MC7x19.1 – MC Shapes - American channels

MC7x19.1 is a channel 7 in (178 mm) deep with a 3.45 in (88 mm) flange, weighing 19.1 lb/ft (28.4 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.
