Miscellaneous Channels (MC) - MC310x74

Miscellaneous Channels sit alongside the Standard Channel series, filling in section sizes and proportions the C-series doesn't cover. Like standard channels, they offer a stiff, one-sided flange profile useful for framing, purlins, edge trim, and paired back-to-back box sections — MC shapes simply extend the range of depths and weights available to designers. Every MC shape in the CISC 12 range is available here as a free CAD block, with full dimension and property data included.
