Types of lubricant treatments available for GA steels include further iron plating on top of it's surface1), a reaction type prephosphate treatment in which a preparatory fine phosphate coating is formed on the plating and a non-water rinse type prephosphate treatment in which phosphate treatment is conducted without the water rinsing stage.

The development of a new corrosion-resistant coating composite for automotive sheet metal is described. The three-layer coating combines the galvanic properties of a thin electroplating with the passivating and barrier protection of an inorganic intermediate layer and an organic outer layer. ...The plating layer provides galvanic action as the last line of defense, being called into play only after the initial two coatings are exhausted. The zinc coating then corrodes galvanically to protect the underlying steel. ...Corrosion tests indicate that this combined coating is more effective than the individual coatings alone. This composite thus allows a relatively thin zinc electroplating to be used, and welding and forming problems are minimized.
