From designation to geometry
Reading the MC12X10.6 record
The 12 in depth series in MC12X10.6 is a designation. The tabulated depth d is 12 in and flange width bf is 1.5 in. The separately listed detailing depth ddet is 12 in.
The web thickness tw is 0.19 in and flange thickness tf is 0.309 in. This open channel also has centroid x = 0.269 in and shear-center offset eo = 0.284 in; preserve the toe direction and source axis convention when using those values.
Ix = 55.3 in⁴ and Iy = 0.378 in⁴ refer to the database x- and y-axes. Here Ix is numerically larger. Axis letters are labels, not a guarantee that x is always the larger axis. These are geometric properties, not allowable loads or complete member capacities.
Match the axis and dimension conventions to the figures in the AISC v16.0 workbook Readme. The profile above simplifies manufacturing geometry; its outline is not used to recalculate the published properties.
Worked quantity example
Nominal weight for MC12X10.6
Assume 3 pieces, each 20 ft (6.096 m) long. This is a hypothetical quantity example, not a stock-length or lifting recommendation.
| Quantity | Calculation | Nominal pounds | Kilogram equivalent |
|---|---|---|---|
| One 20 ft piece | 20 ft × 10.6 lb/ft | 212 lb | 96.162 kg |
| 3 pieces | 3 × 212 lb | 636 lb | 288.485 kg |
Conversion: 1 lb = 0.45359237 kg; displayed results are rounded. This multiplication excludes connection plates, bolts, weld metal, coatings, cutting allowances and actual material variation. Use the material takeoff for your own lengths and quantities.
Shape family context
What is a miscellaneous channel?
An MC-shape is a hot-rolled miscellaneous channel whose proportions differ from the standard C series. It remains an open, singly symmetric section and should be identified by its exact designation and properties.

Do not substitute a C-shape from nominal depth alone. Verify exact flange, web, gage, slope, availability, and connection geometry from the controlling record.

MC12X10.6 alongside nearby MC records
These records share the same nominal series, outside envelope or leg arrangement, depending on the family. Peers are ordered by absolute weight difference, then listed depth and designation. The table does not rank structural performance or approve a substitution.
| Record | Weight (lb/ft) | Depth (in) | Area (in²) | Ix (in⁴) | Iy (in⁴) |
|---|---|---|---|---|---|
| MC12X10.6 (this record) | 10.6 | 12 | 3.1 | 55.3 | 0.378 |
| MC12X14.3 | 14.3 | 12 | 4.18 | 76.1 | 1 |
| MC12X31 | 31 | 12 | 9.12 | 202 | 11.3 |
Relative to MC12X10.6, MC12X14.3 changes nominal weight by +3.7 lb/ft, listed depth by 0 in, and area by +1.08 in². At the same hypothetical 20 ft length, the nominal weight difference is +74 lb.

Data is derived from the AISC Shapes Database v16.0, consistent with the AISC Steel Construction Manual, 16th Edition, 1st Printing. AISC advises professional verification before use in a specific application. The downloadable DXF is a nominal reference profile and may simplify rolled fillets, flange tapers, angle radii, HSS corner radii, and other manufacturing geometry. Verify all dimensions and suitability before design, detailing, ordering, or fabrication.
