[0002] Galvanized steel sheet is a welded steel sheet with hot-dip or electroplated zinc layer on the surface. It is widely used in construction, home appliances, vehicles and ships, container manufacturing, electromechanical industry, etc. Galvanized steel sheet is divided into ordinary electrolytic sheet and fingerprint-resistant electrolytic sheet. Fingerprint-resistant sheet is a fingerprint-resistant sheet added on the basis of ordinary electrolytic sheet. It is sweat-resistant and is generally used on parts without any treatment. The grade is SECC-N. Ordinary electrolytic sheet is divided into phosphated sheet and passivated sheet. Phosphating is more commonly used. The grade is SECC-P, commonly known as p material.
