Welcome to Wuxi Yansheng Technology Co., Ltd. – your trusted manufacturer of high-quality Hot Rolled Carbon Steel Coil in grades Q195, Q235, Q345, Q355, and ASTM A36. With over 7 years of experience and an annual export value exceeding US$50 million, we deliver reliable steel solutions for global industries. Our coils are produced under strict quality control and are available in both HRC (hot rolled) and CRC (cold rolled, annealed) options to meet diverse project requirements. Whether you need structural steel for construction or specialized coils for automotive parts, our products offer excellent formability, weldability, and strength.
Product Features & Technical Specifications
Superior Quality: Manufactured from prime carbon steel billets, ensuring consistent chemical composition and mechanical properties.
Versatile Grades: Available in Q195 (low carbon, good for drawing), Q235/Q345/Q355 (structural grades), and ASTM A36 (equivalent to Q235) – all with controlled tensile strength and yield point.
Annealed Option: Our CRC (cold rolled) coils undergo annealing to improve ductility and reduce internal stress, ideal for deep drawing and stamping applications.
Customizable Dimensions: Thickness from 1.2mm to 25mm, width from 600mm to 2000mm, and coil weight up to 10 tons – tailored to your production needs.
Surface Treatment: Pickled, oiled, or dry finish available to prevent rust during transit and storage.
Strict Tolerances: Conforms to GB/T 709, ASTM A635/A635M, and international standards.

Frequently Asked Questions (FAQ)
Q: What is the difference between Q195 and Q235 steel coils?
A: Q195 has lower carbon content and yield strength (≥195 MPa), making it suitable for drawing and forming. Q235 has higher strength (≥235 MPa) and is commonly used for structural applications. Both are available in our hot rolled coils.Q: Can you provide cold rolled (CRC) or annealed coils?
A: Yes, we offer both HRC and CRC options. CRC coils are annealed to improve ductility and surface finish, ideal for precision stamping and deep drawing.Q: What are the standard dimensions you produce?
A: Standard thickness ranges from 1.2mm to 25mm, width from 600mm to 2000mm, and coil weight up to 10 tons. Custom sizes are available upon request.Q: Do you have certifications for these coils?
A: Our factory is certified with ISO9001, ISO14001, OHSAS18001, SA8000, and others. We can provide mill test certificates and third-party inspection reports.Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 1 coil (approx. 3-10 tons). For trial orders, we can accommodate smaller quantities.Q: How long does delivery take?
A: Usually 15-30 days after deposit, depending on quantity and specifications. We ship from Tianjin, Shanghai, Qingdao, or Ningbo ports.Q: Can you supply coils equivalent to ASTM A36?
A: Yes, our Q235 grade is equivalent to ASTM A36. We also produce coils strictly to ASTM A36 standards.Q: What packaging do you use for export?
A: Coils are securely packed with steel strapping, wrapped in waterproof paper, and fitted with edge protectors to prevent damage during transit.
