What is T-section?
T-section is a steel that is cast into a T-shape. It is named because its cross section is the same as the English letter "T". There are two types of T-beams:,
1. T-beams are directly divided from H-beams and this T-beams are used with the same standards as H-beams (GB / T11263-2017), and are ideal materials for replacing double angle steels. It has the advantages of strong bending resistance, simple construction, cost saving and light weight.
2. Hot-rolled T-shaped steels are mainly used in machinery and small hardware steel sections.
How to specify the T-sections?
There are three types of T-beam: TW, TM, and TN. TW means wide flange T-section, TM means middle flange T-section and TN means narrow flange T-section. It is expressed as: height H* width B *web thickness t1 *wing thickness t2.
