PPGI (Prepainted Galvanized Iron) steel coil is a color-coated steel product widely used for roofing sheets, wall cladding, and prefabricated building systems.
PPGI (Prepainted Galvanized Iron) steel coil is a premium coated steel product manufactured by applying paint coatings over galvanized steel substrate. The process combines the corrosion resistance of zinc with the aesthetic color finish of paint, making it ideal for visible building applications.
As a PPGI coil manufacturer in China, Shandong Ruizhite produces PPGI coils conforming to GB/T 12754 standards, available in a wide range of RAL colors and coating thicknesses.

Typical MOQ is one 20-foot container — about 25-28 tons. Within one container, we can usually split into 2-3 colors if each color meets a minimum weight. For popular colors (like RAL 3009 red or RAL 9002 grey-white), the minimum per shade is lower. For unusual custom RAL colors, we may need a full container per shade.
PE (Polyester) works fine for most standard roofing and wall cladding — it's affordable and holds up for 5-10 years. PVDF (Fluorocarbon) costs 30-50% more but lasts 15-20+ years without fading. Pick PE if you're building industrial warehouses on a budget; pick PVDF if your building's exterior is visible to clients and you want it to look good for decades. We carry both.
Production takes 15-25 days after deposit confirmation. Add sea freight transit time — typically 10-15 days to Southeast Asia, 20-25 days to the Middle East, and 30-40 days to Africa or South America. We'll give you a schedule you can actually plan around.
