T-shaped steel is a type of steel that is cast into a T-shaped shape. Named after its cross-section being the same as the English letter 'T'. There are two types of T-beams: 1. T-beams are directly cut from H-beams and use the same standard as H-beams (GB/T11263-2017), making them an ideal material to replace double angle steel welding. It has the advantages of strong bending resistance, simple construction, cost savings, and lightweight structure. 2. Hot rolled T-shaped steel, mainly used in mechanical and small hardware steel.
