A T-beam (or tee beam) steel is used in frame construction, is a load-bearing structure of metal, with a T-shaped cross section. The top of the T-shape cross section (vertical section) of the beam serves to resist shear stress and to provide greater separation for the coupled forces of bending.The standard commonly used structural steels are: Carbon steels, high strength low alloy steels, corrosion resistant high strength low alloy steels, tempered alloysteel and forged steel.Usually one end or both ends are anchored to the building structure.
