Tinplate is a thin steel sheet coated by tin. It has an extremely beautiful metallic luster as well as excellent properties in corrosion resistance, solderability, and weldability.
Tinplate is used for making all types of containers such as food cans, beverage cans, 18-liter cans, and artistic cans. Its applications are not limited to containers; recently, tinplate has also been used for making electrical machinery parts and many other products.
Tin Free Steel (TFS) is produced by applying electrolytic chromic acid treatment over steel sheets. This steel product was developed to meet economic requirements, and excels tinplate in paintability, paint adhesion, and economy. It is widely used for making beverage cans and 18-liter cans. It is also used as a protective material for optical fiber cables.
ETP may be of Single Reduced (SR) or Double Reduced (DR) type and available, both in sheet and / or coil form.
Single Reduced Electrolytic Tinplate (SR ETP)
SR ETP is produced by cold rolling of Hot Rolled Steel Coils followed by annealing and temper rolling the annealed coil, before being coated with tin through an electrolytic process.
We produces SR ETP in a wide range of thickness, temper grades and coatings (including differentially coated ETP) to cater to various end uses:
- Edible oils
- Paints
- Aerosol
- Battery Components
- Processed foods
Double Reduced Tinplate (DR ETP)
DR ETP is normally thinner but stronger than conventional SR ETP. DR ETP is produced by electrolytic coating of tin on a steel, which after an initial cold reduction and annealing is subjected to a second cold reduction with lubrication, which imparts additional strength to Double Reduced material. TCIL produces DR ETP from 0.14 to 0.21 mm in DR08 (DR 550) grade.
