(1) Tin plating amount

It is expressed as the weight of tin plated on a tin plate on a certain area. In general, China stipulates the amount of tin plating in grams per square metre per square meter (grams per meter2), which is expressed internationally in terms of pounds/basic box×100. 11.2 g/m2 is equivalent to 1 pound/base box, and the international tinplate quantity is #100; the common 2.8 g/m2, 5.6 g/m2 is #25, #50.

The difference between thick and thick tin plating is that the amount of tin plating on the upper and lower surfaces is different. Generally, a thick thick mark is printed on one side.


(2) Tin plated surface

According to the final treatment after electroplating tin, generally can be divided into shiny and matt surface. The matt surface is made without tin reflow after electroplating. It can also be classified according to the surface smoothness of the rolls during smoothing.


(3) Conditioning

The degree of conditioning is based on the use, which is mainly reflected in the mechanical properties of the strength and processing performance.
