General Description
Surface treatment plates, such as galvannealed and aluminum plated steel plates, are used for enhancement of corrosion-resistance in steel materials, currently meeting the increasing demands in automobile and construction industry. In particular, the galvannealed steel sheet (GA steel sheet) with more or less coating layer of 10um, excellent in economicalness, corrosion resistance and weldability, is characterized by the variance in color, adhesion and powdering, depending on the percentage of iron over the surface of coating layer.
