Parameter Category
Detailed specifications
Product Name
Hot-rolled reinforcing steel for construction (including plain round bars and ribbed bars)
Core Material
Low-carbon steel, low-alloy steel; mainstream grades: HPB300 (plain round bars), HRB400/HRB400E (deformed bars with ribs), HRB500/HRB500E (high-strength deformed bars with ribs)
Appearance and Form
Smooth round bars: feature a smooth surface and excellent bending performance; ribbed bars: have a crescent-rib or equal-height rib design on the surface, enhancing their bond with concrete.
Common Specifications
Diameter: 6mm–40mm; Length: Standard fixed lengths of 9m/12m, with customized processing services available, including cutting, bending hooks, threading, and more.
Mechanical Properties
Yield strength: HPB300 ≥ 300 MPa, HRB400 ≥ 400 MPa, HRB500 ≥ 500 MPa; tensile strength, elongation, and other indicators all meet the requirements of national standards.
Processing Technology
Hot-rolled forming, straightening, cutting, CNC bending, and threading; seismic-grade products (with "E" marking) meet high-ductility performance requirements.
Implementation Standards
GB/T 1499.1-2017 (Hot-Rolled Plain Round Steel Bars), GB/T 1499.2-2018 (Hot-Rolled Deformed Steel Bars)
Core Product Advantages
• Rigorous Quality Control: Utilizing high-quality scrap steel and molten iron as raw materials, we produce and manufacture products through advanced hot-rolling processes. Each batch undergoes a triple-layered, stringent inspection process—covering mechanical property testing, metallographic analysis, and visual quality assessment—to ensure that all performance indicators meet precise standards, effectively eliminating structural safety risks at the source.
• Full-Specification Compatibility: Comprehensively covers a diameter range from 6mm to 40mm, offering a variety of product options such as smooth bars, ribbed bars, and high-strength bars. We also provide customized processing services tailored to project requirements—including cutting, bending with hooks, threading, and more—effectively reducing on-site construction procedures and boosting overall construction efficiency.
• Exceptional seismic performance: Rebars of seismic grades such as HRB400E and HRB500E boast outstanding ductility and impact toughness. They can effectively absorb energy under earthquake loads, preventing brittle fracture failure, making them ideal for high-seismic-resistance building projects and fully compliant with national design standards.
• Efficient Collaborative Load Transfer: Ribbed reinforcement bars feature a scientifically designed ribbed structure, enhancing their bond and anchorage strength with concrete by more than 30% compared to smooth round bars. This enables efficient stress transfer, fostering synergistic load distribution between the steel reinforcement and concrete, and significantly improving the overall structural load-carrying capacity.
• High cost-performance advantage: Leveraging scalable production and automated processing techniques to optimize costs, our products boast high material yield and minimal waste. Customized processing services help reduce on-site labor losses, enabling customers to effectively manage overall project expenses.
