Advantages & Benefits for Your Business
Choosing Hemaokang Steel’s AISI 1020 deformed bar means investing in reliability and efficiency. The hot rolled process ensures a fine grain structure, enhancing toughness and fatigue resistance – critical for long-term structural performance. The deformed surface provides up to 40% better bond strength compared to plain round bars, reducing the required lap lengths and saving material costs. With diameters from 6mm to 32mm, you can cover a wide range of reinforcement needs from light residential slabs to heavy industrial foundations. Our ISO9001-certified production line guarantees every batch meets strict dimensional tolerances (within ±0.5mm on diameter) and mechanical properties, minimizing waste on site. Additionally, the low carbon content of AISI 1020 makes the bar highly weldable and bendable, allowing for easy customization without cracking. Whether you are a contractor, distributor, or precast manufacturer, our products help you achieve faster construction cycles and lower total project costs.
Frequently Asked Questions (FAQ)
-
Q1: What is the difference between AISI 1020 and AISI 1018 deformed bar?
AISI 1020 has slightly higher carbon content (0.18-0.23%) than 1018 (0.15-0.20%), offering higher strength while maintaining good weldability. It is commonly used for general construction reinforcement where moderate strength is required. -
Q2: Can you provide custom lengths?
Yes, we can cut bars to any length between 1m and 12m. For longer lengths (up to 18m), please contact our sales team for feasibility and shipping arrangements. -
Q3: Are these bars suitable for seismic zones?
AISI 1020 deformed bars offer good ductility (elongation ≥20%) and can be used in moderate seismic applications. For high seismic zones, we recommend consulting your structural engineer and consider higher-grade rebar such as A615 Grade 60. -
Q4: What is the minimum order quantity (MOQ)?
Our standard MOQ is 25 metric tons per size. Smaller trial orders (as low as 5 tons) are available upon request for new customers. -
Q5: Do you offer third-party inspection?
Absolutely. We welcome inspections by SGS, BV, or any other accredited agency. The cost can be shared or borne by the buyer as per the contract terms. -
Q6: How is the packaging for sea freight?
Bars are tightly bundled with steel straps, and each bundle is labeled with grade, size, heat number, and weight. For extra protection against moisture, we can add waterproof wrapping at an additional cost. -
Q7: What is the typical lead time for bulk orders?
For standard diameters (6-32mm), lead time is 15-20 days after receipt of down payment. For non-standard sizes, please allow 25-30 days. -
Q8: Are your products compliant with international standards?
While our bars are manufactured according to AISI 1020 chemical composition, they can also be produced to meet ASTM A615, BS 4449, or GB/T 1499.2 standards upon request. Please confirm your required standard before ordering.
