Tinplate is the common name of electroplated tin sheet, abbreviated as spte. It refers to cold-rolled low-carbon sheet or steel strip coated with commercial pure tin on both sides, also known as tinned iron. Tin is mainly used to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, soldering and beautiful appearance of tin. It has the properties of corrosion resistance, non-toxic, high strength and good ductility. In the early days, tinplate was called tin plate. Because China's first batch of tinplate was imported from Macao in the middle of the Qing Dynasty, Macao transliterated "Makou" at that time, so it is generally called "tinplate" by Chinese people
