FAQ
The reasons for the color difference of the PPGI&PPGL sheet
The color difference of the paint itself; The drying process; Paint coating thickness; Glossy of paint;
Why are the same specifications, the price of Chinese manufacturers different?
Different regions. Taking Ukrainian customers as an example, the specifications for purchasing color coated steel coils are 0.3*1250 mm, and the paint is 18μm(top paint)/5μm(back paint). Our price is 730 US dollars per ton. The price of a manufacturer in southern China is 715 US dollars per ton. Because of the time difference between the price adjustment of raw materials in southern China and northern China. Cost accounting differences. PPGI products have different prices due to raw materials, paint quality, stock availability and other reasons. Other manufacturers offer 13μm(top paint)/5μm(back paint) color coated coil prices to customers as 18μm(top paint)/5μm(back paint) PPGI&PPGL steel coil.
