As a professional steel manufacturer, Hemaokang Steel (Shandong) Co., Ltd. takes pride in supplying the Carbon Steel Deformed Bar HRB400 with a fixed length of 12 meters. This ribbed-surface reinforcing bar is specifically engineered to deliver superior bond performance in concrete structures, ensuring maximum stability and load-bearing capacity. Widely used in bridges, high-rise buildings, tunnels, and industrial facilities, our HRB400 deformed bar combines high strength with excellent weldability and ductility. Every batch is produced under strict quality control to meet international construction standards and provide reliable reinforcement for your projects.
The HRB400 grade is recognized for its minimum yield strength of 400 MPa, making it a trusted choice for heavy-duty concrete reinforcement. The ribbed pattern, also known as deformed surface, significantly improves the mechanical interlock between steel and concrete, reducing slippage and increasing structural stability. Compared to plain round bars, deformed bars like HRB400 offer better anchoring performance, which is essential in seismic zones and high-stress applications. Our 12-meter fixed length helps minimize splicing and waste, enabling faster installation and cost-efficient construction.
Key Features & Benefits
- High Yield Strength: HRB400 provides a minimum yield strength of 400 MPa, ensuring robust structural support for heavy loads.
- Ribbed Surface: The deformed pattern enhances bonding with concrete, significantly reducing the risk of slippage.
- Fixed 12m Length: Standardized length reduces on-site cutting and waste, speeding up installation.
- Excellent Ductility: Allows bending and shaping without cracking, catering to complex construction designs.
- Consistent Quality: Produced under ISO 9001 quality management systems, ensuring uniformity in chemical composition and mechanical properties.
- Corrosion-Resistant Formulation: Optional epoxy coating or galvanization is available upon request for harsh environments.
- Customizable Diameters: Available in diameters ranging from 8mm to 40mm, tailored to project-specific engineering requirements.

Excellent Weldability and Machinability: The chemical composition of HRB400 carbon steel is carefully balanced to support welding and mechanical connection methods commonly used on construction sites. Whether you need to splice bars, anchor them into concrete, or fabricate complex reinforcement cages, this deformed bar adapts perfectly. The ribbed profile also allows for efficient load transfer, improving the overall safety and lifespan of concrete structures.
Wide Range of Applications: Our HRB400 deformed bar is a versatile choice for various construction projects. It is widely employed in reinforced concrete foundations, columns, beams, slabs, and shear walls. Infrastructure projects such as highways, port terminals, airports, and railway systems also benefit from its reliable performance. With a fixed 12-meter length, contractors can easily plan material usage and reduce waste, for both large-scale developments and smaller residential builds.
Rigorous Quality Assurance: Hemaokang Steel maintains a strict quality control process from raw material selection to final packaging. Our testing facilities verify the chemical composition, mechanical strength, and dimensional accuracy of every batch. We are committed to providing products that consistently meet or exceed industry specifications. The ISO 9001 certification further demonstrates our dedication to quality management and continuous improvement.

Frequently Asked Questions
Q1: What is the difference between HRB400 and plain round bars?
A1: HRB400 has a ribbed/deformed surface that provides much better bonding with concrete. This improves structural strength and resistance to slippage, making it ideal for reinforced concrete applications.
Q2: Can you supply other lengths besides the standard 12 meters?
A2: Yes, we can produce or cut to any custom length based on your engineering drawings. Typically, we offer lengths from 6m to 12m for easier transportation and site handling.
Q3: What are the available diameters for HRB400 deformed bars?
A3: Our standard diameter range is 8mm to 40mm, including sizes like 10mm, 12mm, 16mm, 20mm, 25mm, and 32mm. Other non-standard sizes may be available upon request.
Q4: Do you provide any surface treatment, such as epoxy coating or galvanizing?
A4: Yes, these are optional enhancements for environments with high corrosion risk. Please specify your requirement, and we will provide the appropriate solution and pricing.
Q5: How do you ensure the quality of the steel bars?
A5: We follow a strict quality control system under ISO 9001. Each batch is tested for chemical composition, yield strength, tensile strength, elongation, and dimensional accuracy before shipment.
Q6: What packaging options are available for export?
A6: We typically use steel straps and waterproof wrapping for sea freight. Custom packaging such as wooden crates or pallets is also available according to your instructions.
Q7: What is the minimum order quantity?
A7: The MOQ depends on the diameter and destination. For standard sizes, a 25-ton container load is usually acceptable. We can discuss based on your specific needs.
Q8: Can you assist with overseas shipping and documentation?
A8: Absolutely. We handle all export documentation, including commercial invoices, packing lists, and certificates of quality. Our logistics team coordinates shipments from Qingdao Port to your designated destination.
