T-beam

Cross-sectioned structural support

A T-beam is a structural beam with a cross-section shaped like the letter T—a horizontal flange on top of a vertical web.

The design efficiently resists bending forces, making T-beams common in reinforced concrete construction for floors, bridges, and parking structures.

In concrete construction, the flange is often formed by the slab itself: The floor slab acts as the flange of the T-beam.
