Key Product Features & Technical Specifications
- Precise Thickness & Width: 0.22mm thickness with ±0.005mm tolerance, and 900mm width with ±1mm tolerance, ensuring consistency in downstream processing.
- Bright Annealed (BA) Surface: The BA finish delivers a mirror-like, reflective surface that enhances printability and aesthetic appeal, while also reducing friction during can forming.
- Material Grade: Manufactured from low-carbon steel (MR grade or equivalent) with a pure tin coating. The coating weight can be customized to meet specific corrosion resistance requirements (e.g., 2.8/2.8 g/m², 5.6/5.6 g/m²).
- Excellent Formability: The tinplate exhibits superior ductility and elongation, allowing deep drawing, necking, and flanging without cracking or delamination.
- Food-Grade Safety: The tin coating is non-toxic and complies with international food contact material standards. Our production process is ISO9000 and ISO19011:2000 certified, ensuring rigorous quality control.
- Coil Packaging: Each coil is tightly wound, with inner diameter of 508mm (standard), wrapped in anti-rust paper, plastic film, and steel strapping for safe sea transport.

Frequently Asked Questions (FAQ)
Q1: Is this tinplate suitable for direct contact with acidic food?
A: Yes, the tin coating provides excellent resistance to mild acids commonly found in fruits and vegetables. However, for highly acidic contents, we recommend a higher coating weight or an additional lacquer layer. Please consult our technical team for specific recommendations.
Q2: What is the minimum order quantity (MOQ) for this product?
A: The standard MOQ is 20 tons per specification. For smaller trial orders, we can accommodate a minimum of 5 tons upon request. Please contact our sales team for details.
Q3: Can you provide samples for testing before bulk order?
A: Absolutely. We can provide free samples (A4 size sheets or small coil samples) with the customer covering shipping costs. Please allow 5-7 working days for sample preparation.
Q4: How does the BA finish differ from other surface finishes like stone finish or matte?
A: BA (Bright Annealed) finish is achieved by annealing in a controlled atmosphere, resulting in a reflective, mirror-like surface. It is smoother than stone finish, offering better printability and lower friction during can forming. Stone finish has a duller appearance and is often used for easy-open ends.
Q5: What is the typical lead time for this product?
A: For standard specifications, the lead time is approximately 15–20 days after order confirmation and deposit. Custom specifications may require 25–30 days. We can prioritize urgent orders based on production schedule.
Q6: Do you offer certificates of analysis (COA) with each shipment?
A: Yes, we provide a COA for every batch, detailing thickness, width, coating weight, temper, and surface quality test results. Our ISO-certified lab ensures accurate data.
Q7: Can this tinplate be used for both can bodies and ends?
A: Yes, the 0.22mm thickness is suitable for both can bodies and ends in many standard food can sizes. However, for ends requiring higher strength, a slightly thicker gauge (e.g., 0.24mm) may be recommended. Our technical team can help select the optimal thickness for your application.
Q8: How is the tinplate packaged for export?
A: Each coil is first wrapped with anti-rust paper, then sealed with PE film, followed by steel strapping and reinforced with wooden pallets or crates. The coils are securely stacked in containers to prevent movement. We also offer vacuum packaging for extra protection in humid environments.
