Most of China’s prepainted galvanized(PPGI) coil manufacturers are located in Boxing County, Shandong Province, and Guan County, Liaocheng.
When you are inquiring about prepainted galvanized steel coil, it is best to list detailed specifications, such as thickness, width, coil weight, coil diameter, packaging method, color, paint type, steel grade (DX51D, etc.).
Only in this way can a more accurate price be obtained.
At present, many PPGI coil manufacturers reduce material in the middle of the steel coil, such as reducing the thickness of the paint coating.
This is why the price of the same specifications differs by tens of dollars per ton from different factories.
When import PPGI coil, galvanized coils can consider choosing COSASTEEL, we can use paint thickness inspection tools to let you check.
