T-shaped steel is a type of steel cast into a T-shaped shape. It is named because its cross section is the same as the English letter "T". T-shaped steel is divided into two kinds:
1. It is directly divided into H-shaped steel. T-shaped steel uses the same standard as H-shaped steel (GB/T11263-2017), which is the ideal material to replace double Angle steel welding. It has the advantages of strong bending resistance, simple construction, cost saving and light structural weight.
2. Hot-rolled T-shaped steel is mainly used in mechanical and filling hardware steel.
Specification
Common sizes of T steel include but are not limited to 25253, 30303, 30304, 40404, 40405, 45455, 50505, 50506, 60606, 60607, 60366, etc.
Application
1. Construction field: T steel is mainly used in construction to manufacture reinforced concrete components and steel structural components, such as beams, columns and other load-bearing structures. It can provide sufficient support and stability to improve the strength and stiffness of the structure.
2. Mechanical field: In mechanical manufacturing, T steel is used to manufacture various mechanical parts, such as shafts, gears, bearing seats, etc. Due to its high strength and stiffness, T-steel can withstand large loads and shocks, and is suitable for the manufacture of various mechanical equipment.
3. Shipbuilding field: T steel is mainly used in shipbuilding for the manufacture of beams, longitudinal beams and other load-bearing structures in hull structures. It can withstand large bending and shear forces, and has good bending strength and shear strength.
4. Petrochemical field: In petrochemical equipment, T steel is used to manufacture various pressure vessels, pipelines and other equipment. It can withstand high temperature, high pressure, corrosion and other harsh environment, with good corrosion resistance and fatigue resistance.
5. Bridge engineering: T steel is used as the main beam or beam in bridge construction, with high strength and stiffness, and can withstand large loads and deformation.
6. Vehicle manufacturing: In automobile manufacturing, T-steel can be used as the body skeleton or strengthening beam to improve the stiffness and strength of the body.
