- Black Plate is a light gauge, low carbon, cold reduced steel intended for use in the non-tinned state, for prepainting, or for the production of other Tin Mill Products dependent on end use corrosion protection requirements.
- Single Reduced product is cold rolled to the finished gauge, then continuously annealed and coated with a thin layer of tin.
- Double Reduced product 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, in some cases, allowing customers to utilize lighter gauge steel in their application.
Tin Free Steel
- Electrolytic Chromium Coated plate or Tin Free Steel is a Tin Mill Black Plate product which has been coated with metallic chrome overlaid with film of chrome oxide by electrolytic deposition.
