High-Quality Corrosion-Resistant Tinplate Coil Suppliers and Factory in China for Reliable Packaging Solutions

Tinplate coils from our factory are expertly crafted using cold-rolled steel coated with high-purity tin (Sn ≥ 99.9%) through an efficient electrolytic process in sulfuric acid baths. As a leading supplier in China, we utilize advanced Ferrostan technology to achieve differential coatings ranging from 1.1 to 11.2 g/m², with a precise thickness of 0.15 to 1.50 µm and excellent porosity of less than 8 pores/cm². After the tinning process, our coils experience induction melting at temperatures between 240 and 260°C, creating durable FeSn₂ alloy layers that enhance solderability. Our ISO 11949 DR8-DR12 grades undergo controlled aging for 24 hours at 150°C, ensuring stable mechanical properties and top-notch performance.
