Tinplate, also known as tinned iron, is the common name of tinned steel plate, abbreviated as SPTE in English, which refers to cold-rolled low-carbon steel plate or steel strip with commercial pure tin on both sides. Tin mainly plays an anti-corrosion and anti-rust role. It combines the strength and formability of steel with the corrosion resistance, weldability and aesthetics of tin, and has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.

Tinplate is an iron sheet with a layer of tin on its surface, which is not easy to rust. It is also called tinned iron. This coated steel plate has been called "tinplate" for a long time in China. Some people think it is called "tinplate" because tinplate used to make cans is imported from Macao (the English name Macao can be pronounced "tin plate"). There are other sayings. For example, China used to use this tinplate to make kerosene lamp caps, which were shaped like tinplates, so they were called "tinplates". The name "tinplate" is not exact, so it was renamed as tinplate at the China tinplate conference in 1973, and the name "tinplate" was no longer used in official documents.
