It’s mainly used in household appliance and auto industry. There is little surface defect (zinc thickness fluctuation, silver, etc.) in the galvanized sheet, its surface quality can reach to S3 or higher. Its adhesion of zinc is good, formability is better than SGCC, meeting the requirements of household appliance and auto steel that need bending and drawing.
