Steel bar is a kind of steel used for reinforced concrete and prestressed reinforced concrete ‌. ‌ Steel bars mainly bear tensile stress in concrete, especially deformed steel bars, due to the role of its ribs, and concrete has greater bonding capacity, can better withstand the action of external forces. Steel reinforcement is widely used in a variety of building structures, especially large, heavy, light thin-walled and high-rise building structures.

In the concrete building structure, the steel bar plays a different role, such as stress reinforcement, distribution reinforcement, stirrup, scaffolding reinforcement, etc., each steel bar has its specific function and use.

According to the "Global and Chinese steel bar industry market Status Research Report" released by Heshi Consulting Research Center, the global steel bar market has reached 224.56 billion US dollars in 2023, in China, the steel bar market maintains a stable growth trend, and the cumulative output value in 2024 has reached 226.3881 million tons, an increase of 3.2%. It is expected to grow to $317.48 billion by 2030.

The government has issued a series of policies to regulate and support the development of the steel industry. For example, in order to promote the green transformation and sustainable development of the industry, the state has implemented strict environmental protection policies, requiring enterprises to increase investment in environmental protection and adopt more environmentally friendly production technologies and materials. In addition, the adjustment of tax policy also affects the cost structure and development strategy of enterprises to a certain extent. These policies not only promote the healthy development of the industry, but also enhance the social responsibility of enterprises.
