PPGL Steel Coil Durable & Corrosion-Resistant Solution For Roofing And Cladding

What is PPGL?

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.

Key features of PPGL Steel Coil?

1. 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.

2. 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.

3. 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.

4. Aesthetic Flexibility

   • Available in multiple colors, textures (matte/gloss), and finishes to match modern architectural designs.
