When it comes to structural integrity in modern construction, few components are as vital—and yet as overlooked—as the ISMC Channel. Whether you are building a massive industrial shed in the Bhogapuram airport zone or a residential complex in Madhurawada, choosing the right "C-channel" can make the difference between a structure that lasts for decades and one that faces costly maintenance issues.
At HeyBuildEX Anandapuram, we specialize in providing high-quality structural steel. In this comprehensive guide, we break down everything you need to know about Indian Standard Medium Weight Channels (ISMC), including size charts, weight calculations, and smart procurement tips.
ISMC stands for Indian Standard Medium Weight Channel. It is a hot-rolled structural steel section with a distinctive "C" or "U" shape. The design consists of a vertical web and two horizontal flanges.
The geometry of an ISMC channel is engineered for a superior strength-to-weight ratio. The flanges provide resistance to bending, while the web resists shear forces. This makes them ideal for:
In India, ISMC sizes are designated by their depth (the height of the web). For example, ISMC 100 refers to a channel with a 100mm web height.
To help you plan your project and estimate transportation costs, here is the standard weight chart for the most commonly used ISMC sizes available at our HeyBuildEX steel yard:
| Designation | Dimensions (mm) Depth × Flange × Web |
Sectional Weight kg/m |
Typical Applications |
|---|---|---|---|
| ISMC 75 | 75 × 40 × 4.8 | 7.14 | Light-duty frames, shelving, machine guards |
| ISMC 100 | 100 × 50 × 5.0 | 9.56 | Conveyor supports, stair stringers, equipment bases |
| ISMC 125 | 125 × 65 × 5.3 | 13.10 | Medium-duty mezzanine floors, roof purlins |
| ISMC 150 | 150 × 75 × 5.7 | 16.80 | Industrial sheds, heavy machinery mounts |
| ISMC 200 | 200 × 75 × 6.2 | 22.30 | Large structural frames, bridge decks, truck chassis |
| ISMC 250 | 250 × 82 × 9.0 | 34.20 | Heavy-duty infrastructure, factory frameworks |
Note: Standard lengths are usually 6 meters or 12 meters. At HeyBuildEX, we ensure our stock adheres to IS 808 standards for dimensional accuracy.
The versatility of ISMC makes it a "Swiss Army Knife" for engineers and fabricators. Here is where you will most commonly see these channels in action:
