WT7x21.5 – WT Shapes

WT7x21.5 is a tee 6.83 in (173 mm) deep with an 8 in (203 mm) flange, weighing 21.5 lb/ft (32.0 kg/m).

WT shapes are structural tees produced by splitting a W shape lengthwise down the centre of its web, yielding a T-shaped cross-section with the flange width and thickness of the parent W shape. They're used as chords in trusses and open-web steel joists, as flanges welded to plate to build up girders and other custom sections, and anywhere a single wide bearing flange on a stem is more structurally efficient than a full I-shaped section — typically where only one face of the member needs to carry a bearing or connection load.
