Tin plated steel sheet, commonly known as tinplate steel, refers to a cold-rolled thin steel plate coated with a thin layer of metal tin on the surface. It has a certain strength and hardness, good formability, and easy welding ability. The tin layer is non-toxic and tasteless, and the surface is bright. Tin mainly plays a role in preventing corrosion and rust. According to the production process, steels are divided into hot-dip tin plated steel sheets and electro-tin plated steel sheets.
