Shandong Sino Steel Co., Ltd. is a professional manufacturer of high-quality tinplate sheets, specializing in electrolytic tin coating for the canning industry. With a factory size of 10,000–30,000 square meters and an annual export value of US$2.5–5 million, we supply reliable, cost-effective thickness 0.15mm–0.50mm tinplate sheets to global markets. Our products are designed to meet the rigorous demands of food and beverage canning, ensuring excellent corrosion resistance, formability, and solderability.
Product Overview
Our electrolytic tinplate sheets are manufactured from high-grade cold-rolled steel substrate, coated with a uniform layer of pure tin via an electrolytic process. The thickness range of 0.15mm to 0.50mm makes them suitable for a wide variety of can sizes and applications—from small tuna cans to large paint cans. The tin coating provides a protective barrier against corrosion, while also offering a bright, attractive surface for printing and labeling.
Key Features & Technical Specifications
- Precise Thickness Control: Manufacturing tolerance within ±0.01mm, ensuring consistent performance in high-speed canning lines.
- Uniform Tin Coating: Electrolytic process guarantees even coating thickness (available from 1.0g/m² to 11.2g/m² per side), preventing pinholes and corrosion.
- Excellent Formability: Suitable for deep drawing, flanging, and seaming without cracking or delamination.
- Superior Solderability & Weldability: Ideal for traditional soldered cans or modern resistance welding processes.
- Surface Finish Options: Bright (B), Stone (S), or Matte (M) finishes to meet different aesthetic and functional requirements.
- Customizable Dimensions: Width from 600mm to 1050mm, coil or sheet form, with or without edge trim.
- Hardness Grades: T2, T2.5, T3, T4, T5 available, matching the stiffness needed for various can types.
- Environmental Compliance: Tin coating is food-safe and complies with international food packaging regulations.
