Tinplate is a light gauge steel that is electrolytically coated with pure tin for enhanced corrosion protection. It is available in either a highly reflective bright surface, or as a non-reflective matte finish. Tinplate is highly formable and weldable, making it suitable for a wide range of canmaking technologies. Because of its corrosion resistance, a wide variety of food products can be packed in tinplate cans. Tinplate is ideally suited as a base metal for lithography and organic coatings for items such as decorative tins, aerosol cans, and paint cans.
Tin Free Steel
Commonly called TFS, tin free steel is actually a light gauge, electolytically coated chromium sheet. It is a more economic alternative to tinplate, primarily used for can ends. TFS is an excellent base for organic coatings and lithography. In addition to can ends, TFS is also used for lockseamed can bodies, as well as numerous non-container items.
Black Plate is a light gauge cold rolled sheet steel and is the base metal for all tinplate and TFS. Some manufacturers use black plate in its uncoated state for a wide array of products, such as curtain rods, building supply products, and toys, among other applications.
