This product is an extension of galvanized steel sheet, a deep-processed steel sheet that undergoes surface treatment first, followed by coating with paint or bonding an organic film to produce. It is suitable for further deep processing through cold forming. It primarily consists of three parts: cold-rolled steel base material, galvanized layer, and coating, and is a new material that has emerged in recent years. It boasts good decorative properties, formability, corrosion resistance, and strong coating adhesion, maintaining a fresh appearance over a long period.
