In order to improve the A283 grade C mild steel coil corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating.

Oxygen is a harmful element in A283 grade C mild steel coil steel. With the increase of oxygen content, the strength of A283 grade C mild steel coil steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of A283 grade C mild steel coil steel.
