The difference between Q355B and Q235B high-strength steel for light poles

There are many types of steel used to make street light poles. Different steels have their own advantages and disadvantages. When using them, you should choose the appropriate steel according to the actual situation. 

The following is the difference between Q235b steel and Q355B steel used in street lamp poles 

1. Different yield strength 

The implementation standards of high pole lamps made of Q235b steel and Q355 steel are different. In steel, its yield strength is represented by Chinese pinyin numbers, and Q represents the quality grade. Therefore, the yield strength of lamp poles made of Q355B steel is higher than that of high pole lamps made of Q235B steel. 

2. Different mechanical properties 

In the study of the mechanical properties of steel, we can also clearly understand that the mechanical properties of Q355B are far greater than those of Q235B. The mechanical properties of the two are also quite different. If you want to improve the mechanical properties of the smart integrated pole, you can choose Q355B material. 

3. Different carbon structures 

The carbon structures of lamp poles made of Q235B steel and Q355B steel are also different, and the performance of different carbon structures is also different.
