Hot rolled products are available in five product groups:

• Formable
• Extra Formable
• Structural
• Carbon Hardness

The temperature at which hot-rolling is completed results in an oxidized strip surface. This oxide film is termed hot-mill scale. Pickling removes the hot-mill scale. Pickled strip is generally supplied oiled to preserve this surface finish. Skin passing is a light cold rolling operation which suppresses the appearance of stretcher strain and minimizes coil break during uncoiling and subsequent processing. The surface texture and flatness are improved by skin passing.
