WT18x91 – WT Shapes

WT18x91 is a tee 18.2 in (462 mm) deep with a 12.1 in (307 mm) flange, weighing 91 lb/ft (135.4 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.
