Introduction
Steel is a material that is vital to the building industry and is also widely used for either structural and/or engineering applications in various countries. Specifically, China as one of the world’s most powerful and largest economy employs steel in a wide range of applications. This article is going to shed insight on the application of Chinese steel grades in engineering and structural usage, where varieties of Chinese steel grades are available.
Background
Today in China, there are numerous steel grade systems which are adopted throughout the country. Whilst, the most common standard is the China GB Standard recognized as the national standard of the People’s Republic of China (PRC). Additionally, the Steel Grades standard of GB/T700 which is related to quality carbon structural steel and GB/T1591 which is related to High Strength Low Alloy Structural steel are also employed.
Chinese Steel Grades for Engineering and Structural Usage
A variety of Chinese steel grades are available for engineering and structural purposes such as:
• Q460C for engineering purpose: This grade is used for manufacturing vessels, bridges, cranes, railway vehicles and more.
• Q235B for general purpose: This steel grade is used for constructions, engineering and mechanics works, agricultural implements, vehicles, etc.
• Q345B for heavy-duty structuring: This Chinese steel grade is employed for applications in building and restoring heavy-duty structures such as bridges, vessels, dams or railways.
• Q235A for sectional purposes: This grade is generally used in and between sections of a structure.
• Q345A and Q345D for bridge building: These steel grades are often employed in bridge constructions. They are suitable for hot dip galvanizing and provide superior strength and are heavily used in cross-girder structures.
Conclusion
In conclusion, Chinese steel grades have proven themselves to be essential for many engineering and structural applications. The various uses of Chinese steel grades have resulted in efficient and cheaper constructions for developing countries such as China. As the economy and demands of China increase, manufacturers rely on these reliable steel grades to produce tables and structures known for their superior strength.
