It inherits geometry from the parent section and must be identified by its exact tee designation and listed properties. ## Common context Common project roles include specialty chords, reinforcement, lintels, connection components, and industrial framing that benefits from a particular tee proportion. ## Detailing watch Confirm parent-series geometry, stem and flange orientation, availability, connection eccentricity, and fabrication requirements instead of treating it as an interchangeable WT. Use the directory as a reference ## How to read the MT records MT identifies a tee from the M series. Read its exact tee dimensions rather than assuming a WT with a similar weight has the same flange or stem. Keep the tee centroid, flange orientation and distinct x- and y-axis properties with the exported geometry. This dataset contains 14 MT records, with nominal weights from 1.85 to 9.45 lb/ft and listed depth values from 1.9 to 6.27 in. These ranges describe the published records, not current supplier inventory or a selection recommendation. Start with the exact designation, open its full record, then compare only the dimensions and properties relevant to your task. For example, [MT5X3.75](https://www.quantumsteeldesign.com/steel-tools/shapes/mt5x3-75/) lists 3.75 lb/ft, 1.11 in² area, Ix = 2.91 in⁴ and Iy = 0.281 in⁴. The x and y labels retain the database axes; their values do not establish allowable loads. The [AISC v16.0 workbook Readme](https://www.aisc.org/aisc/publications/steel-construction-manual/aisc-shapes-database-v160/) defines the variables and shape figures. This directory uses the US customary record; the comparison tool converts displayed units. Check the required edition and product specification before transferring data. Worked quantity example ## Nominal weight for MT5X3.75 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 × 3.75 lb/ft | 75 lb | 34.019 kg | | 3 pieces | 3 × 75 lb | 225 lb | 102.058 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.
