SuperGalum® Color

SuperGalum Color, a brand name of Dongbu Steel Company, is a prep

ainted SuperGalum(55% Al-Zn Coated steel)steel sheet. The base mate

rial of SuperGalum Color is SuperGalum steel sheet, which is produce

d 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 atmosph

eric corrosion resistance.

SuperGalum steel sheet, the base material

of SuperGalum Color, offers corrosion prot

ection 3 to 6 times greater than galvanized

steel sheet with the same thickness.

SuperGalum Color steel coil provides mor

e additional area per ton than the prepaint

ed galvanized steel coil due to the lower d

ensity of SuperGalum.

A broad range of color for SuperGalum Col

or can be offered to the customers.

The specially developed primers are appli

ed to SuperGalum Color to enhance paint

adhesion and formability.

▣ Long-Term Durability ▣ A wide variety of Color

A: For sheet thickness of 0.028 in. and thinner, no tension test is required if the hardness result is Rockwell B 85 or higher

B: As there is discontinuous yield curve, the yield strength should be taken as the stress at 0.5% elongation under load 0.2% offset

C: Where an ellipses(.-) appears in the table, there is no requirement
