WT12X58.5

Structural Tee (from W) · AISC Shapes Database v15.0 · United States

WT12X58.5 is a structural tee cut from a W-shape 307.3 mm deep with a 325.1 mm wide flange, weighing 87.1 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.

WT tees are W-shapes split at mid-depth — common truss chords and hangers, tabulated for the cut section.

Derived section properties

Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For WT12X58.5 the computed area is 0.77% from published and Ix 0.81%. Where a value is also published, the published one above is the one to quote.
