Galvalume coating surface is made from 55% aluminum, 43.5% zinc and a little amount of other elements,while galvanized is 100% zinc.
1.Surface Difference
The surface of galvalume sheet is more beautiful than galvanized sheet,
while the galvalume sheet is more expensive than galvanized sheet.
And now the customer like the small spangle than regular spangle
2.Corroision Difference
In a rainy and humid city, once corrosion occurs at some point on galvalume sheet, it will spread increasingly on whole board if you do not take measures timely to slowly rust;
while galvanized rust not spread if it occurs at a point.
Even a galvalume with greatest quality cannot overcome this shortcoming. Therefore, when we propose customers of the galvanized products, we will explain to customers the difference between them,
if they require galvalume products, then we can only try to use corrosion paint immediately once it is cut.
