High Strength PPGI Steel Sheet Anti Corrosion Customized Pre Painted Galvanised Iron Sheet
High-Strength PPGI Steel Sheet - Custom Sizes Anti-Corrosion Coating
High-Strength PPGI (Pre-Painted Galvanized Iron) Steel Sheets are engineered for demanding industrial and architectural applications, combining yield strengths up to 700 MPa with a dual-layer anti-corrosion coating (hot-dip galvanized base + PVDF/polyester topcoat). Available in custom sizes (0.3–3.0mm thickness, 600–2,000mm width), these sheets are ASTM A653, EN 10169, and JIS G3312 certified, ideal for extreme environments like coastal zones, chemical plants, and high-UV regions.
Key Benefits:
- Ultimate Durability: 2,000+ hours salt spray resistance (ISO 9227) and 25+ years lifespan.
- High-Strength Design: Tensile strength of 550–700 MPa for structural applications like bridges and warehouses.
- Eco-Friendly: REACH/RoHS-compliant coatings, 80% recycled steel, and ISO 14001-certified production.
- Aesthetic Versatility: 300+ RAL colors, anti-scratch matte finishes, and custom embossed patterns.
- Cost Efficiency: 30% lighter than traditional materials, reducing transport and installation costs.
- Fast Customization: Laser-cut profiles, pre-punched holes, and fire-retardant options (Class A1).
