Audited Supplier Product Description
Tinplate coil is a general term for electroplated tin plate, which refers to a cold-rolled low-carbon steel sheet or strip coated with commercial pure tin on both sides. The main role of tin is to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, weldability and aesthetics of tin, resulting in a material that is corrosion resistant, non-toxic, high strength and good ductility.
