This product is an extension of hot-dip galvanized steel sheets, a deep-processed steel sheet produced by first surface treating the galvanized steel sheet and then applying paint or bonding an organic film. It is suitable for further deep processing through cold pressing. It primarily consists of three parts: cold-rolled steel base material, galvanized layer, and coating, and is an emerging material that has developed in recent years. It boasts good decorative properties, formability, corrosion resistance, and strong coating adhesion, ensuring a long-lasting fresh appearance.
