Weatherproof Aluminum Steel Coil 0.7mm-3.5mm Thickness Solar Panel Framing Material
Weatherproof Aluminum Steel Coil 0.7-3.5mm Thickness Solar Panel Framing Material
Weatherproof Aluminum Steel Coil is engineered for extreme outdoor durability, making it the ideal material for solar panel framing, agricultural structures, and coastal construction. Certified to ASTM A755 and EN 10346 standards, this coil combines a 55% aluminum-zinc alloy coating with a proprietary weather-resistant finish, ensuring decades of performance in harsh UV, rain, and salt environments. Available in 0.7–3.5mm thicknesses and widths up to 2,000mm, it offers unmatched corrosion resistance, lightweight strength, and cost-efficiency for renewable energy and outdoor projects.
Key Selling Points:
- Ultimate Weather Resistance: Withstands 2,000+ hours of salt spray (ASTM B117) and UV exposure (ASTM G154).
- Solar-Ready Design: Compatible with solar panel mounting systems (IEC 61215 compliant).
- Lightweight & Strong: Tensile strength up to 550 MPa, 30% lighter than galvanized steel.
- Eco-Certified: Recyclable and compliant with LEED, BREEAM, and RoHS standards.
- Easy Installation: Pre-drilled holes or custom-cut profiles for rapid solar farm assembly.
