
An I-Beam is a hot-rolled structural steel section characterized by its distinct “I” shaped cross-section, consisting of two horizontal flanges connected by a vertical web.
This geometry allows the beam to efficiently resist bending moments, shear forces, and axial loads while minimizing steel consumption. I-Beams are therefore one of the most widely used structural members in modern construction and heavy engineering.
Structural Engineering Principles of I-Beams
The design of an I-Beam places material where stresses are highest. Flanges resist bending stresses, while the web transfers shear forces. This results in high strength-to-weight efficiency and predictable structural behavior.
- Excellent bending resistance
- Efficient shear force transfer
- Reduced self-weight compared to solid sections
- Reliable performance under static and dynamic loads
Types of Structural Steel I-Beams
Depending on load requirements and structural design, I-Beams are classified into the following categories:
- ISMB – Indian Standard Medium Weight Beam
- ISWB – Indian Standard Wide Flange Beam
- ISHB – Indian Standard Heavy Beam
- WPB – Wide Plate Beam (used in heavy and export projects)
