When working with structural steel sections like ISMC Channels, manual volume-based calculations are tedious. The industry relies on standardized weight charts—but understanding the underlying data is key to structural safety.
Indian Standard Medium Channels (ISMC) are essential structural elements in frames, supports, and heavy machinery housings. Manufactured hot-rolled under IS 808 standards, their weight is standardized to ensure predictability in engineering load calculations.
Standard ISMC weight per Meter (IS 808)
Below is the industry reference for common ISMC sizes used in Indian engineering and construction:
| Designation | Dimensions (mm) | Weight per Meter (kg/m) |
|---|---|---|
| ISMC 75 | 75 x 40 x 4.8 | 7.14 |
| ISMC 100 | 100 x 50 x 5.0 | 9.56 |
| ISMC 125 | 125 x 65 x 5.3 | 13.1 |
| ISMC 150 | 150 x 75 x 5.7 | 16.8 |
| ISMC 200 | 200 x 75 x 6.2 | 22.3 |
| ISMC 300 | 300 x 90 x 7.8 | 36.3 |

Manual Calculation Methodology
If you are dealing with a non-standard or custom-fabricated C-channel, you must calculate its sectional area manually:
Concept: Sum the areas of the Web and the two Flanges.
Sectional Area (A) ≈ (H × t) + (2 × B × t_f)
(Where H=Height, B=Flange Width, t=Web Thickness, t_f=Flange Thickness)
The Importance of Material Grade (IS 2062)
While the dimensions define the volume, the material grade (like IS 2062 E250) ensures the density (7850 kg/m³) and mechanical strength. For structural integrity, always verify that your ISMC channels come with Material Test Certificates (MTC) confirming compliance with IS 808.
