Group 1 Tinplate and Tin Free Steel
1. Product types
1.1 Tinplate is made of Tin Mil Blackplate coated
with tin by electrolytic tinplating process.
1.2 Tin Free Steel is made of Tin Mill Blackplate
coated with chromium / chromium oxide by electrolytic chromium plating process.
Note : Tin Mill Blackplate (TMBP) is cold reduced low carbon mild steel.

1. Coating weight corresponds to JIS G 3303 and JIS G 3315 for Tinplate and Tin Free Steel respectively.
2. Value in front of slash (/) is for upper surface and value behind slash is for lower surface of sheet.
3. For differentially coated plate, differential mark will normally be presented on heavily coated side, or other side according to customer’s requirement.
4. Heavier or lower coating weight is available upon request.3. Surface Finished
