High-Quality Corrosion-Resistant Tinplate Coil from China Suppliers and Factory - FDA Compliant and Durable

Tinplate coils from our factory are expertly manufactured using cold-rolled steel, which is electrolytically coated with high-purity tin (Sn ≥ 99.9%) in sulfuric acid baths. As a leading supplier in China, we ensure that our FDA-compliant process applies differential coatings ranging from 1.1 to 11.2 g/m² with Ferrostan technology, achieving a precise thickness of 0.15 to 1.50 μm and maintaining porosity levels below 8 pores/cm². After the tinning process, our coils are subjected to induction melting at temperatures between 240 and 260°C, creating FeSn₂ alloy layers that enhance solderability. We offer ISO 11949 DR8-DR12 grades with controlled aging (24 hours at 150°C) to ensure the stability of mechanical properties, making our tinplate coils the ideal choice for various applications
