Frequently Asked Questions
1. What is the typical hardness range for your tinplate?
Our High Hardness Tinplate is specified as HR30T 60+. The actual hardness can be controlled within 60-65 HR30T upon request. We can also adjust the temper grade (T4, T5, T6) to meet your specific forming requirements.
2. Can this tinplate be used for alkaline battery shells as well?
Yes, the high hardness and corrosion resistance make it suitable for both lithium-ion and alkaline battery shells. However, we recommend testing samples under your specific process conditions. We can provide free samples for evaluation.
3. What is the minimum order quantity (MOQ)?
Our standard MOQ is 5 tons per size. For trial orders, we can accommodate smaller quantities (e.g., 1 ton) at a slightly higher price. Please contact our sales team for details.
4. Do you provide cutting or slitting services?
Yes, we offer slitting to narrower widths and cutting to sheets according to your specifications. Additional charges may apply. Please inquire when placing your order.
5. How do you guarantee the tin coating quality?
We use a hot-dip or electrolytic tinning process with strict control of coating weight (typically 2.8/2.8 g/m²). Each coil is tested for porosity, adhesion, and thickness uniformity. Our quality system is ISO9000 certified.
6. What packaging do you use for export?
Coils are packed with moisture-proof paper, plastic film, and steel strapping, then loaded into containers or onto wooden pallets. We also provide custom packaging (e.g., anti-rust VCI paper) upon request.
7. Can you supply certificates of origin or material test reports?
Yes, we can provide Certificate of Origin (COO), mill test certificate (MTC), and other documentation as required by your customs or quality department. Our ISO19011:2000 internal audit system ensures traceability.
8. What is the lead time for a standard order?
Typically 15-20 days after receiving the deposit. For urgent orders, we can expedite production to 10-12 days, subject to availability. Please confirm with our sales team.
