Product Description

PPGL color coated galvanized steel roof sheets are manufactured using Al-Zn coated steel substrate (55% Aluminum, 43.5% Zinc, 1.5% Silicon), also known as Galvalume steel, which provides superior corrosion protection compared to traditional GI. The surface is further enhanced with a pre-painted organic coating, available in various colors and finishes.

These roof sheets are roll-formed into corrugated, trapezoidal, or tile profiles, delivering both aesthetic appeal and structural strength. The PPGL system is known for its heat reflectivity, scratch resistance, and long-term weather durability, making it a high-end choice for modern roofing projects.
