pre-painted galvanized steel coil

Surface structure

Characteristics

Application

Normal spangle (Z)

Under the common conditions, the galvanized zinc makes spangle after condensation.

Common usage

Finishing spangle (G)

Finish the galvanized sheet by finishing machine, and level off the spangles on the galvanized sheet.

Used as base lamina of color coated sheet.
