Key Features & Technical Specifications
- Precise thickness control: Every sheet is gauged within tight tolerances (±0.01 mm) to guarantee uniform material for lid forming.
- Excellent formability: With a temper range of T3 to T5 (optional), our tinplate offers the right balance of hardness and ductility for complex can lid profiles without cracking.
- Food-safe coating: The tin coating provides superior corrosion resistance and meets international food contact safety standards; passivated or unpassivated options are available.
- Clean surface quality: Secondary grade sheets are selected to minimize pinholes and surface defects, ensuring smooth lid edges and reliable sealing.
- Custom dimensions: Widths from 600 mm to 1050 mm, and coils or cut sheets can be produced to your exact specifications.
- Reliable supply chain: Our annual export value of US$2.5–5 million reflects stable production capacity and timely delivery from Qingdao/Tianjin/Shanghai ports.

Frequently Asked Questions
-
Is this secondary tinplate suitable for direct food contact?
Yes, when passivated and coated appropriately, our secondary tinplate meets general food safety standards. We recommend verifying compatibility with your end-use regulations. -
What is the typical thickness tolerance?
The thickness tolerance is ±0.01 mm for the stated range, ensuring consistent feeding in high-speed presses. -
Can you provide custom width or coil dimensions?
Absolutely. We offer custom slitting and shearing services; minimum order quantity is typically 5 tons for custom sizes. -
How does secondary tinplate differ from primary tinplate?
Secondary material may have minor cosmetic imperfections (e.g., light scratches, staining) but maintains the same mechanical and corrosion-resistant properties. It is ideal for lids where the exterior appearance is less critical. -
What packaging is used for export?
We use wooden pallets, steel strapping, and waterproof wrapping. Each bundle is labeled with grade, thickness, and lot number. -
Do you provide certificates of analysis or mill test reports?
Yes, we supply Material Test Certificates (MTC) or Certificate of Compliance per ISO requirements upon request. -
What is the lead time for trial orders?
For stock items, lead time is 7–10 days. For custom dimensions, it is 15–20 days after order confirmation. -
Can this tinplate be lacquered after forming?
Our tinplate surface is compatible with standard epoxyphenolic and oleoresinous lacquers. We recommend a pre-production test for adhesion.
