ISMC (Indian Standard Medium Weight Channel) is a standardized structural steel channel section defined under IS 808 and commonly used in Indian construction and fabrication. It features a C-shaped profile with a vertical web and parallel/tapered flanges, providing good strength for structural framing, bracing, and support applications. ISMC sections are identified by their nominal depth in millimetres, such as ISMC 100 or ISMC 200, with fixed weights per meter specified by the standard.
