Roofing PPGI Galvalume Corrugated Steel ISO 9001 Certified, 24-28 Gauge
PPGI Galvalume Corrugated Steel combines the superior corrosion resistance of 55% aluminum-zinc alloy (Galvalume) with a pre-painted polyester/PVDF coating, offering unmatched durability for roofing and cladding in harsh environments. Certified to ISO 9001, ASTM A792, and EN 10346, these sheets are available in 24–28 gauge thickness (0.55–0.35mm) and standard widths up to 1,200mm, ideal for agricultural, industrial, and commercial projects requiring lightweight yet robust solutions.
Key Benefits:
- Galvalume Advantage: 3x longer lifespan vs. traditional galvanized steel, with 1,500+ hours salt spray resistance (ISO 9227).
- Lightweight Efficiency: 24–28 gauge thickness reduces material costs while maintaining structural integrity.
- Aesthetic Versatility: 100+ RAL colors, anti-scratch matte finishes, or woodgrain textures.
- Global Compliance: ASTM A792, EN 10346, JIS G3321, and ISO 9001 quality assurance.
- Eco-Friendly: 80% recycled steel content, REACH/RoHS-compliant coatings, and low-VOC production.
- Fast Installation: Pre-painted surfaces and corrugated profiles reduce labor time by 25%.
