Are Paneles Metálicos Suitable for Coastal Building Facades?

Metal panel systems can perform exceptionally well in coastal facades when designed to resist salt-laden air and high humidity. Selecting marine-grade aluminum alloys from the 5000 series provides inherent corrosion resistance against chloride attack. Applying anodized or high-build PVDF finishes seals the panel surface, creating a barrier that inhibits salt crystal penetration and paint degradation. Edge treatments—such as sealed hems or liquid-seal edge coatings—prevent cut-edge corrosion where raw aluminum is exposed. Rainscreen assemblies with back-ventilation promote airflow behind panels, flushing out retained moisture and salt deposits. Stainless steel fasteners and clips specified to A316 standards ensure supporting hardware doesn’t corrode and weaken. Routine maintenance schedules that include gentle pressure washing remove salt build-up before it compromises coatings. When these best practices are implemented, aluminum panel systems deliver durable, low-maintenance facades with the aesthetic versatility coastal architects demand.
