0.2mm DR8 Deep-Draw Electrolytic Tin Plate Sheets with Paint-Ready Surface

This product is a specific grade of Electrolytic Tin Plate (ETP) engineered for demanding metal can fabrication. The defining specifications are its 0.2mm (medium-thin) thickness and the DR8 temper grade, which signifies excellent deep-drawing quality. This combination makes it particularly suitable for manufacturing small to medium-sized cans—such as those for beverages, food, and aerosols—that require complex shaping through multiple drawing operations. The sheet is coated with a consistent layer of pure tin via electrolysis, providing a robust, corrosion-resistant base. Crucially, the surface is supplied in a paint-ready condition (Bright, Stone, Matte, etc.), allowing for excellent adhesion of external decorative paints and internal protective lacquers. This creates a reliable, multi-layer "steel-tin-paint" composite structure ideal for durable and visually appealing packaging.

• Excellent Deep-Draw Performance (DR8): The DR8 temper indicates superior ductility and formability, allowing the material to undergo significant stretching and complex stamping without cracking or splitting, perfect for shaped cans.

• Optimized 0.2mm Gauge: Provides an ideal balance of material strength for can integrity and lightweight efficiency, reducing material costs while maintaining necessary rigidity.

• Superior Paint Adhesion: The prepared surface finish ensures that subsequent decorative and protective paint layers bond firmly, enhancing durability and aesthetic quality while preventing peeling.

• Inherent Corrosion Resistance: The electrolytic tin coating acts as a sacrificial barrier, protecting the steel substrate from rust and providing a foundation for enhanced chemical resistance when combined with appropriate lacquers.

• Versatile Application Scope: Designed for a wide range of containers including aerosol cans, food cans (tuna, sardines, vegetables, fruit), and paint cans, offering flexibility to manufacturers.

Selecting these 0.2mm DR8 sheets delivers precision and efficiency in can production. The guaranteed deep-draw capability reduces waste and downtime associated with material failure during forming. The paint-ready surface streamlines the finishing process, ensuring a high-quality final appearance. The material’s consistency ensures reliable performance in high-speed stamping and drawing presses. Furthermore, its compliance with food-grade standards (when using MR steel) makes it a safe choice for food and beverage packaging.

Q1: What does "DR8" mean, and why is it important?

A1: DR stands for "Draw Redraw" or "Deep Drawing." DR8 is a specific temper grade indicating the material has been processed to possess excellent elongation and formability. It is crucial for manufacturing cans that require deep, complex shapes without material failure.

Q2: Is the 0.2mm thickness strong enough for pressurized aerosol cans?

A2: Yes, when combined with the high-strength properties of the DR8 temper and proper can design engineering, 0.2mm tinplate provides sufficient strength and pressure resistance for many aerosol can applications.

Q3: Can these sheets be supplied with a pre-applied internal coating?

A3: We primarily supply the paint-ready base tinplate. However, we can coordinate with partner facilities to provide sheets with custom internal food-grade lacquers (e.g., epoxy) applied, based on your specific product requirements.

Q4: What is the difference between the paint-ready surface and a pre-painted surface?

A4: A paint-ready surface has been treated (e.g., passivated) to maximize adhesion for paint applied later by the can maker. A pre-painted sheet has the final decorative or protective paint already applied by the supplier. We offer the former for maximum flexibility.

Q5: What quality documentation is provided?

A5: We supply a Mill Test Certificate with each batch, verifying the chemical composition, mechanical properties (confirming DR8 temper), coating weight, and dimensions, ensuring the material meets your specified performance criteria.
