Square T Beam
Square T-beam, also called T-shaped beam or Tee beam, is a type of structural beam with a T-shaped cross-sectional profile. Unlike a standard I-beam that has a central vertical web and horizontal flanges at the top and bottom, a T-beam has a vertical stem and a horizontal flange extending from the stem at the top. This configuration creates a cross-sectional shape that resembles the letter "T." A Square T-beam is characterized by having equal-length stem and flange portions, resulting in a symmetrical T-shape. The stem and flange can have varying dimensions and thicknesses, depending on the specific load bearing requirements and design considerations of the structure.
