‌What is the role of Rebars?

Rebars are a type of steel used in building structures, mainly used to withstand tensile and compressive stresses to ensure the stability and safety of buildings. ‌ There are many types of steel bars, mainly including plain round steel bars and ribbed steel bars, of which ribbed steel bars are also called threaded steel bars. The diameter of steel bars usually ranges from 6mm to 50mm, and the commonly used diameters are 8, 12, 16, 20, 25, 32, 40mm, etc. ‌12

Rebars are widely used in construction, mainly in civil engineering construction such as houses, bridges, and roads. Threaded steel bars are the common name for ‌Hot rolled ribbed steel bars. According to their different yield points, they are divided into grades such as HRB400, HRB500, and HRB600. The production process of steel bars includes hot rolling, cold rolling, cold drawing, and other methods. Different processes will affect the performance and application scenarios of steel bars.

In building structures, steel bars mainly bear tensile stress, especially deformed steel bars, due to the effect of ribs, have a greater bonding ability with concrete and can better withstand the effects of external forces. The connection methods of steel bars include tying, welding and mechanical connection. The specific choice depends on the project needs and design requirements.
