MC9x25.4 – MC Shapes - American channels

MC9x25.4 is a channel 9 in (229 mm) deep with a 3.5 in (89 mm) flange, weighing 25.4 lb/ft (37.8 kg/m).

MC shapes are additional standardized channel sections that sit outside the C-shape series — extra depth and weight combinations that fill gaps the standard C series doesn't cover. They're used the same way C shapes are — framing, bracing, purlins, and general structural channel applications — and are typically specified when a project's loading or geometry calls for a specific depth-to-weight combination that only the MC series provides.
