Welcome to Hemaokang Steel (Shandong) Co., Ltd. — your reliable partner in high-quality steel construction materials. Our Hot Rolled Steel Rebar 10mm ~ 32mm with Yield Strength 420MPa is engineered to meet the demanding requirements of modern infrastructure projects. Manufactured under strict ISO9001 quality management system, this rebar offers excellent ductility and bond strength with concrete, ensuring structural integrity in bridges, buildings, roads, and industrial facilities. With an annual export value exceeding US$50 million and a growing global footprint, we are committed to delivering consistent quality and competitive pricing.
Our hot rolled deformed steel bar is available in a wide diameter range from 10mm to 32mm, all featuring a guaranteed yield strength of 420MPa. The ribbed surface ensures superior mechanical anchorage within concrete, reducing slippage and improving load transfer. Each batch is tested for dimensional accuracy, chemical composition, and mechanical properties to comply with international standards such as GB/T 1499.2 and ASTM A615 (available upon request). Whether you need standard lengths of 6m, 9m, or 12m, or custom lengths, we can accommodate your project specifications.
Key Features & Technical Specifications
- Consistent Yield Strength: 420MPa minimum, ensuring reliable performance under heavy loads.
- Wide Diameter Range: 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm — all available in stock.
- Excellent Ductility: Elongation ≥ 14% (typical), allowing for safe bending and shaping on site.
- Superior Bonding: Deformed pattern with longitudinal ribs and transverse lugs for maximum concrete grip.
- Rigorous Testing: Chemical analysis, tension, bend, and re-bend tests performed per batch.
- Corrosion Resistance: Hot rolled process produces a slight mill scale that is generally accepted for reinforced concrete; anti-corrosion packaging available for export.
- Customizable Options: Length, bundling, tagging, and third-party inspection available upon request.

Frequently Asked Questions
-
Q: What does “Yield Strength 420MPa” mean for construction?
A: It means the steel bar can withstand a tensile stress of at least 420 MPa before permanent deformation begins. This grade offers high strength, allowing designers to use smaller diameters while maintaining structural safety, which reduces weight and material costs in reinforced concrete projects. -
Q: What lengths are available? Can you cut to specific sizes?
A: Standard lengths are 6m, 9m, and 12m. We also offer custom cutting to your specified dimensions, typically with a tolerance of ±50mm. Please advise your requirements when ordering. -
Q: Do you provide samples for quality testing?
A: Yes, we can provide free samples (within 1 meter) for diameter 12mm, 16mm, or 20mm. You only need to pay for shipping. For other diameters or larger quantities, please contact our sales team. -
Q: Is your rebar suitable for welding?
A: Yes, our hot rolled steel rebar has a controlled carbon equivalent (Ceq ≤ 0.50%) to ensure good weldability. Always follow standard welding procedures and preheating recommendations for thick sections. -
Q: What packaging options do you offer for export?
A: We typically bundle rebar with steel strips (2–3 straps per bundle) and mark with tags. For sea freight, we can add waterproof wrapping or wooden crates as optional packaging at an extra cost. -
Q: How long does delivery usually take?
A: For standard sizes and quantities, production takes 7–15 days after order confirmation. Shipping time depends on destination. Our logistics team will coordinate the fastest route. -
Q: Do you accept third-party inspection?
A: Absolutely. We welcome inspections by SGS, Bureau Veritas, or any other accredited agency. The cost can be covered by the buyer or shared, as negotiated. -
Q: Can you supply rebar that meets ASTM A615 Grade 60 or BS 4449?
A: Yes, we can produce rebar to ASTM A615 Grade 60 (420 MPa yield) or BS 4449 Grade B500B upon request. Please specify your required standard when placing an order so we can adjust the chemistry and testing accordingly.
