Characteristics of prepainted galvanized steel :
The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color coated sheet. In addition to the protective effect of hot-dip galvanized sheet, the organic coating on the surface also plays a role of insulation protection and rust prevention, and its service life is longer than that of hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180g / m2 (double-sided), and the maximum galvanized amount of the hot-dip galvanized substrate for external use is 275g / m2.
