PPGI Coil – Prepainted Galvanized Steel Coil for Roofing & Cladding Applications

|

 Product introduction

PPGI coil (Prepainted Galvanized Iron Coil) is a galvanized steel coil that is pre-coated with color paint on both sides. It is manufactured through a continuous coating process, where the base material is hot-dip galvanized steel (usually DX51D+Z or SGCC grade), followed by primer coating and top finish coating.

This product combines the mechanical strength of steel, the corrosion resistance of zinc, and the decorative appeal of organic coatings. It is lightweight, easy to process, and available in a wide range of colors, making it widely used in modern construction and industrial applications.

• Excellent corrosion and UV resistance

• High color retention and gloss stability

• Superior adhesion and scratch resistance

• Smooth surface, uniform thickness
