Product Description
According to the difference of the tin plating thickness on the front and back of the thin steel plate, tinplate can be divided into two types: equal thickness tinplate and difference thickness tinplate. Among them, differential thickness tinplate refers to tinplate whose one surface carries a heavier coating than the other. Tinplate, also known as tin-plated steel, is a thin steel plate plated with a layer of tin on both sides. The purpose of this coating is to provide corrosion protection and enhance the appearance of the steel. Differential coated tinplate is electrolytic tinplate, one surface of which carries a heavier coating than the other. This material is used principally for the manufacture of containers which require higher corrosion resistance inside than outside. In order to distinguish material having differential coatings, it is customary to mark one surface. Differential coatings may have economic advantages when the corrosive conditions to be encountered by the two surfaces differ in severity.
