Building Elements -> Steelwork Canadian -> CA M Shapes

M shapes are wide-flange sections that fall outside the standard W-shape series — typically lighter, narrower-flange sections used where a compact beam or column is needed but a full W-shape would be heavier than necessary. They're found in light-duty framing, mezzanines, and smaller structural applications across Canada. Every M shape in the CISC 12 range is available here as a free CAD block, with full dimension and property data drawn directly from the CISC Structural Section Tables.
