As a trusted manufacturer since 2018, Shandong Sino Steel Co., Ltd. specializes in high-quality steel products. Our Electrolytic Tinplate Sheets 0.23mm Thickness, 900x1800mm Size, Passivation Treatment are engineered to meet the rigorous demands of packaging and industrial applications. With our ISO9000 certified production processes and factory spanning 10,000–30,000 square meters, we ensure every sheet delivers consistent thickness, excellent corrosion resistance, and superior formability.
These tinplate sheets are ideal for manufacturing food cans, aerosol containers, battery shells, and other deep-drawn products. The precise 0.23mm thickness and 900x1800mm dimension offer a perfect balance between strength and workability, while the passivation layer enhances rust protection and improves lacquer adhesion. Below, we detail the key attributes that make our product a reliable choice for global buyers.
Key Features & Benefits
- Precise Thickness Tolerance: ±0.005mm ensures uniform forming and stacking.
- Passivation Treatment: Chemical passivation (often dichromate or cathodic) provides a stable oxide layer, preventing tin oxidation and extending shelf life.
- Excellent Solderability & Weldability: Suitable for high-speed can seaming lines.
- Food-Grade Safety: Tin coating meets FDA and EU food contact standards (upon request).
- Customizable Supply: Available in different coating weights, temper grades, and edge trimming options.
