What it is
The top and bottom flanges carry most of the bending, while the thin web joins them. I-beams (also called ISMB in India) are used in steel-framed buildings, sheds, mezzanines and to support openings in existing walls.
Key points
- Rolled steel sections in standard sizes
- Light and quick to erect
- Needs fire and rust protection
- Joined by welding or bolting
Why it matters
In RCC homes they are mostly used for renovations, extra floors in steel, staircases or terrace sheds.
How Elamentt handles it
We use steel sections where they suit the design, with a protective coating suited to Chennai's humid air.
