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

Discover high-quality tinplate coils from a leading China supplier and factory. Our tinplate coils are cold-rolled steel that has been electrolytically coated with pure tin (Sn ≥99.9%) using advanced Ferrostan technology in sulfuric acid baths. We ensure compliance with FDA regulations while applying differential coatings ranging from 1.1 to 11.2 g/m², achieving a thickness of 0.15 to 1.50 μm with a remarkable porosity of less than 8 pores/cm². After the tinning process, each coil undergoes induction melting at temperatures between 240 and 260°C, creating durable FeSn₂ alloy layers that enhance solderability. Our ISO 11949 DR8-DR12 grades are meticulously controlled, featuring a 24-hour aging process at 150°C to guarantee exceptional mechanical properties.
