Overview
What This Material Is For
Tinplate coil is a cold-rolled steel strip with a tin coating applied to both sides, providing corrosion resistance and a smooth, printable surface. It is used where food safety, packaging integrity and visual appeal are critical. Jialu Metal stocks tinplate coil across multiple international standards, so a project requiring GB/T 2520, JIS G3303 or DIN EN 10203 material does not need to be split across different mills or suppliers. Coils are available in a range of thicknesses, widths, coating levels and temper grades, all from one supplier with one inspection and one shipment.

Honest comparison
How It Compares With The Alternatives
| Galvanized steel coil | Galvanized steel is cheaper and suitable for non-food packaging; tinplate offers better corrosion resistance, printability and food safety compliance for cans and packaging |
|---|---|
| Aluminum coil | Aluminum is lighter and more corrosion-resistant but more expensive and less formable; tinplate offers better cost-performance for high-volume can-making |
| Untreated cold-rolled steel | Untreated steel is cheaper but prone to rust; tinplate provides a protective layer and printable surface, reducing the need for additional coatings |
How to specify it
Buying Guide
- Start with the application: food, chemical, aerosol or decorative packaging, to select the required coating level and surface finish
- Specify the temper grade (e.g. DR7M, T4) based on the forming process and required hardness
- Provide the coil size (thickness, width, ID) and weight range to ensure compatibility with your machinery
- State the standard (GB/T, JIS, DIN, ASTM) to ensure compliance with destination market regulations
- Request third-party inspection at order stage to align with your quality schedule
