I-Beam Weight Chart: ISMB Kg/m, 6m and 12m Weight Guide
I-Beam Weight Chart: ISMB Kg/m, 6m and 12m Weight Guide – In the world of construction and structural engineering, choosing the right steel section is one of the most critical decisions. Among the various steel components used in building frameworks, I-beams (Indian Standard Medium Beams – ISMB) are widely preferred for their strength, durability, and load-bearing capacity.
Whether you are constructing a residential building, industrial shed, bridge, or commercial complex, understanding the I-beam weight chart, kg per meter (kg/m), and total weight for 6m and 12m lengths is essential for accurate planning and cost estimation.
In this blog, we will provide a complete guide on ISMB beams, their weight calculations, standard sizes, and how trusted suppliers like Khandelwal Loha can help you get high-quality steel materials for your projects.
What is an I-Beam (ISMB)?
An I-beam, also known as an H-beam or ISMB (Indian Standard Medium Beam), is a structural steel component shaped like the letter “I”. It consists of:
- Flanges (top and bottom horizontal parts)
- Web (vertical section connecting the flanges)
This design allows the beam to withstand heavy loads while minimizing material usage, making it highly efficient for structural applications.
Why I-Beams Are Important in Construction
I-beams are widely used due to the following benefits:
- High load-bearing capacity
- Excellent bending resistance
- Cost-effective structural solution
- Suitable for long spans
- Durable and long-lasting
Because of these advantages, I-beams are commonly used in:
- Buildings and skyscrapers
- Bridges
- Industrial sheds
- Warehouses
- Infrastructure projects
Understanding ISMB Weight Chart (Kg/m)
The weight of an I-beam is usually measured in kilograms per meter (kg/m). This value helps engineers and contractors calculate the total weight required for a structure.
Below is a standard ISMB weight chart:
| ISMB Size | Weight (Kg/m) |
| ISMB 100 | 11.5 kg/m |
| ISMB 125 | 13.0 kg/m |
| ISMB 150 | 14.9 kg/m |
| ISMB 175 | 19.6 kg/m |
| ISMB 200 | 24.2 kg/m |
| ISMB 225 | 31.2 kg/m |
| ISMB 250 | 37.3 kg/m |
| ISMB 300 | 44.2 kg/m |
| ISMB 350 | 52.4 kg/m |
| ISMB 400 | 61.6 kg/m |
| ISMB 450 | 72.4 kg/m |
| ISMB 500 | 86.9 kg/m |
| ISMB 550 | 103.7 kg/m |
| ISMB 600 | 122.6 kg/m |
Weight Calculation for 6m and 12m I-Beams
To calculate the total weight of an I-beam, use the formula:
Total Weight = Weight per meter × Length of beam
Example Calculations
ISMB 200
- Weight per meter = 24.2 kg/m
- For 6m length = 24.2 × 6 = 145.2 kg
- For 12m length = 24.2 × 12 = 290.4 kg
ISMB 300
- Weight per meter = 44.2 kg/m
- For 6m = 265.2 kg
- For 12m = 530.4 kg
ISMB 400
- Weight per meter = 61.6 kg/m
- For 6m = 369.6 kg
- For 12m = 739.2 kg
Complete ISMB Weight Table (6m and 12m)
| ISMB Size | Kg/m | 6m Weight | 12m Weight |
| ISMB 100 | 11.5 | 69 kg | 138 kg |
| ISMB 150 | 14.9 | 89.4 kg | 178.8 kg |
| ISMB 200 | 24.2 | 145.2 kg | 290.4 kg |
| ISMB 250 | 37.3 | 223.8 kg | 447.6 kg |
| ISMB 300 | 44.2 | 265.2 kg | 530.4 kg |
| ISMB 350 | 52.4 | 314.4 kg | 628.8 kg |
| ISMB 400 | 61.6 | 369.6 kg | 739.2 kg |
| ISMB 450 | 72.4 | 434.4 kg | 868.8 kg |
| ISMB 500 | 86.9 | 521.4 kg | 1042.8 kg |
| ISMB 600 | 122.6 | 735.6 kg | 1471.2 kg |
Factors to Consider While Choosing I-Beams
When selecting the right ISMB beam for your project, consider the following:
1. Load Requirements
Ensure the beam can handle both dead load and live load.
2. Span Length
Longer spans require heavier and stronger beams.
3. Structural Design
Consult structural engineers for proper sizing.
4. Quality of Steel
Always choose high-grade steel to ensure safety and durability.
Applications of ISMB Beams
I-beams are used across multiple sectors, including:
- Residential construction – Support for roofs and floors
- Commercial buildings – Structural framework
- Industrial projects – Heavy machinery support
- Bridges and flyovers – Load distribution
- Warehouses – Roofing and structural stability
