Hemaokang Steel (Shandong) Co., Ltd. is proud to present our Carbon Steel Reinforced Rebar in diameters ranging from 8mm to 40mm, each accompanied by a comprehensive Mill Test Report for full traceability and quality assurance. As a newly established company in 2025 with an annual export value of US$50 million – US$100 million, we combine modern manufacturing capabilities with rigorous quality control to deliver rebar that meets international standards. Our products are designed for critical concrete reinforcement applications, offering consistent strength, ductility, and weldability. Whether you require standard lengths or custom dimensions, our flexible production lines ensure prompt delivery through the port of Qingdao to markets worldwide.

Product Features and Technical Specifications:

Material Integrity: Made from high-quality carbon steel, our rebar undergoes strict chemical composition analysis to ensure optimal carbon, manganese, and silicon content for enhanced mechanical properties.
Precision Manufacturing: Hot-rolled process controlled by advanced automation results in uniform deformation patterns (ribs) that maximize bond strength with concrete.
Dimensional Accuracy: Diameter tolerances comply with ASTM A615 / GB/T 1499.2 specifications, with deviation within ±0.5mm for diameters up to 20mm and ±1.0mm for larger sizes.
Mechanical Performance: Yield strength of 400 MPa or higher (HRB400/HRB500 grade available), tensile strength exceeding 540 MPa, and elongation of at least 16% for reliable ductility.
Full Traceability: Each batch is supplied with a Mill Test Report detailing chemical composition, heat number, physical test results, and compliance certificates. This document is essential for quality audits and regulatory acceptance.
Customizable Lengths: Standard lengths of 6m, 9m, 12m are available, with custom lengths up to 18m upon request. We can also cut and bend according to client drawings.
Surface Treatment: Natural black finish (mill scale) or optional epoxy coating for enhanced corrosion resistance (available upon request).
Packaging: Securely bundled with steel straps, with waterproof wrapping for sea freight protection. Bundles are labeled with product grade, size, heat number, and net weight for easy identification.

Typical Mechanical Properties (HRB400 Grade)
Parameter	Value	Test Method
Yield Strength (MPa)	400 – 540	ASTM A370
Tensile Strength (MPa)	540 – 700	ASTM A370
Elongation (%)	≥ 16 (in 200mm gauge)	ASTM A370
Bend Test	No cracks (180° bend)	ASTM A615
Carbon Equivalent (CEV)	≤ 0.52%	Chemical Analysis

Advantages for Your Projects:

Cost-Effective: Direct factory pricing eliminates middlemen, offering competitive rates without compromising quality.
Global Logistics: With Qingdao port as our main shipping hub, we ensure efficient container loading and timely delivery to North America, Europe, Africa, Southeast Asia, Oceania, and beyond.
Quality Assurance: Our ISO9001-certified quality management system governs every step from raw material inspection to final packaging. The Mill Test Report provides independent verification of each shipment.
Technical Support: Our experienced team (51–100 employees) includes metallurgists and engineers ready to assist with grade selection, welding procedures, and project specifications.
Flexible Order Quantities: From small custom runs to large bulk orders (thousands of tons), we accommodate various contract sizes with consistent quality.

Trust & Credibility: As a young but rapidly growing enterprise, Hemaokang Steel has already achieved an annual export turnover exceeding US$50 million, serving diverse markets across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and Asia. Our 51–100 dedicated employees operate from Liaocheng, Shandong, leveraging China’s steel production infrastructure. Each rebar bundle leaves our facility with a Mill Test Report that includes heat number, chemical analysis, and mechanical test data — offering full chain of custody for your inspection. Combined with our ISO9001 certification, these documents provide the transparency and reliability that construction professionals demand. Contact us today to discuss your project requirements or request a sample. We are committed to delivering carbon steel reinforced rebar that meets your exact specifications, on time and at competitive prices.

Frequently Asked Questions (FAQ)

Q: What grades of rebar do you supply?
A: We primarily supply HRB400 and HRB500 grades (equivalent to Gr.60 and Gr.75). Other grades such as B500B, B500C, or customized chemical compositions are available upon request.
Q: Do you provide a Mill Test Report for each batch?
A: Yes, every consignment is accompanied by a Mill Test Report that includes heat number, chemical composition percentage, yield and tensile strength, elongation, and bend test results. The report is issued by our in-house lab and can be certified by a third party if required.
Q: What is the minimum order quantity (MOQ)?
A: The MOQ for standard sizes (12mm–32mm) is typically 25 metric tons per size. For non-standard diameters or custom lengths, the MOQ may be higher. We are open to discussing smaller trial orders for new clients.
Q: How do you ensure the rebar meets international standards?
A: Our production follows ASTM A615, GB/T 1499.2, and BS 4449 standards. We also perform random third-party testing (e.g., SGS, BV) as requested by clients. The ISO9001 system ensures consistent process control.
Q: Can you supply pre-cut or bent rebar?
A: Yes, we offer cutting and bending services according to your bending schedules. Please provide detailed drawings or a list of BBS (Bar Bending Schedule) for accurate pricing.
Q: What are the payment terms?
A: Common payment terms include T/T (30% deposit, 70% against copy of shipping documents) and L/C at sight. Negotiable for long-term partnerships.
Q: How long does delivery usually take?
A: For standard sizes and lengths, production takes 15–20 days after receiving deposit. Shipping time depends on the destination: e.g., 25–30 days to Southeast Asia, 35–45 days to Europe, 20–25 days to the Middle East.
Q: Do you offer any corrosion protection?
A: Standard rebar has a natural mill scale surface. For additional corrosion resistance, we can apply epoxy coating (fusion-bonded) or galvanizing as per your specifications. This is a value-added service with extra lead time and cost.
