T-beam

A T-beam (or tee beam), used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a capital 'T'-shaped cross section.

[2] The T-beam has a big disadvantage compared to an I-beam (with 'Ɪ' shape) because it has no bottom flange with which to deal with tensile forces, applicable for steel section.

A T-beam is a structural element able to withstand large loads by resistance in the beam or by internal reinforcements.

Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces.

The extra time and effort invested in creating a more complex structure may prove worthwhile if it is subsequently used in construction.

Steel T-beams manufacturing process includes: hot rolling, extrusion, plate welding and pressure fitting.

[7] Though the term could refer to any one of a number of means of reinforcement, generally, the definition is limited to concrete poured around rebar.

Concrete alone is brittle and thus overly subject to the shear stresses a T-beam faces where the web and flange meet.

The strong bond of the flange (horizontal section) and the two webs (vertical members) creates a structure that is capable of withstanding high loads while having a long span.
