Color Coated PPGI Steel Corrugated Sheets Fire Resistance, 0.4-0.7mm Thickness
Fire-Resistant Color Coated PPGI Steel Corrugated Sheets are engineered for safety-critical applications, combining a fire-retardant coating with vibrant color durability. With a thickness range of 0.4–0.7mm and compliance with ASTM E84 Class A standards, these sheets are ideal for commercial buildings, industrial facilities, and public spaces requiring enhanced fire safety. The zinc-aluminum-magnesium alloy base (ZAM coating) and PVDF/polyester topcoat ensure 1,500+ hours of salt spray resistance and 20+ years of UV stability.
Key Benefits:
- Class A Fire Rating: ASTM E84-certified, limiting flame spread and smoke generation.
- Ultra-Durable Coating: 25–35µm PVDF/polyester layer with anti-scratch and anti-fade properties.
- Lightweight & Strong: Corrugated design enhances rigidity while reducing weight (3–6kg/m²).
- Global Compliance: ASTM E84, EN 13501-1, JIS G3322, and ISO 1461 certified.
- Eco-Friendly: Halogen-free coatings, 80% recycled steel, and REACH/RoHS compliant.
- Aesthetic Versatility: 150+ RAL colors, metallic finishes, or custom textures.
