Tinplate is the common name for electro-tinned thin steel plate. The English abbreviation is SPTE, which refers to cold-rolled low-carbon thin steel plate or steel strip plated with commercial pure tin on both sides. Tin mainly plays a role in preventing corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in a single material. It has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.
Tinplate is an iron sheet with a layer of tin plated on the surface. It is not easy to rust and is also called tinplate. This kind of coated steel plate has been called “tinplate” in China for a long time. Some people think that because the tinplate used to make cans was imported from Macau (English name Macau can be read as horse mouth), it is called “tinplate”. There are also other sayings. For example, China used this kind of tin-plated sheet to make kerosene lamp caps, which were shaped like horse horns, so they were called “tinplate”. The name “tinplate” is not exact. Therefore, the name “tinplate” was no longer used in official documents at the China Tinplate Conference in 1973.
