IS 2062 vs IS 808
IS 2062 specifies the chemical composition and mechanical properties of
structural steel (material strength and quality),
while IS 808 defines the dimensions, weight per meter, and geometry
of rolled sections such as channels, beams, and angles.
Example: An ISMC 100 × 50 channel made from E250 Grade (IS 2062)
follows IS 808 for dimensions and IS 2062 for material strength.
MS Channels are produced by hot rolling steel billets into C-shaped cross-sections.
They offer excellent strength, rigidity, and weldability, making them ideal for heavy structural works, machinery frames,
vehicle chassis, and support systems.
MS Channel Weight Chart
The weight of MS channels depends on their web height, flange width, and thickness.
Theoretical weights are calculated using the density of steel (7.85 g/cm³) and
standard ISMC dimensions as per IS 808:1989.
*Theoretical values may vary slightly depending on manufacturing tolerances as permitted by BIS.
How to Calculate MS Channel Weight
The weight of an MS channel depends on its flange width, web height, thickness, and length.
You can calculate it using the standard formula:
Weight (kg) = (2 × Flange × Flange Thickness + ((Web - 2 × Flange Thickness) × Web Thickness)) × 0.00785 × Length
Where:
Flange and Web are in millimeters,
Flange Thickness and Web Thickness are in millimeters,
and Length is in meters.
If you want to calculate the exact weight including the fillet at the root, use:
Weight (kg) = [(2 × Flange × Flange Thickness) + ((Web - 2 × Flange Thickness) × Web Thickness) + Fillet Area] × 0.00785 × Length
Where Fillet Area ≈ 2 × (Root Radius)2 × (π/4 − 0.5)
Example (without root radius):
For an ISMC 100 channel with 100 mm web, 50 mm flange, 5 mm web thickness,
7.7 mm flange thickness, and 6 meters length:
Weight = (2 × 50 × 7.7 + (100 - 2 × 7.7) × 5) × 0.00785 × 6 ≈ 14.78 kg
Example (with root radius):
If the root radius is 7.6 mm:
Fillet Area = 2 × 7.6² × (π/4 − 0.5) ≈ 2 × 57.76 × 0.2854 ≈ 33.0 mm²
Weight = [(2 × 50 × 7.7 + (100 - 2 × 7.7) × 5) + 33.0] × 0.00785 × 6 ≈ 14.79 kg
This helps determine the weight per channel and the total weight for bulk quantities accurately.
Why Use an MS Channel Weight Calculator
Using an MS channel calculator offers multiple benefits:
- Accurate Weight Estimation: Essential for billing, procurement, and design verification.
- Cost Planning: Simplifies rate-based cost estimation for fabrication and construction.
- Project Efficiency: Reduces manual errors and saves time in quantity estimation.
- Engineering Precision: Ensures consistency with IS 808 standard sizes and tolerances.
