Shandong Sino New Material Co., Ltd., a professional manufacturer established in 2018, proudly presents our Prime Tinplate Steel Coil with thickness ranging from 0.18mm to 0.30mm, T4 temper, and a differential tin coating of 5.6g/m² on one side and 2.8g/m² on the other. This product is engineered to meet the rigorous demands of the packaging industry, offering exceptional corrosion resistance, formability, and weldability. With an overseas office and a factory spanning 10,000–30,000 square meters, we ensure stable supply and consistent quality for global buyers.
Our tinplate coil is produced using advanced electrolytic timing lines and strict quality control systems certified under ISO9000 and ISO19011:2000. The T4 temper provides an optimal balance of hardness and ductility, making it ideal for deep drawing and stamping applications. The differential coating design allows cost-effective use in applications where one side requires higher corrosion protection than the other, such as food can ends or aerosol caps.
Key Features & Technical Specifications:
- Thickness Range: 0.18mm – 0.30mm (precision controlled within ±0.01mm)
- Temper Grade: T4 (Rockwell hardness HR30T 58–64), suitable for moderate forming
- Differential Tin Coating: 5.6g/m² (top) + 2.8g/m² (bottom) per ASTM A624 / JIS G3303 standards
- Width Options: Standard widths from 600mm to 1050mm; custom widths available upon request
- Coil Weight: Typically 3–8 tons per coil for efficient handling
- Surface Quality: Smooth, free from oil stains, scratches, and edge burrs
- Passivation: Available with chemical passivation (chromium oxide or chromium-free) for enhanced storage stability
- Edge Trim: Well-trimmed edges to prevent slitting damage

| Coil Weight | 3 – 8 tons | Pallet weight negotiable |
Advantages for Customers:
The differential tin coating design (5.6/2.8g/m²) offers a cost-effective solution for applications like can ends, where one side requires higher corrosion protection (e.g., food contact) and the other side only needs moderate protection. The T4 temper ensures excellent drawability without cracking, reducing production waste. Our coils are tightly wound with consistent tension to ensure smooth unwinding during slitting or stamping processes. All products are packed with moisture-proof paper and steel sheet protection to withstand long sea voyages.
Additionally, we provide flexible customization options including width, coil weight, and passivation type to match your specific production needs. With an annual export value exceeding US$2.5 million and shipments to markets across North America, South America, Europe, Asia, and Africa, Shandong Sino New Material has built a reputation for reliable quality and on-time delivery.
Backed by a skilled workforce of 101–200 employees and ISO-certified quality management systems, every coil is tested for thickness uniformity, tin coating adhesion, and surface finish. Our main ports of shipment – Qingdao, Tianjin, and Shanghai – ensure efficient logistics to global destinations. Whether you need standard sizes or a customized specification, our team is ready to support you with technical advice and competitive pricing.
Frequently Asked Questions (FAQ):
-
What is the minimum order quantity (MOQ)?
Our MOQ for prime tinplate coil is typically 20 metric tons per specification. Smaller trial orders can be negotiated for new clients. -
What is the lead time for production?
Standard lead time is 15–25 days after receipt of deposit, depending on order volume and coating requirements. -
Do you provide free samples?
Yes, we offer free samples (1–3 kg) for quality evaluation. The buyer pays the shipping cost. -
Can the tin coating be made equal on both sides?
Absolutely. In addition to the differential 5.6/2.8 combination, we supply equal coating (e.g., 2.8/2.8, 5.6/5.6) and other differential ratios upon request. -
What standards do your tinplate coils comply with?
We follow ASTM A624/A624M, JIS G3303, or GB/T 2520 standards. Your specific standard can be discussed. -
How is the coil packaged to prevent rust during shipping?
Each coil is wrapped with anti-corrosion VCI paper, plastic film, and steel strapping. A seaworthy wooden pallet or steel crate is used for export. -
Is it suitable for making food cans that require high hygiene?
Yes, the tin coating is food-grade and complies with international food contact safety regulations. We can provide relevant certificates if required. -
Do you offer after-sales technical support?
Certainly. Our technical team can provide guidance on stamping parameters, welding conditions, or downstream processing. We also welcome factory audits.
