Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your trusted partner in high-quality steel products. As a newly established company in 2025 with an annual export value ranging from US$50 million to US$100 million, we are committed to delivering deformed steel bars that meet the highest standards of strength and durability. Our 12-meter length deformed steel bars come with comprehensive technical support and rigorous quality assurance, ensuring your construction projects achieve optimal performance and safety. Leveraging our ISO9001-certified production processes and a team of 51-100 skilled professionals, we guarantee consistent quality and timely delivery from our port of shipment in Qingdao.
Our deformed steel bars are designed for concrete reinforcement in various infrastructure projects, including bridges, highways, buildings, and industrial facilities. The ribbed surface provides superior bond with concrete, enhancing structural integrity. With a wide range of diameters and grades available, we offer flexibility to meet specific engineering requirements. Below, we detail the key features, technical specifications, and benefits of our product.
Key Features & Technical Specifications
- Material: High-quality carbon steel with controlled chemical composition for consistent mechanical properties.
- Surface Pattern: Deformed (ribbed) pattern for enhanced bonding with concrete, reducing slippage under load.
- Length: Standard 12 meters, with custom lengths available on request.
- Grades: HRB400, HRB500, and equivalent international grades (e.g., ASTM A615 Grade 60, BS4449 Grade B500B).
- Yield Strength: 400-500 MPa, ensuring high load-bearing capacity.
- Elongation: ≥16% (for HRB400) and ≥14% (for HRB500) to provide ductility under stress.
- Bendability: Excellent cold bending performance, meeting standard bend test requirements.
- Surface Treatment: Available in plain finish or with optional epoxy coating for corrosion resistance.
- Quality Assurance: 100% factory inspection with tensile, bend, and chemical analysis tests; ISO9001 certified.
- Packaging: Securely bundled with steel straps to prevent damage during transit; each bundle labeled with grade, size, and heat number.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity for your deformed steel bars?
A: For standard sizes (12m length, common diameters), our minimum order quantity is 20 metric tons. For custom sizes or special requirements, please contact us to discuss. -
Q: Do you provide third-party inspection certificates?
A: Yes, we can arrange third-party inspection by SGS, BV, or other accredited agencies at the buyer's request. The cost is typically included in the quotation upon request. -
Q: How long does delivery take from Qingdao port?
A: Typically, production takes 15-20 days after order confirmation, and shipping time depends on the destination. For example, to Southeast Asia it takes about 7-10 days by sea, to North America about 20-25 days. -
Q: Can you supply deformed bars with epoxy coating for corrosion protection?
A: Yes, we offer epoxy-coated deformed bars as an optional surface treatment. Please specify the coating thickness and standard (e.g., ASTM A775) when ordering. -
Q: What grades are available for your 12m deformed steel bars?
A: We offer HRB400, HRB500, and equivalent grades such as ASTM A615 Grade 60, BS4449 Grade B500B, and GB1499.2. Other grades can be customized per your requirements. -
Q: Do you provide technical documentation like mill test certificates?
A: Absolutely. Every shipment comes with a Mill Test Certificate (MTC) showing chemical composition, mechanical properties, and heat number. We also provide additional documents like certificate of origin, packing list, and bill of lading. -
Q: How do you ensure the quality of the deformed bars?
A: Our quality assurance system is ISO9001 certified. We conduct in-process and final inspections including tensile testing, bend testing, dimensional checks, and chemical analysis. Random samples from each batch are tested in our lab. -
Q: What is the payment term for international orders?
A: Common payment terms are T/T (30% deposit, 70% against copy of shipping documents) or L/C at sight. For regular customers, other terms may be negotiable.
