Shandong Sino Steel Co., Ltd., a professional manufacturer established in 2018 with a factory spanning 10,000-30,000 square meters, proudly presents our high-quality Tinplate Sheet 0.28mm, T5 Temper, 2.8/5.6g/m² Differential Coating. This product is engineered for demanding industrial applications where precise corrosion resistance, formability, and consistent coating distribution are critical. Leveraging advanced cold rolling and electrolytic tinning lines, we ensure every sheet meets strict dimensional and mechanical standards, supporting your production with reliable performance.
Our tinplate is produced from prime MR steel with a controlled 0.28mm thickness and T5 temper, offering an optimal balance of strength and ductility for deep drawing and bending operations. The differential coating – 2.8 g/m² on one side and 5.6 g/m² on the other – provides tailored protection: the heavier side resists internal corrosion while the lighter side facilitates soldering or painting. Available in customizable widths and lengths, this sheet is ideal for containers, drums, battery casings, and other industrial components.
We serve global markets including North America, South America, Europe, Africa, and Asia, with annual export value exceeding US$2.5 million. Our ISO9000 and ISO19011:2000 certifications underline our commitment to quality management and continuous improvement. Below you will find detailed specifications, technical benefits, and answers to common questions to help you evaluate this product for your needs.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between differential coating and equal coating?
A: Differential coating means two different tin weights on opposite sides of the sheet. This offers flexibility: the heavier side protects against corrosion, while the lighter side improves solderability or paint adhesion. Equal coating has the same weight on both sides. -
Q: Can you supply sheets larger than 1050mm width?
A: Yes, we can produce widths up to 1200mm upon request. Please contact our sales team with your exact requirements to confirm availability. -
Q: Is this tinplate suitable for food contact?
A: Yes, our tinplate is made from food-grade MR steel and complies with international standards for food packaging. We can provide a compliance certificate if needed. -
Q: What is the minimum order quantity (MOQ)?
A: Typically, our MOQ is 20 metric tons per size. However, for trial orders or sample requirements, we can accommodate smaller quantities. Please inquire. -
Q: How is the coating weight measured and verified?
A: We use coulometric method according to ASTM B545 to measure tin coating weight on each side. A mill test certificate is issued with each shipment. -
Q: Do you offer both bright and matte surface finishes?
A: Yes, both finishes are available. Bright finish is standard for decorative applications, while matte finish is preferred for printing or lacquering. Please specify your preference. -
Q: What is the lead time for a standard order?
A: Lead time varies by order size and customization. Typically 15-25 days after receipt of down payment. We can expedite for urgent orders. -
Q: Can you provide samples for testing before bulk order?
A: Absolutely. We offer free samples (you pay shipping) for qualification. Please contact us with your shipping details.
