Tin is an important raw material in the packaging industry for the manufacture of a wide range of products, including food cans, aerosol cans, ends and closures. Tin products from U. S. Steel are available in four categories:

• Electrolytic tinplate—very thin material with a thin coating of tin on steel
• Electrolytic chromium coated steel—very thin material with a thin coating of chrome on steel, also known as tin-free steel (TFS)
• Blackplate (uncoated)—very thin cold-rolled substrate produced in thicknesses <0.0142”
• Drawn & Ironed (D&I)—specialty type of tinplate designed to be deep drawn into a two-piece can

In addition to packaging products, tin is a highly effective material choice used in automotive products such as oil filters, gaskets, battery tops and vehicle trim. Tin also is important contributor to product performance in construction materials like ducts, shelving, utility sheds and cable sheathing.
