Welcome to Hemaokang Steel (Shandong) Co., Ltd., a professional manufacturer of cold rolled carbon steel coils located in Liaocheng, Shandong, China. Our cold rolled carbon steel coil is available in Q195, Q235 and Q355 grades, with thickness from 0.3mm to 2.0mm, surface oiled and matte finish, designed specifically for stamping applications. With a dedicated production team and advanced rolling technology, we deliver coils that offer consistent mechanical properties, stable surface quality, and high dimensional accuracy, ensuring smooth and efficient stamping operations. This product is a reliable choice for manufacturers in automotive, appliance, and general metalworking industries.
The cold rolled coil is produced through a precise cold rolling process that reduces the thickness of hot rolled steel and improves its surface finish and flatness. The matte finish is achieved by controlled roll surface texture, providing an ideal substrate for stamping and forming operations. This product configuration is particularly recommended for progressive die stamping, deep drawing, bending, and other forming processes where uniform thickness and surface lubricant retention are critical. In addition, the oiled surface provides temporary rust protection, making it suitable for storage and transportation before further processing.
- Multiple grades available: Q195 offers good ductility, Q235 provides balanced strength and formability, and Q355 supplies higher strength for structural stamping components.
- Thickness range: 0.3 mm to 2.0 mm, covering common stamping material requirements.
- Oiled matte surface: improves drawing and stamping performance while preventing oxidation.
- High flatness and uniform thickness: reduces die wear and improves product consistency.
- Customizable width and packing: meet different production needs.

Material and Performance Advantages:
The cold rolled carbon steel coil from Hemaokang Steel is manufactured with strict control to achieve consistent performance in stamping. The low carbon content of Q195 and Q235 grades ensures softness and good elongation, making them suitable for bending and deep drawing. Q355 offers an upgraded mechanical strength for components requiring higher load-bearing capacity. During the cold rolling process, the steel is hardened by mechanical deformation, then further treated to restore ductility and maintain a stable microstructure. As a result, the coils deliver consistent hardness and tensile strength throughout the entire length, which greatly reduces the variation of springback in stamped parts. The oiled matte finish creates a fine surface profile that holds preset lubricant films, forming a barrier between the workpiece and the die. This reduces friction, scratching, and material pickup, thus prolonging die life and improving the surface quality of finished parts.
Benefits for Your Production:
- Increased tool life: The uniform thickness and controlled surface texture reduce abrasive wear on stamping dies.
- Less downtime: Consistent coil quality minimizes adjustments and interruptions during production.
- Cost reduction: High yield and low rejection rates reduce overall material consumption.
- Design flexibility: Available grades and thicknesses allow you to choose the optimal material for each application.
- Supply reliability: We maintain stable production capacity and timely delivery to support your procurement schedule.

Frequently Asked Questions:
Q1: What steel grades are available for this coil? A: We supply Q195, Q235, and Q355 as standard. Q195 has the highest ductility, Q235 is general purpose, and Q355 provides higher strength. Other equivalent grades can be produced upon request.
Q2: What thickness range can I order? A: The standard thickness is 0.3 mm to 2.0 mm. Thickness outside this range may be available for special orders, subject to rolling schedule and minimum quantity.
Q3: Why is matte finish important for stamping? A: Matte finish creates a micro-surface profile that holds lubricant during stamping, which reduces friction and prevents adhesion between the sheet and the die. It also provides a better base for later painting or coating compared to high-gloss surfaces.
Q4: Can you supply slit coils or cut-to-length sheets? A: Yes. We can provide slit coil, cut-to-length sheets, or custom blanks according to your dimensions. Please contact us with your exact specifications.
Q5: What is the typical coil weight and inner diameter? A: Usually the inner diameter is 508 mm or 610 mm, and the coil weight ranges from 3 to 8 tons. Specific packing can be adjusted to match your handling equipment.
Q6: How do you guarantee quality? A: We are certified under ISO9001. Each batch is tested for chemical composition, mechanical properties, thickness, and surface quality. Test certificates are available upon request.
Q7: Is the oiled surface acceptable for welding? A: For most stamping and welding processes, the lightweight oil film is acceptable. For sensitive applications, you can specify low-oil or dry finish, or degrease the material before welding.
Q8: What are the intended applications? A: This coil is ideal for automotive stampings, electrical enclosures, metal furniture, steel doors and windows, hardware parts, and general cold bending profiles. It can also be used for simple structural components where higher strength Q355 is required.
