SuperGalum Color SuperGalum Color, a brand name of Dongbu Steel Company, is a prepainted SuperGalum(55% Al-Zn Coated steel)steel sheet. The base material of SuperGalum Color is SuperGalum steel sheet, which is produced by the state-of-the-art facility of Asan Bay Works. SuperGalum Color is chromated with high grade coating materials and processed by the “Two-Coat Two-Bake” system for the excellent adhesion and atmospheric corrosion resistance.

Application

SuperGalum® Color Cross-sectional structure

Characteristics ▣ Long-Term Durability ▣ A wide variety of Color SuperGalum steel sheet, the base material of SuperGalum Color, offers corrosion protection 3 to 6 times greater than galvanized steel sheet with the same thickness. A broad range of color for SuperGalum Color can be offered to the customers. ▣ Excellent Paint Adherence ▣ Extra area SuperGalum Color steel coil provides more additional area per ton than the prepainted galvanized steel coil due to the lower density of SuperGalum. The specially developed primers are applied to SuperGalum Color to enhance paint adhesion and formability.
