At Hemaokang Steel (Shandong) Co., Ltd., we are committed to delivering high-quality carbon steel coils specifically engineered for automotive frame manufacturing. Our ASTM A569 carbon steel coil with a thickness range of 0.8-3.0 mm offers the perfect balance of strength, formability, and consistency required for critical automotive structural components. Backed by our ISO9001 certified production processes and a dedicated team of 51-100 employees, we ensure every coil meets the rigorous demands of the automotive industry.
This product is designed to provide superior weldability and dimensional accuracy, making it an ideal choice for chassis frames, cross members, and other load-bearing parts. With an annual export value exceeding US$50 million, we have established a reliable supply chain that serves markets across North America, South America, Europe, Asia, and beyond. Our coils are shipped from the port of Qingdao, ensuring efficient logistics to global customers.
Below, we detail the key features, technical specifications, and advantages that make our carbon steel coil a preferred solution for automotive frame manufacturing.
Key Features & Benefits
- Premium Material Quality: Manufactured from low-carbon steel per ASTM A569, ensuring excellent ductility and toughness for forming operations without cracking.
- Precise Thickness Control: Available in 0.8mm to 3.0mm with tight tolerances (typically ±0.05mm), critical for consistent part dimensions in automated assembly lines.
- Superior Surface Finish: Pickled and oiled surface treatment removes mill scale and provides corrosion protection during storage and transit; optional additional coatings available upon request.
- Excellent Weldability: Low carbon content (typically ≤0.15%) enables strong, clean welds with minimal spatter, reducing post-weld cleaning time.
- Formability & Bendability: High elongation (≥30%) allows complex bending, stamping, and deep drawing operations required for frame components.
- Customizable Dimensions: Coil width can be tailored from 600mm to 1500mm; slit widths and specific coil weights (3-10 tons) are available to match your production needs.
- Consistent Mechanical Properties: Tensile strength typically 310-410 MPa and yield strength 170-230 MPa, providing reliable performance under dynamic loads.
- Cost-Effective Solution: Optimized chemistry reduces material waste and scrap rates, improving overall manufacturing efficiency.

Why Choose Hemaokang Steel for Your Automotive Frame Manufacturing?
Our carbon steel coil is produced under strict quality control systems that comply with ISO9001 standards. We understand that automotive frame components demand high consistency and reliability, so we conduct rigorous testing on each coil, including chemical analysis, tensile testing, and dimensional checks. Our facility in Liaocheng, Shandong, utilizes advanced rolling mills to achieve uniform thickness and flatness.
We have served clients across more than 10 major markets globally, including North America, Europe, and Southeast Asia. Our annual export value of US$50-100 million reflects the trust that automotive manufacturers place in our products. We offer flexible packaging options (eye-to-sky, eye-to-wall, or horizontal) and can arrange just-in-time shipping to minimize inventory costs.
Additionally, we provide technical support for material selection, forming simulation, and welding parameters to help you optimize your production process. Our team of 51-100 experienced professionals is dedicated to ensuring your satisfaction from inquiry to delivery.
Frequently Asked Questions (FAQ)
1. What is the typical lead time for carbon steel coil orders?
Our standard lead time is 15-20 working days after confirmation of order and receipt of deposit. For urgent requirements, we can expedite production to 10-12 working days subject to availability.
2. Can you supply coils with specific widths or custom inner diameters?
Yes, we offer slitting services to achieve widths from 600mm to 1500mm, and inner diameters of 508mm or 610mm are standard. Custom dimensions are available upon request; please contact our sales team for details.
3. Is this material suitable for high-strength automotive frame applications?
ASTM A569 is a low-carbon steel grade suitable for non-critical structural parts where high strength is not required. For higher strength requirements, we recommend our HSLA grades (e.g., ASTM A572) which are also available. We can advise based on your specific application.
4. What surface treatments do you offer besides pickled and oiled?
We can supply coils with dry surface (no oil), light oil coating, or with a protective film for highly sensitive applications. Please specify your preference during ordering.
5. How do you ensure the coil does not have edge defects or shape issues?
We perform 100% visual inspection plus automated edge detection and shape measurement systems. Any coil with edge cracks, heavy burrs, or wavy edges is rejected before packaging. Our quality report is provided with each shipment.
6. Can you provide samples for testing before bulk order?
Yes, we offer sample coils (typically 100-200 kg) for evaluation. The sample cost is reasonable and can be deducted from your first order. Please contact us to arrange shipping.
7. What are the shipping terms and port of loading?
We ship from Qingdao Port, China. Common trade terms include FOB, CIF, CFR, and DDP. We can work with your preferred freight forwarder or arrange shipping ourselves.
8. Is your production process environmentally friendly?
We comply with all applicable environmental regulations in China. Our steel is sourced from mills that use energy-efficient technologies, and we recycle scrap material generated during slitting and processing.
We invite you to experience the reliability and quality of Hemaokang Steel. With our ISO9001 certification, global export experience, and dedicated team, we are your trusted partner for carbon steel coils in automotive frame manufacturing. Contact us today for a quote or technical consultation.
