Difference between Q235B and Q355B steel plates used in LED street light pole

In today’s society, we can often see a lot of LED street lights on the side of the road. LED street lights can help us travel normally at night, and can also play a role in beautifying the city, but the steel used in the light poles is also If there is a difference, then, the following LED street light manufacturer TIANXIANG will briefly introduce the difference between the use of Q235B steel and Q355B steel for LED street light poles.

LED street light pole

1. Different yield strength

LED street light poles made of Q235B steel and Q355B steel have different implementation standards, because in steel, its yield strength is represented by Chinese pinyin numbers, and Q represents the quality grade. The yield strength of Q235B is 235Mpa, and the yield strength of Q355B is 355Mpa. Note here that Q is the symbol of yield strength, and the following value is the value of its yield strength. Therefore, the LED street light pole made of Q235B steel, The yield strength of light poles made of Q355B steel is higher.

2. Different mechanical properties

In the study of the mechanical capability of steel, we can also clearly understand that the mechanical capability of Q235B is far greater than that of Q355B. There is also a big difference between the mechanical capabilities of the two. If you want to improve the LED street light pole Mechanical ability, then you can choose Q235B material.

3. Different carbon structures

The carbon structure of the LED street light pole made of Q235B steel and Q355B steel is also different, and the performance of different carbon structures is also different. The material difference between Q355B and Q235B is mainly in the carbon content of steel. The carbon content of Q235B steel is between 0.14-0.22%, and the carbon content of Q355B steel is between 0.12-0.20%. In terms of tensile and impact tests, the impact test is not performed on Q235B steel, and the material is The steel of Q235B is subjected to impact test at room temperature, V-shaped notch.

4. Different colors

Q355B steel can be seen to be red with the naked eye, while Q235B can be seen to be blue with the naked eye.

5. Different prices

The price of Q355B is generally higher than that of Q235B.

The above is the difference between Q235B steel and Q355B steel used in LED street light pole. Now I believe that everyone has already understood the difference between the steel materials used in LED street light poles. In fact, there are many types of steel materials used to make LED street light poles. Different steel materials also have their own advantages and characteristics. They should be used according to the actual situation. Choose the right steel for your situation.
