Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate.
Tinplate consists of sheets of steel, coated with a thin layer of tin. Before the advent of cheap mild steel the backing metal was iron. While once more widely used, the primary use of tinplate now is the manufacture of tin cans.
Tinplate is made by rolling the steel (or formerly iron) in a rolling mill, removing any scale (rust) by pickling it in acid and then coating it with a thin layer of tin.
Tinplate is light gauge, cold-reduced low-carbon steel sheet or strip, coated on both faces with commercially pure tin. It thus combines in one material the strength and formability of steel and the corrosion resistance, weldability and good appearance with lustre of tin.
