Differential Thickness Tinplate
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.

Among them, differential thickness tinplate refers to tinplate whose one surface carries a heavier coating than the other.
Differential Thickness Tinplate Description
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.

Ordering Notes
The ordering elements for tin plating generally include: standard grade (including steel grade code, annealing method and other information such as MR T-3 CA), size (the default order is thickness * width * length, tin plating amount ((different thickness plating) Tin needs to add A/D as the marking line mark, if not, no marking line will be marked), surface, order quantity, etc.
When ordering tin plating, please confirm with our sales staff the end use, such as canbody, ends, twist off caps, crown cork, EOE, etc., as well as the contents, special contents such as milk powder, high protein food, mushrooms, fruits, etc.; -
