The process of covering steel, iron, or other metal with a layer of tin by dipping it in the molten metal, by electroplating, or by immersion in solutions that deposit tin by chemical action of their components. Ingredients for the chemical process are cream of tartar and stannous chloride. The metal being plated also takes part in the process. The objective is to utilize the superior corrosion resistance of tin and in some cases to improve appearance.See Terneplate.
