JIS and EN Certified Tinplate Products with Comprehensive Mechanical Properties for Global Packaging Industries
2026/07/15
Meeting the Highest International Standards for Tinplate Packaging Materials
As a leading supplier of tinplate (SPTE) products, we take pride in delivering materials that meet the rigorous requirements of JIS and EN international standards. Our comprehensive range of tinplate sheets and coils combines exceptional mechanical performance with reliable corrosion protection, serving the diverse needs of the global packaging industry.
Understanding Tinplate: The Gold Standard for Metal Packaging
Tinplate consists of cold-rolled low-carbon steel sheets electroplated with commercial pure tin on both sides. The tin layer serves as a protective barrier against corrosion while maintaining the steel's inherent strength and formability. This unique combination makes tinplate the material of choice for food cans, beverage containers, aerosol products, chemical packaging, pharmaceutical containers, and cosmetic closures.
Comprehensive Mechanical Property Options
Our tinplate products are available across a full spectrum of temper grades, each engineered for specific forming and strength requirements:
| Temper Grade | Hardness (HR30Tm) | Yield Strength (MPa) | Typical Application |
|---|---|---|---|
| T-1 | 49±3 | 330 | Deep drawing, complex shapes |
| T-2 | 53±3 | 350 | Moderate drawing requirements |
| T-3 | 57±3 | 370 | General can bodies |
| T-4 | 61±3 | 415 | Can ends and closures |
| T-5 | 65±3 | 450 | Stiff can bodies, crowns |
| T-6 | 70±3 | 530 | High-strength applications |
| DR-7M | 71±5 | 520 | Double-reduced, beverage can ends |
| DR-8 / DR-8M | 73±5 | 550 / 580 | Beverage can bodies & ends |
| DR-9 / DR-9M | 76–77±5 | 620 / 660 | Ultra-thin, high-strength cans |
Precision Coating Weight Control
We offer a full range of tin coating weights from 1.1 g/m² to 11.2 g/m², with differential coating options available for specialized applications. Each coating designation is verified against minimum average coating weight standards to ensure consistent protection:
- Light Coatings (1.1–2.8 g/m²): Suitable for general packaging with moderate corrosion protection needs.
- Medium Coatings (5.6 g/m²): Ideal for food cans requiring reliable barrier properties.
- Heavy Coatings (8.4–11.2 g/m²): Recommended for aggressive contents, acidic foods, and extended shelf-life applications.
- Differential Coatings: Custom combinations available (e.g., 2.8/5.6, 5.6/8.4 g/m²) to optimize cost and performance.
