Comprehensive Guide to Tinplate Coil

Tinplate, also known as electrolytic tinplate, refers to cold-rolled low-carbon thin steel sheets coated with commercial pure tin on both sides. This coating primarily functions to prevent corrosion and rust. The combination of steel’s rigidity and moldability with tin’s corrosion-resistant properties results in a material that is not only strong but also highly malleable. Tinplate is widely used in various manufacturing processes and industries, particularly in packaging, construction, and domestic appliances.
