Tinplate Coil
Double reduced cold-rolled tinplate coil is given a partial cold reduction to reach an intermediate gauge, then annealed and given another cold reduction to the final gauge prior to coating with tin. The resulting product is stiffer, harder, and stronger than single reduced cold-rolled tinplate coil.

Tinplate coil is a steel product with a stampable thin steel coil as the base, tin plating on the surface, and multiple protective films. It is characterized by corrosion resistance, non-toxic, odorless, glossy surface, light weight, high strength. In the meanwhile, it is easy to weld and process, aside from a strong adaptability to ambient temperature. Double cold-reduced tinplate coil is usually supplied with a stone surface finish and a flow-brightened tin coating. When ordering double cold-reduced tinplate coil, the purpose of manufacture for which the material is intended should be stated. Double reduced cold-rolled tinplate coil is relatively less ductile than single reduced cold-rolled tinplate coil and has very distinct directional properties, so for some uses, for example for built-up can bodies, the direction of rolling should be stated.

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.;
