Structural steel is generally used for bearing and other purposes. Engineering structural steel is a kind of steel often used in various projects. 

We all know that structural steel is mainly used to manufacture engineering structures and mechanical structures. 

Structural steel mainly includes two categories of engineering structural steel and mechanical manufacturing structural steel. 

Engineering structural steel is commonly used in places such as the manufacture of bridges, ship hulls, oil wells or mine derricks, rails, various high-pressure vessels and pipelines, building steel structures, etc. Engineering structural steel is required to be able to withstand various loads. 

Relatively high yield strength, engineering structural steel must have good plastic toughness, so as to ensure the reliability of the engineering structure in use.

In addition, engineering structural steel is generally used outdoors, so the working environment of engineering structural steel is exposed to the atmosphere, and the temperature in some places where engineering structural steel is used will be very low, so in these places it is required to Low temperature toughness is used, and engineering structural steel is also required to be resistant to atmospheric corrosion.
