What is Tinplate? Core Definition & Huaxiao-Alloy’s Process
Tinplate refers to cold-rolled, low-carbon steel sheet coated with a thin layer of tin via electrolytic deposition (electrolytic tinplate, ETP) or hot-dipping (hot-dipped tinplate). Huaxiao-Alloy’s process ensures:
- Base Steel: Ultra-clean, low-carbon (0.01-0.13% C) steel for maximum ductility.
- Electroplating: Precision tin coating (0.1–2.0 g/m² per side) with chromate or oxide passivation.
- Oiling: Food-safe dioctyl sebacate (DOS) or acetyl tributyl citrate (ATBC) oils for corrosion resistance.
Key Properties:
- Food Safety: Meets FDA/EC1935 standards – ideal for canned foods/beverages.
- Solderability: Enables seamless can seam welding.
- Barrier Protection: Tin resists oxidation, sulfur staining, and acidic contents.

Coating Types & Applications
| Coating Weight (g/m²) | Type | Best For |
|---|---|---|
| 1.1–2.8 | Light Coat | Dry food, non-aggressive products |

| 5.6–11.2 | Heavy Coat | Acidic foods (tomato, citrus) |
Tinplate vs. Alternative Coated Steels: The Huaxiao Advantage
While tin plated steel sheet dominates food packaging, alternatives like TFS (Tin-Free Steel), ECCS (Electrolytic Chromium Coated Steel), and galvanized steel serve niche roles.
Performance Comparison Table
| Property | Huaxiao Tinplate | TFS (Cr/CrOx) | ECCS | Galvanized Steel |
|---|---|---|---|---|
| Corrosion Resistance | Excellent (Sn barrier) | Good (Cr barrier) | Very Good (Cr + epoxy) | Poor (Zn reacts with acids) |
| Solderability | Excellent | Poor (requires welding) | Poor | Poor |
| Printability | Excellent (inks adhere) | Good | Excellent | Fair |
| Food Safety | FDA-Compliant | FDA-Compliant | FDA-Compliant | Not for direct contact |
| Cost (per m²) | $$ | $ | $$$ | $ |
| Typical Use | Canned tuna, soup | Can ends, crowns | Beverage cans | Construction, ducts |
Key Takeaways:
- Tinplate is irreplaceable for soldered food cans requiring long shelf life.
- TFS is cheaper but limited to can ends/lids due to poor solderability.
- ECCS excels in beverage cans needing high print quality.
- Galvanized steel is unfit for food contact due to zinc migration.
Why Choose Huaxiao-Alloy Tinplate?
We solve critical packaging challenges with:
Precision Metallurgy
- Base steel hardness tailored to temper grades (T1-T5) for deep drawing (DRD cans) or rigidity (food trays).
- Consistent coating weights (±0.1 g/m²) via AI-controlled electroplating.
Sustainable Solutions
- Recyclable indefinitely (steel’s magnetic properties aid recovery).
- Thin coatings (≤1.5 µm) reduce tin usage by 40% vs. industry averages.
Formability Expertise
- DR-8 (DR550) grade for complex shapes (e.g., aerosol cones).
- DR-9 (DR620) for high-strength food cans.
Global Compliance
- Certifications: ISO 9001, ISO 22000, BRCGS Packaging.
- Traceability: Mill test reports with heat/coil numbers.

Pre-Painted Galvalume Steel Coil / Sheet / Plate
Huaxiao-Alloy’s Pre-Painted Galvalume® Steel combines 55% aluminum-zinc alloy substrate with precision-engineered polymer coatings – delivering 4-6x longer service life vs. standard PPGI.
Pre-Painted Galvanized Steel Coil / Sheet / Plate
Huaxiao-Alloy’s Pre-Painted Galvanized Steel combines dual-layer protection: a zinc-based metallic substrate (GI or GL) with advanced polymer coatings – engineered to withstand UV degradation, chemical exposure, and mechanical stress while maintaining color integrity for 20-40 years.
Galvalume Steel Coil / Sheet / Plate
Huaxiao-Alloy’s Galvalume® (55% Al-43.4% Zn-1.6% Si) delivers triple-defense corrosion resistance – combining aluminum’s barrier protection, zinc’s sacrificial cathodic action, and silicon’s alloy-layer control.
Zinc-Aluminum-Magnesium Coated Steel Coil / Sheet / Plate
Huaxiao-Alloy’s Zinc-Aluminum-Magnesium (ZAM) coating leverages a ternary alloy (Zn + 5-11% Al + 2-3% Mg) to deliver 10-15X superior corrosion resistance vs. traditional galvanized steel. The patented self-repairing mechanism forms dense protective films over scratches and cut edges – revolutionizing structural longevity in marine, automotive, and infrastructure projects.
Hot-Dip Aluminum Coated Steel Coil / Sheet / Plate
Huaxiao-Alloy’s Hot-Dip Aluminum Coating transforms carbon steel into an ultra-durable hybrid material that outperforms traditional galvanized steel 3-5x in extreme heat (≤800°C) and corrosive environments.
FAQs: Tinplate Sheet Essentials
None. “Tinplate,” “tinned plate,” and “tin plated steel sheet” refer to the same product – steel coated with tin.
Yes. Specify heavy coat tinplate (≥5.6 g/m²) for tomatoes, citrus, or vinegar-based products. Our passivation layer enhances acid resistance.
- Strength: Tinplate withstands higher pressure (ideal for carbonated drinks).
- Recyclability: Both are recyclable, but steel cans are magnetic for easier sorting.
- Cost: Tinplate is cheaper for high-volume production.
Tinplate withstands retort sterilization (121°C/250°F) but avoid prolonged >150°C/302°F exposure to prevent tin melting.
Both. We offer coils (ID: 508 mm/20″) or cut-to-size sheets (custom dimensions available).
- Recycled content: Up to 35% post-consumer steel.
- Thin coatings reduce tin mining impact.
- Water-based passivation avoids hexavalent chromium.
