Tinplate refers to the surface of the steel plate coated with a thin layer of metal tin. Tinplate is the low carbon steel rolled into about 2mm thick steel plate, after pickling, cold rolling, electrolytic cleaning annealing,leveling, edge cutting processing, and then after cleaning, electroplating, softening, passivation treatment, oiling after cutting into tinplate plate finished products.

Tinplate(SPTE) is a common name for electroplated tin steel sheets, which refers to cold-rolled low-carbon steel sheets or strips coated with commercially pure tin on both sides. Tin mainly acts to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability, and aesthetic appearance of tin in a material with corrosion resistance, non-toxicity, high strength, and good ductility. Tinplate packaging has a wide range of coverage in the packaging industry because of its good sealing, preservation, light-proof, ruggedness, and unique metal decoration charm.
