Hot Rolled Ribbed Steel Bars

Hot Rolled Ribbed Steel Bars are a steel bar product with significant mechanical bite performance. The surface longitudinal and transverse ribs are processed in one step by a hot rolling forming process. It is widely used in reinforced concrete structures and is a key structural material for modern buildings and large-scale infrastructure projects.

Dimensional stability
Hot Rolled Ribbed Steel Bars are processed using high-precision continuous rolling equipment and advanced temperature control technology to ensure that the finished product size accuracy is controlled within ±0.3mm, which improves the assembly efficiency and reinforcement consistency during the construction process.

Excellent strength
Through the hot rolling controlled cooling process (TMCP), the internal crystal structure of Hot Rolled Ribbed Steel Bars is optimized to achieve a yield strength of more than 500MPa, meeting the requirements of high-strength structural design, and is particularly suitable for large load-bearing components.

Bond enhancement
The surface ribs of Hot Rolled Ribbed Steel Bars are rolled using a special mold, and the rib shape is uniform and reasonably distributed, which greatly enhances their anchoring ability with concrete, and the bonding performance can be improved by up to 1.4 times that of plain round steel bars.

Good weldability
The carbon content of Hot Rolled Ribbed Steel Bars is controlled at ≤0.25%, and the content of impurity elements is extremely low, ensuring its stability and safety in welding processes such as gas-shielded welding and arc welding, and is suitable for complex structure splicing.

Strong ductility
Using controlled rolling and grain refinement technology, the elongation of Hot Rolled Ribbed Steel Bars is increased to more than 16%, enabling it to have better energy absorption and plastic deformation capabilities in scenarios such as earthquakes and high dynamic loads.

Grade 60 (B500B)
Diameter: 10mm to 32mm
Applications: Commonly used in construction projects with high strength requirements, such as commercial buildings, bridges, and high-rise buildings. The steel bar has an excellent bond with concrete, ensuring the structural integrity of large projects.

Grade 40 (B400B)
Diameter: 8mm to 25mm
Applications: Suitable for projects such as small residential construction, light commercial construction, and foundation reinforcement.

Grade 80 (B500C)
Diameter: 12mm to 50mm
Applications: Designed to withstand heavy loads and high-stress environments, such as highways, bridges, and large industrial buildings.

Grade 500
Diameter: 10mm to 40mm
Applications: Commonly used in major infrastructure projects, such as dams, tunnels, and multi-story buildings.
