Manufacturing process
I beams are hot-rolled from billets through universal or breakdown rolling mills, producing the characteristic narrow-flange, deep-web cross-section with controlled tolerances per IS 808, EN 10024 or JIS G3192.

I Beams
Hot-rolled I-section beams for floor, roof and bridge framing
I beams are hot-rolled structural sections with a characteristic narrow flange and deep web. They are highly efficient under pure bending loads, making them the workhorse section for floor and roof beams, secondary framing, crane gantries and bridge stringers.

Quick reference
I Beams: the essentials.
A concise, citation-ready summary used by search engines, AI assistants and procurement teams to answer common questions about i beams.
- I-beams are hot-rolled structural sections with a narrow flange and deep web, the classic 'I' profile.
- Sizes range from I 100 to I 600 (depth in mm), with flange widths 75 – 190 mm.
- Standards: IS 808, EN 10024, JIS G3192, GB/T 706, ASTM A36 / A572.
- Primary application is bending, floor and roof beams, crane gantries, bridge stringers.
- Distinct from IPE: IPE has parallel inner flange faces; traditional I-beams have tapered flanges.
Technical properties
Standard structural grades deliver 235 – 355 MPa yield strength. The tall, narrow geometry maximises section modulus relative to weight, making I beams highly efficient under pure bending.
Industry applications
Floor and roof beams, secondary framing in industrial sheds, crane gantry beams, bridge stringers, conveyor supports, and trailer / vehicle chassis framing.
Engineering guide
Understanding i beams.
What is an I-beam used for?
I-beams are the workhorse bending section in steel construction. Their tall, narrow geometry concentrates material at the extreme fibres where bending stresses peak, giving high section modulus per kg of steel. Typical applications include floor and roof beams, secondary framing in industrial sheds, crane gantry beams, bridge stringers, conveyor supports, and vehicle chassis.
I-beam vs H-beam: which is stronger?
Strength depends on the loading. I-beams are more efficient under pure bending, for a given weight, they carry more bending moment because the deep web maximises section modulus. H-beams are stronger under axial compression and biaxial loading because the wide flanges resist buckling in both directions. The rule of thumb: I-beams for beams, H-beams for columns.
