0.2mm 2.8/2.8g/m² Electrolytic Tin Plate (SPTE) Coils/Sheets for Durable Paint & Chemical Cans

This specialized Electrolytic Tin Plate (ETP) is engineered to meet the robust demands of industrial packaging, particularly for paint cans and chemical containers. With a precise 0.2mm thickness and a standard 2.8/2.8 g/m² tin coating on both sides, it offers an optimal balance of material economy and structural integrity. The tin layer provides a crucial, sacrificial barrier against corrosion, protecting the steel substrate from the often aggressive solvents and compounds found in paints, varnishes, and industrial chemicals. Available in both SPTE (tinplate) and TFS (Tin-Free Steel) variants, and supplied in coil or sheet form, this material is the reliable foundation for manufacturing two-piece, three-piece, and drawn-and-ironed (DI) cans that require durability, excellent sealing, and resistance to internal pressure or corrosive contents.

• Optimized Industrial Specification: The 0.2mm gauge provides sturdy walls for industrial cans, while the 2.8/2.8 g/m² coating offers cost-effective, reliable corrosion protection.

• Superior Corrosion & Chemical Resistance: The electrolytic tin coating acts as a robust barrier, significantly slowing down rust formation and resisting attack from many chemical agents found in paints and industrial products.

• Excellent Formability & Strength: Available in various tempers like DR8, T3, T4, and T5, it provides the necessary formability for deep drawing can bodies and the high strength (e.g., TS245, TS275 hardness) required for secure lids and handling.

• Versatile Surface for Finishing: Offered in Bright, Stone, Silver, and Matte finishes, the surface is ideal for high-quality direct printing or painting, allowing for strong branding and product information directly on the can.

• Broad Application Compatibility: While ideal for paint and chemical cans, its properties also make it suitable for robust food cans (sardine, tuna) and aerosol containers, offering manufacturing flexibility.

Choosing this purpose-built tinplate enhances the reliability and professional appearance of your industrial packaging. Its proven corrosion resistance extends product shelf life and prevents container failure. The material's consistent quality ensures high runnability on production lines, reducing waste. The ability to print directly onto the can creates a premium, tamper-evident package. Furthermore, offering both SPTE and TFS options allows customers to select based on their specific fabrication process (welding vs. soldering) and cost considerations.

Q1: Is this 0.2mm tinplate strong enough for 1-liter or gallon paint cans?
A1: Yes, the 0.2mm thickness, combined with appropriate temper grades like DR8 or T4/T5, provides ample strength and rigidity for larger format cans, including 1-liter and gallon sizes, ensuring they withstand filling, sealing, and transportation.

Q2: How does it resist corrosion from paint solvents?
A2: The tin coating provides a protective barrier. For highly aggressive solvents, the tinplate serves as an excellent substrate for additional internal epoxy or phenolic lacquers, which are specifically formulated to resist chemical attack and prevent interaction with the can's contents.

Q3: Can we order this material with pre-printed company logos for our paint cans?
A3: Absolutely. We offer high-quality lithographic printing services. You can supply your artwork, and we can deliver printed sheets or coils ready for fabrication, streamlining your production process and ensuring brand consistency.

Q4: What is the difference between using this for paint cans versus food cans?
A4: The base material can be similar. The key difference often lies in the internal lacquer applied during can making. Paint cans use chemical-resistant lacquers, while food cans use food-grade lacquers. Our tinplate is a versatile substrate suitable for both end-uses.

Q5: What is your quality assurance process?
A5: We conduct strict quality checks throughout production. Each batch is accompanied by relevant certifications (like SGS) and our Mill Test Certificate, which details the chemical composition, mechanical properties, coating weight, and dimensions to ensure it meets your specifications.
