Hemaokang Steel (Shandong) Co., Ltd. proudly presents our premium Q235B SS400 hot rolled steel coil, pickled and oiled, tailored for demanding metal forming applications. With thickness options from 3mm to 20mm, this product combines the strength of Q235B and SS400 standards with a clean, rust-inhibited surface, ensuring consistent performance in stamping, bending, and deep drawing processes. As a newly established exporter backed by an annual export value of US$50 million to US$100 million, we deliver reliable quality and global logistics expertise.
Our pickled and oiled hot rolled coil removes mill scale and applies a thin oil film, providing a smooth surface that reduces tool wear and improves forming accuracy. Ideal for automotive parts, machinery frames, and general fabrication, this coil offers excellent weldability and ductility. Every coil is produced under strict quality control, with ISO9001-certified management systems ensuring batch-to-batch consistency.
Product Features & Benefits
- Superior Surface Quality: Pickling removes scale and rust, while oiling prevents corrosion during storage and transit, eliminating the need for additional surface preparation.
- Optimal Thickness Range: 3mm to 20mm thickness covers most metal forming requirements, from thin sheet components to heavy structural parts.
- Excellent Formability: Low carbon content and controlled rolling process provide high elongation and bendability, suitable for complex shapes without cracking.
- Consistent Mechanical Properties: Meets Q235B (GB/T 700) and SS400 (JIS G3101) standards with guaranteed yield strength and tensile strength.
- Wide Width Options: Available in customizable widths typically from 900mm to 1500mm, allowing efficient material utilization for your production.
- Cost-Effective Solution: Pickled and oiled coils reduce downstream processing costs, as they are ready for immediate forming or painting.
- Reliable Supply Chain: We maintain ample stock and fast delivery to global markets, including North America, Europe, Asia, and Africa.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between Q235B and SS400?
A: Q235B is a Chinese standard (GB/T 700) carbon structural steel, while SS400 is a Japanese standard (JIS G3101). Both have similar yield and tensile strengths, and our coils are produced to meet either specification. Often they are interchangeable for many forming applications, but we recommend verifying your project's specific requirements. -
Q: Can you provide coils with a thickness outside 3-20mm?
A: Our standard production range is 3mm to 20mm. For thicknesses outside this range, please contact us with your requirements – we may be able to arrange custom rolling on request. -
Q: How long does the pickled and oiled surface protection last?
A: The oil film provides temporary rust protection for several months under normal dry storage conditions. For extended storage, we recommend keeping the coils in a covered, dry area. We can also apply additional rust preventive oil if needed. -
Q: What is the minimum order quantity (MOQ)?
A: Our typical MOQ is 1 coil (about 3-15 tons). For smaller quantities, please inquire – we may have stock available for split orders. -
Q: Do you supply test certificates and mill certificates?
A: Yes, we provide a Mill Test Certificate (MTC) for each batch, showing chemical composition, mechanical properties, and compliance with Q235B or SS400 standards. Additional third-party inspection is available upon request. -
Q: Can you ship to my country? What are the typical lead times?
A: We ship to all major global markets. Lead time depends on quantity and destination – typically 15-30 days after order confirmation for standard sizes. We can arrange sea, air, or rail freight as per your preference. -
Q: Are these coils suitable for deep drawing?
A: Yes, the pickled and oiled surface plus the ductility of Q235B/SS400 make them suitable for moderate deep drawing applications. For very severe forming, we recommend consulting our technical team to verify the specific grade. -
Q: Does your company provide samples?
A: Yes, we can provide small samples (e.g., 300mm x 300mm cut pieces) for evaluation. The sample is free of charge, but the customer pays for shipping. Contact us to arrange.
