HRB**0/HRB**0 *2mm Round Steel Bar:



1. Material: HRB**0 or HRB**0 steel, which are hot-rolled ribbed bars used in reinforced concrete.

  

2. Diameter: *2mm, indicating the thickness of the round bar.



3. Grade:

   - HRB**0: Tensile strength typically around **0 MPa, yield strength of at least **0 MPa.

   - HRB**0: Higher tensile strength around **0 MPa, yield strength of at least **0 MPa.

   

4. Surface: Ribbed texture for better bonding with concrete, improving the overall structural integrity.



5. Application: Used in construction for reinforcing concrete structures such as columns, beams, and foundations.



6. Welding: Can be welded, but preheating may be required, especially for HRB**0, due to its higher strength and potential for brittleness.



7. Length: Often supplied in standard lengths (e.g., 6m, *2m) but can be cut to size.



8. Corrosion Resistance: Typically treated or coated to resist corrosion, although additional protection may be required depending on environmental conditions. 



This steel bar is essential for structural applications, ensuring durability and strength in various construction projects.
