ASTM A755 PPGI Corrugated Steel Sheet 0.2mm-1.5mm Galvanized Color Roofing Sheets
PPGI Corrugated Steel Sheet | Galvanized Coating, 0.2-1.5mm Thick, ASTM A755
PPGI Corrugated Steel Sheets are engineered for superior weather resistance and structural durability, combining a hot-dip galvanized base (Z60–Z275) with a high-performance polyester/PVDF coating. Compliant with ASTM A755 standards, these sheets are ideal for roofing, cladding, and agricultural buildings, offering a lifespan of 20–30 years even in coastal or high-UV environments. Available in 0.2–1.5mm thicknesses and customizable corrugation profiles, they deliver unmatched strength, aesthetics, and cost efficiency.
Key Benefits:
- Dual-Layer Protection: Galvanized base + organic coating for 1,500+ hours salt spray resistance (ISO 9227).
- Lightweight & Durable: Corrugated design enhances load-bearing capacity while reducing material weight by 25%.
- Aesthetic Versatility: 150+ RAL colors, woodgrain textures, or anti-scratch matte finishes.
- Global Compliance: ASTM A755, EN 10169, JIS G3312, and ISO 1461 certified.
- Easy Installation: Pre-fabricated corrugations reduce on-site labor costs by 30%.
- Eco-Friendly: 75% recycled steel content, RoHS-compliant, and low-VOC coatings.
