Low Carbon or Mild Steel is coated with tin on one por both side following the electrolytic operation. ETP can be Single Reduced (SR) or Double Reduced (DR) or Soft Double Reduced (Soft DR ETP) available both Sheet and Coils form.
Tinplate is made by rolling the steel (or formerly iron) in a rolling mill, removing any mill scale by pickling it in acid and then coating it with a thin layer of tin.
Tinplate consists of sheets of steel, coated with a thin layer of tin. Before the advent of cheap milled steel the backing metal was iron. While once more widely used, the primary use of tinplate now is the manufacture of tin cans.
Tin Free Steel (TFS) is produced by applying electrolytic chromic acid treatment over steel sheets so that they are coated by a thin film composed of lower layer metallic chromium and upper layer chromium hydroxide.
Tin Mill Black Plate (TMBP) is a light guage, low carbon, cold reduced steel which does not have any additional metallic coating during production. TMBP is the basic material for the production of electrolytic tinplate. It is generally available in dry, oiled or chemically treated finish and its appearance is dependent on the surface roughness of the steel base. We procure TMBP in all forms, sizes, shapes and qualities.
It is intended for use in the non-tinned state, for pre-painted or for the production of other tin mill products dependent on end use corrosion protection requirements.
