In addition to regular Hot Rolled Coil & Sheets, TSPDL also supplies Hot Rolled Pickled and Oiled Steel. The Hot Rolled Pickled and Oiled Steel is the steel obtained when the hot rolled steel is pickled in acid to remove the mill scale and then oiled to keep it from rusting.
Hot rolled steel has scales on its surface which are remnants of cooling from extreme temperatures. However, there are some applications of hot rolled steel that require a uniform and clean surface.
It is the pickling process that removes these scales from hot rolled steel surface using water and other inorganic solutions. The process yields Hot Rolled Pickled and Oiled Steel which is free from scales and ideal for applications that require a clean, uniform surface and good flatness.
The primary advantage or purpose of the pickling and oiling conditioning is to reinforce the steel's protective properties, in particular, against rust.
