T-beam(or tee beam) is one of the most commonly used steels today, and it is a kind of steel that is cast into a T-shape. It is named after its cross section is the same as the English letter “T”. The T-beam code corresponds to the H-beam, and TW, TM, and TN are used to represent the wide-flange T-beam, the middle-flange T-beam, and the narrow-flange T-beam, respectively. The representation method is also the same as that of the H-beam. Its expression method is: height H width B web thickness t1 wing thickness t2. There are many kinds of T-beam, which is an ideal material to replace double angle steel welding. It is widely used in transportation, construction, decoration and manufacturing. In terms of production, the production size can be appropriately adjusted according to different needs, and the production can be produced on demand.

According to the production method, T-beam can be divided into two types:

1. It is made of H-beam directly divided into T-beam. The standard is the same as that of H-beam (GB/T11263-2017). It is an ideal material to replace double angle steel for welding. It has the advantages of strong bending resistance, simple construction, cost saving and light weight of the structure. Widely used in machinery manufacturing, railway construction, curtain wall decoration, vehicle manufacturing and other industries.

2. Hot-rolled T-beam is mainly used in machinery and small hardware section steel. The representation method of hot-rolled T-beam: height H*width B*web thickness t1*flange thickness t2. For example: T-section steel Q235B or SS400 220*220*10*14 is represented as a T-section steel with a height of 220mm and a width of 220mm with a web thickness of 10mm and a wing thickness of 14mm. Its grade is Q235B or SS400.

According to different needs, T-beam can be divided into:

According to different needs and different processing methods, T-beams have different standards. It is roughly divided into T-section steel for railway, special-shaped welded T-section steel, special-shaped hot-rolled equi-thickness T-section steel, special-shaped bolted T-section steel and small T-section steel hardware.

Characteristics of T-beam

1. With strong integrity and high strength, it can be directly used as the roof joist of the pillar, and the flexural section modulus of the T steel belt is increased by 37 times.

2. The design is ingenious. The T-shaped steel belt is designed with double holes, which makes up for the unfavorable factors of support due to the failure of individual anchor cables or bolts.

3. High efficiency, bolts and cables are reinforced through strong T-shaped steel belts, which saves bolt trays, anchor cable trays, labor and materials, and is conducive to improving the excavation speed.

4. High strength, light weight, low cost, fine workmanship, convenient and quick installation, high support strength, safety and reliability.

5. The T-shaped steel strip has the advantages of better supporting effect, stable quality and low cost by using hot-rolled one-time forming.

6. High section utilization rate, material saving and low price.
