PPGL Steel Sheet is a color-coated steel product made from galvalume (GL) steel substrate with an additional layer of paint. It combines the mechanical strength of steel with the superior corrosion resistance of a zinc–aluminum alloy coating.

The galvalume coating typically consists of 55% aluminum, 43.4% zinc, and 1.6% silicon. This composition provides excellent long-term corrosion resistance, especially in harsh outdoor and industrial environments. In addition, PPGL sheets offer high thermal reflectivity, which helps improve heat resistance and reduce heat absorption.

PPGL steel sheets are available in a variety of colors and surface finishes, making them suitable for both functional and decorative purposes. They are widely used in roofing systems, wall cladding, oil storage tanks, refrigeration equipment, and various architectural and industrial applications where durability, corrosion resistance, and appearance are all important.
