Marble pre-painted galvanized steel coil

PPGI is short for Prepainted galvanized steel PPGI is a product made by chemical treatment of coated steel sheets and then coating and baking.It has not only mechanical strength and easy forming property of steel plate, but also good decorative and corrosion resistance of organic materials. The coatings have strong adhesion and can keep novel color for a long time.

The total thickness of the pre-panted galvanized steel coil is composed of the base steel – coating -primer – top paint – protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm. The thinner the base steel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher.

Usually the paint coating material is polyester (PE) and the color of the back paint is white grey. The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print, camouflage, brick.
