Prime Z275 Hot Dipped Galvanized Steel Coil Z275 GI Sheet Coil

  Galvanized steel sheet Z275—namely galvanized steel sheet, Z275: zinc layer weight code, indicating the weight of zinc on both sides of the steel sheet, expressed in grams per square meter of zinc on the steel sheet (g/m^2), Z275— —The weight of the zinc layer is 275g/m^2.Normal spangle (Z) Spangle obtained from the condensation of the zinc layer under normal conditions after galvanizing. Finishing spangle (GZ) The galvanized sheet is smoothed by a finishing machine, and the surface of the galvanized sheet is flattened. It is mainly used as the base plate of the color-coated sheet.
