Corrosion or the more common term for it is rust and that is a big problem in the steel industry. Rust is a general term for describing iron oxides. The term is applied to red oxide, which is formed by the reaction of iron and oxygen in the presence of water or air moisture. There are also other forms of rust, such as the result of the reaction of iron and chloride in an environment deprived of oxygen, this then generates green rust.

Given sufficient time, oxygen, and water, any iron mass will eventually convert entirely to rust and disintegrate. Surface rust provides no protection to the underlying iron. If salt is present as, for example, in salt water, it tends to rust a lot quicker, as a result of the electro-chemical reactions. Corrosion has shown to be dictated by the availability of water and oxygen.

Tubecon has the capability of rolling round, square and rectangular steel sections, lip channels and tubes from corrosion resistant material such as pre-galvanized steel (Z275 and Z450) or 3CR12 stainless steel. Lip channels are most popular in Z275 while industries such as Automotive makes use of 3CR12 stainless steel to ensure a longer life span of the steel tubes and customized open profiles.
