Overview of B500B Rebar

Iran’s B500B rebar is one of the high-strength reinforcement steel bars, known for its capacity to withstand heavy loads and provide long-term durability. With specifications that meet international standards, this grade is widely used in large infrastructure projects and high-rise construction, making it a preferred choice for demanding environments. The ribbed texture of B500B rebar enhances its bonding with concrete, improving the structural integrity of the final construction.

Key Specifications of B500B Rebar

B500B rebar is characterized by its strong mechanical properties, which make it ideal for high-load applications in both industrial and commercial settings.

• Tensile Strength: B500B rebar has a tensile strength exceeding 500 MPa, making it suitable for high-stress applications.
• Yield Strength: With a minimum yield strength of 500 MPa, B500B rebar retains its shape under significant stress without deforming.
• Ductility: The high ductility of B500B rebar allows it to bend under pressure without fracturing, a critical property in earthquake-resistant structures.
• Corrosion Resistance: Treated for corrosion resistance, B500B rebar performs well in various environmental conditions, including humid and coastal regions.

The standards for B500B rebar align with global benchmarks set by organizations like ASTM and ISO, ensuring that it meets the requirements of modern construction projects.

Applications of B500B Rebar

Thanks to its specifications, B500B rebar is widely utilized in projects where strength and durability are paramount.

1. High-Rise Buildings: B500B rebar is commonly used in the core and support structures of high-rise buildings, ensuring stability and load-bearing capacity.
2. Infrastructure Projects: Bridges, tunnels, and highways often incorporate B500B rebar for enhanced resilience and structural strength.
3. Industrial Construction: In large industrial facilities, B500B rebar reinforces foundations and support structures, allowing them to bear the weight of heavy equipment and machinery.
4. Seismic-Resistant Structures: With its high ductility, B500B rebar is suitable for structures in earthquake-prone areas, absorbing shock without compromising stability.
