What is t-shaped steel

T-shaped steel is a steel that is cast into a T-shape.

It is named because its section is the same as the English letter “T”.

There are two types of T-shaped steel:

 

1. It is directly divided into H-shaped steel by H-shaped steel. The standard is the same as that of H-shaped steel (GB/T11263-2010), which is an ideal material to replace double-angle steel welding. It has the advantages of strong bending resistance, simple construction, cost saving and light weight.

2. T-shaped steel that is hot-rolled once is mainly used in machinery and small-sized steel.

Packing

 

1): Paint oil on the surface to protect steel bars from rusting.

2): Bundle packing by Iron Strips.

3): Bundle weight is from 2mt to 3mt.

4): Two or three tags will be attached on each bundle. In general, at one end of each bar

Packaging Details: standard seaworthy packing as customer’s requirement


Representation of hot rolled T-beam:

The T-shaped steel code corresponds to the H-shaped steel, and the TW, TM, and TN respectively represent the wide flange T-shaped steel, the middle flange T-shaped steel, and the narrow flange T-shaped steel.

The representation method is: height H width B web thickness t1 wing thickness t2,

Such as T-shaped steel Q235B or SS400 200*200*8*12

It is expressed as T-shaped steel with a height of 400mm and a width of 200mm and a web thickness of 8mm and a wing thickness of 12mm, and its grade is Q235B or SS400.
