Tin-plated steel plate, commonly known as tinplate is a steel product with a stampable thin steel plate as the base, tin plating on the surface, and multiple protective films. It has the characteristics of corrosion resistance, non-toxic, odorless, glossy surface, light weight, high strength, easy to print, easy to weld and process, and has strong adaptability to ambient temperature. Single cold-reduced tinplate can be supplied with either a bright, silver, stone or matt finish, and the finish required shall be specified at the time of ordering. Single reduced cold-rolled tinplate is generally specified in nominal thicknesses that are multiples of 0,005 mm, from 0,150 mm up to and including 0,600 mm. It is widely used in food, beverage, grease, chemical, paint, paint, aerosol cans, bottle caps and many other daily necessities packaging, such as a variety of beverage cans, food cans, beer bottle caps and so on.

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.;
