​PPGI Corrugated Roofing Sheets | Zinc-Aluminum Coated, JIS G3322, 1000mm Width

PPGI Corrugated Roofing Sheets are engineered with a ​zinc-aluminum alloy coating (55% Al, 43.4% Zn, 1.6% Si) for unmatched corrosion resistance and longevity in harsh environments. Compliant with ​JIS G3322 standards and available in a ​1000mm standard width, these sheets are ideal for industrial, agricultural, and coastal applications. The corrugated design enhances structural strength while reducing installation time and material waste.

Key Benefits:

• ​Superior Corrosion Resistance: 3,000+ hours salt spray resistance (JIS Z2371), outperforming traditional galvanized coatings.
• ​Heat Reflectivity: High aluminum content reflects 80% of solar radiation, reducing cooling costs.
• ​JIS G3322 Compliance: Certified for SGH340, SGH400, and SGH440 grades, trusted in Japanese and Asian markets.
• ​Wide Format Efficiency: 1000mm width minimizes seams for large-scale roofing projects.
• ​Eco-Friendly: Halogen-free coatings, 85% recycled steel content, and REACH-compliant production.
• ​Cost Savings: 20% lighter than galvanized steel, lowering transportation and handling costs.
