The rolled steel beams are designated by the series to which beam sections belong (abbreviated reference symbols), followed by depth in mm of the section and weight in kN per metre length of the beam, e.g., MB 225 @ 0.312 kN/m.
As per IS 808:1989, Hot rolled I sections are classified in to 5 series:
i) Indian Standard Joist/junior Beams (ISJB)
ii) Indian Standard Light Beams (ISLB)
iii) Indian Standard Medium Weight Beams (ISMB)
iv) Indian Standard Wide Flange Beams (ISWB)
v) Indian Standard Heavy Beam (ISHB)

Classification of Rolled Steel Beams in India
The classification of rolled steel beams in India is done based on their dimensions and properties. As per Indian Standards, rolled steel beams are classified into five series:
1. ISMB Series: This series of beams are medium weight beams that have a wide range of applications in construction. They are commonly used in building structures, bridges, and other civil engineering projects.
2. ISJB Series: This series of beams are light weight beams that are mainly used in small structures such as residential buildings, small bridges, and other similar projects.
3. ISLB Series: This series of beams are light weight beams that are commonly used in industrial structures such as factories, warehouses, and other similar projects.
4. ISMB Series: This series of beams are heavy weight beams that are mainly used in large structures such as high-rise buildings, bridges, and other similar projects.
5. ISWB Series: This series of beams are wide flange beams that are commonly used in construction projects that require high strength and stability.
Conclusion
In conclusion, the classification of rolled steel beams in India is done based on their dimensions and properties. As per Indian Standards, rolled steel beams are classified into five series which include ISMB, ISJB, ISLB, ISHB, and ISWB. Each series of beams has its own specific applications and is used in different types of construction projects.
