Product Overview
This electrolytic tinplate sheet features a uniform tin coating of 2.8 g/m² on each side (total 5.6 g/m²), providing optimal protection against corrosion while maintaining excellent solderability and printability. Specifically engineered for aerosol can manufacturing, the material offers the right balance of strength, formability, and surface finish to withstand high internal pressures and aggressive chemical contents. Available in multiple tempers and surface finishes, our tinplate can be customized to meet your specific can-making requirements.
Key Features & Benefits
Precise Tin Coating: 2.8/2.8 g/m² electrolytic coating ensures consistent protection against rust and interaction with product contents.
Superior Weldability: Low contact resistance and excellent seam welding performance for high-speed can production lines.
Excellent Printability: Smooth surface accepts high-quality lithographic printing, labeling, and varnishing without defects.
Good Formability: Suitable for deep drawing, necking, and flanging operations required for aerosol can bodies and ends.
Custom Dimensions: Thickness from 0.15 mm to 0.50 mm and width from 750 mm to 1050 mm, cut to your required sheet size.
Strict Quality Control: ISO9000 certified process with in-line inspection for coating weight, thickness, and surface defects.

Applications in Aerosol Can Manufacturing
Our electrolytic tinplate is specifically formulated for the demanding requirements of aerosol cans. The 2.8/2.8 g/m² tin coating delivers:
• High resistance to corrosive propellants and product formulations (e.g., deodorants, paints, insecticides).
• Reliable double-seam integrity and flange formation.
• Compatibility with high-speed filling lines and crimping processes.
• Consistent dome and cone profiles for pressure resistance up to 1.8 MPa (depending on design).
• Excellent shelf life – the tin coating acts as a sacrificial anode protecting the steel substrate.

Frequently Asked Questions (FAQ)
1. What does “2.8/2.8 g/m² tin coating” mean exactly?
It means each side of the steel sheet has a tin coating weight of 2.8 grams per square meter. The total tin on both sides is 5.6 g/m². This balanced coating provides uniform corrosion protection and excellent solderability for aerosol cans.
2. Is this tinplate suitable for food-grade aerosol cans (e.g., whipping cream)?
Yes. The tin coating is non-toxic and complies with general food contact material standards. However, for specific food safety regulations (e.g., FDA, EU 1935/2004), we recommend requesting our material compliance certificate and testing reports. Our ISO9000 system ensures traceability and quality control.
3. What are the available sheet sizes and packaging options?
We offer thicknesses from 0.15 mm to 0.50 mm and widths from 750 mm to 1050 mm. Sheet length can be customized from 500 mm to 1100 mm. Standard packaging is in wooden pallets with steel strapping, or as per customer requirements (moisture-proof paper, shrink wrap, etc.).
4. Can I get a small sample for trial before placing a bulk order?
Absolutely. We provide free samples (FOB basis, customer pays freight) in A4 size or your specified dimensions. Samples are usually shipped within 7 working days after confirmation.
5. What is the minimum order quantity (MOQ)?
The typical MOQ is 20 metric tons per specification. For first-time trial orders, we may accept 10 tons. Please contact your regional sales representative for flexibility.
6. How long does delivery take after order confirmation?
Standard production lead time is 15–25 days from receipt of deposit and final specification approval. For large orders (over 100 tons), please allow 25–35 days. Delivery is via Qingdao, Tianjin, or Shanghai ports.
7. Do you provide any quality documents with the shipment?
Yes. Each shipment includes a Mill Test Certificate (MTC) showing chemical composition, mechanical properties, and tin coating weight test results. We also provide ISO9000 compliance documentation upon request.
8. What is the difference between your tinplate and tin-free steel (TFS / ECCS)?
Tinplate uses a tin coating (metallic tin) which offers excellent solderability, high corrosion resistance, and good appearance. TFS uses a chromium/chrome oxide layer – it has lower cost but poorer solderability and corrosion resistance. For aerosol cans requiring strong seam integrity and long shelf life, tinplate is the preferred choice.
