Goldsupplier Tests Store is proud to offer 0.18mm-0.50mm Thickness Tinplate Coils MR Type Soft Temper for Deep Drawing, manufactured in strict compliance with JIS G3303 standards. As a dedicated manufacturer located in Dongying, Shandong, China, we leverage our 1,000-3,000 sqm factory and 11-50 experienced professionals to produce high-quality tinplate coils suitable for demanding deep drawing applications. Our product features excellent formability and consistent mechanical properties, making it the ideal choice for producing food cans, aerosol cans, battery cases, and other drawn containers. With annual export value exceeding US$1 million and a strong presence in North America, South America, Africa, and Oceania, we are committed to delivering reliable steel packaging solutions that meet global quality expectations.
Our tinplate coils are manufactured using MR type low residual steel, which ensures superior corrosion resistance and uniform tin coating adhesion. The soft temper (T1-T2) provides excellent ductility, allowing the material to undergo severe deformation without cracking or thinning. Whether you require bright or matte surface finish, or specific coil dimensions, we can customize the product to match your production needs. Below is a detailed overview of the key specifications and benefits.
Key Product Features & Benefits
- Precise Thickness Control: Available in a range of 0.18mm to 0.50mm with tight tolerances (±0.005mm), ensuring consistent material flow during deep drawing.
- Soft Temper for Deep Drawing: The T1-T2 temper grade guarantees high elongation and low yield strength, minimizing tool wear and reducing the risk of die cracks.
- MR Type Low Residual Steel: Superior chemical composition (low copper, nickel, chromium) prevents rapid corrosion and maintains product integrity over long shelf life.
- JIS G3303 Compliance: Full adherence to Japanese Industrial Standard for tinplate, ensuring dimensional accuracy, mechanical properties, and coating uniformity.
- Customizable Coil Parameters: Width from 600mm to 1050mm, inner diameter options (508mm or 610mm), and tin coating weights from 2.8g/m² to 11.2g/m² per side.
- Surface Finish Options: Choose bright finish for high gloss appearance or matte finish for improved adhesion of printing inks and lacquers.
- Excellent Edge Quality: Precision slitting and edge trimming eliminate burrs, reducing the risk of scratching during forming and subsequent handling.
- Consistent Mechanical Properties: Every coil is tested for hardness, tensile strength, and drawability to ensure repeatable performance in high-speed stamping presses.

Why Choose Our Tinplate Coils?
Our tinplate coils are specifically engineered for deep drawing operations where material consistency and surface quality are critical. The combination of MR type steel and soft temper allows the material to be stretched and formed into complex shapes without tearing. This reduces downtime and scrap rates, ultimately lowering your production costs. Additionally, the precise tin coating protects the steel from corrosion and ensures compatibility with food-grade lacquers and printing inks, making it suitable for the food packaging industry.
We understand that each customer has unique requirements. That’s why we offer flexible customization in width, inner diameter, coating weight, and surface finish. Our team works closely with you to match your exact specifications, and we can provide small trial coils for testing before full-scale production. With a lead time of 15-25 days after order confirmation, and shipment from Tianjin port, we ensure timely delivery to North America, South America, Africa, and Oceania.
Frequently Asked Questions (FAQ)
Q1: What is the difference between MR and L type tinplate?
A: MR type has lower residual elements (Cu, Ni, Cr) compared to L type, providing better corrosion resistance and tin coating adhesion. It is recommended for deep drawing applications where high formability is required.
Q2: Can you supply coils with different surface finishes?
A: Yes, we offer both bright finish (Stone finish) and matte finish (Satin finish). Bright finish provides a glossy appearance, while matte finish improves ink and lacquer adhesion. Please specify your preference when ordering.
Q3: What is the typical lead time for a standard order?
A: For standard thicknesses and widths, the lead time is approximately 15-20 days. For customized specifications, it may extend to 20-25 days. We can expedite for urgent orders upon request.
Q4: Do you provide samples for testing?
A: Yes, we can provide small sample coils (e.g., 100-200 kg) for pre-production trials. The sample cost is negotiable, and shipping is at the customer's expense.
Q5: How do you ensure the thickness tolerance is maintained?
A: Our production line is equipped with automatic thickness gauges that continuously monitor the strip. Online feedback control adjusts the rolling mill to maintain tolerance within ±0.005mm.
Q6: Is your tinplate suitable for food contact?
A: Yes, our tinplate coils meet the requirements of food-grade packaging. The tin coating is non-toxic and complies with international food safety regulations. We also hold HACCP certification, ensuring safe handling throughout production.
Q7: What is the maximum coil weight you can produce?
A: The maximum coil weight is typically 10-12 tons, depending on the width and thickness. For heavier coils, please consult our sales team for feasibility.
Q8: Do you offer any quality inspection reports?
A: Absolutely. We provide a mill test certificate (MTC) with every shipment, detailing chemical composition, mechanical properties, coating weight, and dimensional results. Third-party inspection is also welcome.
