What Is ISMB?
ISMB stands for Indian Standard Medium Beam. It is a hot-rolled structural steel section with an I-shaped profile. The I-section consists of a vertical web and horizontal flanges that provide structural strength and efficient load-bearing performance.
ISMB beams are commonly used in:
- Industrial buildings
- Warehouses
- Factory structures
- Bridges
- Platforms
- Structural frames
- Columns
- Machinery supports
- Steel buildings
- Infrastructure projects
The designation generally indicates the nominal depth of the beam in millimeters. For example, ISMB 200 represents a beam with a nominal depth of approximately 200 mm.
For structural design and procurement, the exact section dimensions, unit weight, and applicable standard should always be verified against the project specification.
What Is ISMC?
ISMC stands for Indian Standard Medium Weight Channel. It is a hot-rolled structural steel channel with a C-shaped profile.
ISMC channels are commonly used for:
- Structural supports
- Industrial frames
- Purlins
- Bracing
- Platforms
- Machinery bases
- Trailer structures
- Fabrication
- Warehouse structures
- General engineering applications
The ISMC designation generally corresponds to the nominal channel depth. For example, ISMC 150 represents a channel with a nominal depth of approximately 150 mm.

ISMC Weight Chart 2026 Per Meter and Per 6-Meter
A simple way to understand an ISMC Weight Chart 2026 is to convert the unit weight from kilograms per meter into the approximate weight of a standard 6-meter length.
| ISMC Size | Weight kg/m | Approx. Weight for 6 m |
|---|---|---|
| ISMC 75 | 6.8 | 40.8 kg |
| ISMC 100 | 9.2 | 55.2 kg |
| ISMC 125 | 12.7 | 76.2 kg |
| ISMC 150 | 16.4 | 98.4 kg |
| ISMC 175 | 19.1 | 114.6 kg |
| ISMC 200 | 22.1 | 132.6 kg |
| ISMC 225 | 25.9 | 155.4 kg |
| ISMC 250 | 30.4 | 182.4 kg |
| ISMC 300 | 38.8 | 232.8 kg |
| ISMC 350 | 42.1 | 252.6 kg |

ISMB Weight Chart and ISMC Weight Chart 2026: How to Calculate Weight
The basic formula is
Total Weight = Weight per Meter × Length × Quantity
For example, if you require 20 pieces of ISMC 150, each having a length of 6 meters:
- ISMC 150 weight = 16.4 kg/m
- Length = 6 m
- Quantity = 20
Calculation:
16.4 × 6 × 20 = 1,968 kg
Therefore:
Total weight = 1,968 kg
or:
1,968 metric tons
This formula can be used for quick quantity estimation and purchase planning.
ISMC Weight Calculation Formula
The weight of a steel channel can also be calculated from its cross-sectional area and steel density.
Weight = Volume × Density
For steel, a commonly used density for calculation is approximately
7,850 kg/m³
When the cross-sectional area is known:
Weight per meter = Cross-sectional area × Steel density
However, because rolled structural sections include webs, flanges, fillets, and radii, using the standardized unit weight for the exact section is generally more practical than estimating the profile as simple rectangles.
ISMB Weight Calculation Example
Suppose you require:
ISMB 250
Unit weight:
31.5 kg/m
Required length:
12 metres
Quantity:
10 pieces
Calculation:
31.5 × 12 × 10 = 3,780 kg
Therefore:
Total weight = 3.78 MT
This method helps purchasing departments estimate the approximate tonnage required before requesting a quotation.

ISMB Weight Chart and ISMC Weight Chart 2026 for Project Estimation
An ISMB Weight Chart and ISMC Weight Chart 2026 can help project teams estimate the quantity of steel required before purchasing.
For example, if a project requires 100 meters of ISMC 150:
Unit weight = 16.4 kg/m
Total length = 100 m
Therefore:
16.4 × 100 = 1,640 kg
The approximate material requirement is:
1.64 MT
A project estimator can then multiply the estimated tonnage by the applicable current steel rate to obtain a preliminary material budget.
Current Steel Price Calculation Example
Suppose the quoted channel rate is:
₹59/kg
and the required ISMC material weighs:
1,640 kg
Estimated basic material value:
1,640 × ₹59 = ₹96,760
The final invoice may differ after adding applicable GST, freight, loading, unloading, cutting, and other commercial charges.
