Early hot rolling strip mills did not produce strip suitable for tinning, but in 1929 cold rolling began to be used to reduce the gauge further, which made tinning achievable. The plate was then tinned using the process outlined above. [citation needed]Tinning processes. There are two processes for the tinning of the black plates: hotdipping and electroplating.
