Pre-Painted Galvanized Steel Coils Anti-Corrosion Coating 0.5-3mm Building Panels
Pre-Painted Galvanized Steel Coils combine cutting-edge corrosion resistance with architectural elegance, designed for modern construction and industrial projects. Featuring a hot-dip galvanized base (Z275 coating) and a high-performance PVDF or polyester finish, these coils (0.5–3mm thick) withstand harsh climates, UV radiation, and chemical exposure while offering vibrant, fade-resistant colors. Ideal for façades, roofing, and cladding, they meet EN 10169, ASTM A755, and AAMA 2603 standards for global compliance.
Key Benefits:
- Superior Weather Resistance: PVDF coating guarantees 30+ years of color retention and 1,500+ hours of salt spray resistance.
- Lightweight & Strong: 30% lighter than traditional materials, with tensile strength up to 550 MPa for structural flexibility.
- Eco-Friendly: REACH, RoHS, and LEED-compliant production with 80% recycled steel content.
- Custom Aesthetics: 200+ RAL colors, woodgrain patterns, and gloss/matte finishes available.
- Fire Safety: Class A fire rating (ASTM E84) for commercial and residential applications.
- Cost Efficiency: 20% lower installation costs due to pre-finished surfaces and minimal maintenance.
