Tinning, like galvanizing, is a practical method of coating iron and steel to render it non-corrodable. Tinning gives a smoother, brighter and better-looking surface, and it forms a more durable coating, than does galvanizing. Very common among tinned products are tinned wire, roofing tin, tin-lined cooking vessels, and cans in which preserved fruits and vegetables are held.
