Hot-rolled pickled dry steel sheet and coil is descaled of oxides and rinsed, but the materials surface is not oiled after pickling. Hot rolled steel products will scale when in contact with oxygen and water vapor after the forming process. An acid bath removes scale and surface oxides that usually form on the surface of hot rolled steel as it cools. After pickling and rinsing, hot rolled pickled dry steel is stored in our climate-controlled warehouse.

A roll or sheet of hot-rolled steel is dipped or passed through a pickling bath. A solution of very strong acid removes the scale and dirt from the sheet or plate, leaving the raw steel exposed. It is then passed or dipped in an oil bath to protect the raw steel from oxidation, which would begin immediately without protection, especially in humid environments.
