| High Light | Corrosion-Resistant PPGL Steel Coil ，Roofing PPGL Steel Coil ，Durable PPGL Steel Coil | ||
Prepainted Galvalume (PPGL) is a high-performance steel coil featuring a Galvalume base (55% aluminum, 43.4% zinc, and 1.6% silicon) coated with premium paint or polymer layers. This pre-treatment enhances durability, aesthetics, and weather resistance, making PPGL ideal for roofing, architectural cladding, and industrial applications.
Superior Corrosion Resistance
The aluminum-zinc alloy coating provides robust protection against rust, even in coastal or high-humidity environments.
The prepainted layer (PE/SMP/PVDF) adds an extra barrier against UV rays, chemicals, and abrasion.
Long-Term Durability
Withstands extreme weather conditions (heat, rain, snow) and maintains structural integrity for over 20-25 years.
UV-resistant coatings prevent fading, ensuring lasting color vibrancy.
High Strength & Lightweight
Offers excellent load-bearing capacity (35–50 kg/sqm for 0.5mm panels) while remaining easy to install.
Ideal for large-span roofing and façades without compromising structural safety.
Aesthetic Flexibility
Available in multiple colors, textures (matte/gloss), and finishes to match modern architectural designs.
