Rebar is the common name for hot-rolled ribbed steel bars. It usually has the following characteristics:
I. Appearance and Specifications
Rebar has longitudinal ribs and transverse ribs on its surface, thereby enhancing its gripping force with concrete. Its specifications are usually expressed in diameter. Common ones are 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, etc.
II. Uses
- In the field of construction
- In various construction projects, rebar is an indispensable material. It is widely used in building houses, bridges, roads, dams and other infrastructure. For example, in high-rise buildings, rebar serves as the skeleton of concrete structures and bears the weight of buildings and various external forces.
- In bridge construction, rebar is used to reinforce parts such as bridge piers and bridge girders to ensure the stability and safety of bridges.
- In other fields
- Some manufacturing of mechanical equipment also uses rebar, such as structural parts of large construction machinery such as cranes and tower cranes.
III. Performance Characteristics
- High strength
- Rebar has high tensile strength and yield strength and can withstand large tensile and compressive forces. This enables it to effectively resist various external forces in building structures and ensure the stability of buildings.
- Good welding performance
- In construction, rebar often needs to be welded and connected. High-quality rebar has good welding performance and can ensure the strength and quality of welded joints.
- Corrosion resistance
- In order to improve the corrosion resistance of rebar, some anti-corrosion measures are usually adopted, such as galvanizing and painting. These measures can prolong the service life of rebar and reduce maintenance costs.
IV. Market Situation
- Price fluctuations
- The price of rebar is affected by many factors such as market supply and demand, raw material prices, and macroeconomic situation. Therefore, its price fluctuates frequently.
- Production and supply
- China is the world’s largest producer and consumer of rebar. There are many steel enterprises in China that produce rebar, and their production capacity and technical level are constantly improving. At the same time, with the promotion of the “Belt and Road” initiative, China’s rebar is also exported to many countries and regions.
