Comprehensive Guide to PPGI and PPGL in China

PPGI (Pre-Painted Galvanized Iron) and PPGL (Pre-Painted Galvalume) are essential materials in the construction and manufacturing industries, particularly in China. These products are known for their durability, aesthetic appeal, and versatility. This guide will delve into the technical features, differences between types, and applications of PPGI and PPGL, highlighting key manufacturers and suppliers in the industry.

Understanding PPGI and PPGL

PPGI is a type of steel that has been coated with a layer of zinc to prevent corrosion. It is then painted to enhance its appearance and provide additional protection. PPGL, on the other hand, uses a substrate of aluminum-zinc alloy, offering superior corrosion resistance and heat reflectivity. Both materials are widely used in roofing, wall cladding, and various industrial applications.
