Product Introduction
Electrolytic chromium coated steel also called Tin Free Steel(TFS) is an electrolytic chrome plated steel consisting of a thin layer of chromium and a layer of chromium oxide deposited on the steel base.It has a beautiful, metallic luster as well as excellent properties in corrosion resistance and paintability.

Surface Finishes
| Code | Surface Finish | Characteristics |
| B | Bright surface | Glazed surface obtained by a thin layer of chromium and chromium oxide deposited on the smooth steel base with extremely fine stone figures by processing. |
| R | Stone surface | Glazed surface obtained after a thin layer of chromium and chromium oxide deposited on the smooth steel base featuring certain oriented stone figures. |
| R2 | Stone rough surface | Glazed surface obtained after a thin layer of chromium and chromium oxide deposited on the smooth steel base featuring certain oriented stone figures, roughness higher than “R”. |
| M | Matte surface | Matt surface. |
Main Advantages
1.Excellent resistance to Sulphur Blackening: The metallic chromium in tin free steel has excellent sulphide resistance property when canning protein-rich foodstuff such as fish.TFS compensates for the expensive sulphur resistant lacquer.
2.Excellent heat resistance: High-temperature baking causes neither discoloration nor deterioration in material properties.
3.Excellent filiform rust resistance: TFS has a excellent under film corrosion resistance.
4.Excellent paint adhesion: TFS has excellent paint adhesion properties that far surpass those of ETP, allowing its use for making DRD cans and adhesive bonde cans.
5.Excellent alkali resistance: The coating in TFS is not amphoteric. Alkaline products such as detergents and dispersion colours can be packed in TFS with advantage.
