As a leading manufacturer of hot rolled pickled carbon steel coils, Wuxi Yansheng Technology Co., Ltd. brings over 7 years of dedicated experience to the global steel market. Our Q235 and SPHC grades are specifically engineered for pipe making, offering superior formability, weldability, and consistent surface quality. With an annual export value exceeding US$50 million and a team of 101-200 skilled professionals, we ensure every coil meets the rigorous demands of international clients across North America, Europe, Southeast Asia, and beyond.
Our hot rolled pickled coils undergo a precise pickling process to remove scale and impurities, resulting in a clean, uniform surface that enhances downstream processing. The Q235 and SPHC carbon steel grades are widely recognized for their excellent mechanical properties, making them ideal for manufacturing welded pipes, precision tubes, and structural components. Whether you require standard dimensions or customized specifications, our factory with 1,000-3,000 square meters of production space is equipped to deliver consistent quality with fast turnaround times.
Key Features and Benefits:
Superior Surface Quality – The pickling process eliminates scale, ensuring a smooth, clean surface that reduces wear on tooling and improves paint or coating adhesion.
Excellent Formability – Q235 and SPHC offer exceptional ductility and bending properties, allowing for easy pipe forming without cracking or defects.
Consistent Mechanical Properties – Tight control of chemical composition and rolling parameters guarantees uniform tensile strength, yield strength, and elongation across every coil.
Enhanced Weldability – Low carbon content and optimized microstructure enable reliable welding for seamless pipe production.
Customizable Dimensions – Thickness from 1.5mm to 20mm, width from 600mm to 2000mm, and coil weight up to 20 tons, all tailored to your specific pipe making requirements.
Cost-Effective Solution – Hot rolled pickled coils eliminate the need for additional surface preparation, reducing overall production costs and cycle time.

Frequently Asked Questions:
What is the minimum order quantity for this coil?
Our MOQ is typically 25 tons for standard sizes, but we can accommodate smaller trial orders upon request. Please contact our sales team for specific details.Can you provide custom thickness and width?
Yes, we offer customization within our production range. Thickness from 1.5mm to 20mm and width from 600mm to 2000mm are available. Custom dimensions may require a minimum order.What is the lead time for production?
For standard specifications, lead time is 15-20 days after order confirmation. Custom orders may take 25-30 days depending on complexity.How is the coil packaged to prevent damage during shipping?
Each coil is securely wrapped with waterproof paper, steel strapping, and edge protection. We also offer additional packaging options such as wooden crates for extra protection.What payment terms do you accept?
We accept T/T (30% deposit, 70% before shipment) and L/C at sight. For long-term partnerships, other terms may be negotiable.Do you provide mill test certificates?
Yes, each shipment comes with a mill test certificate documenting chemical composition and mechanical properties. Third-party inspection is also available upon request.Can this coil be used for high-frequency welded pipe?
Absolutely. Q235 and SPHC are widely used for ERW (electric resistance welded) pipe production. The pickled surface improves weld quality and reduces electrode wear.What is the difference between Q235 and SPHC for pipe making?
SPHC has lower carbon content and higher elongation, making it more suitable for severe forming operations. Q235 offers higher strength and is often used for structural pipes. Both are excellent choices; we can recommend based on your specific application.
