PRODUCT DESCRIPTION
Electrolytic Tin Free Steel (TFS), also known as Electrolytic Chromium Coated Steel (ECCS), is a type of steel that is coated with a thin layer of chromium and chromium oxide through an electrolytic process. This coating provides the steel with excellent corrosion resistance, a superior surface finish, and good paint adhesion properties, without using tin. The steel used is typically low-carbon cold-rolled steel, ensuring a smooth and uniform surface.
