The steel can be coated with differing thicknesses of tin, and even different thicknesses on the two faces (differential coatings) may be produced to cater for varying conditions at the internal and external surfaces of a container.

Developed jointly by Tata Steel and other leading European steelmakers, CFPA tinplate is fully compliant with European Union regulations prohibiting the use of hexavalent chromium (chromium VI) in tinplate manufacture. . Performance benefits. Production process is 100% free from hexavalent chromium.
Steels for packaging are thin gauge flat carbon steels, tin or chromium coated on both sides. This particular combination gives the tinplate an interesting set of properties: strength and stiffness, formability, weld-ing ability, lacquer ability and printability, good cosmetic appearance and corrosion resistance.
An underplate of nickel at least 50μ" thick is required for tin coatings of 100μ" or less that will not be exposed to solder temperatures (especially ones that will function as a conductive surface).
