PRANCE metalwork is a leading manufacturer of metal ceiling and facade systems.
What facade materials perform best in humid or coastal architectural conditions
Humid and coastal conditions accelerate corrosion and coating degradation, so façade materials must be chosen for corrosion resistance, washability, and long-term finish retention. Anodized aluminum, high-quality PVDF-coated aluminum, and stainless steel with appropriate grades (e.g., 316 in severe marine environments) are common choices. These metals resist chloride attack better than painted low-grade steels and maintain visual quality with lower maintenance.
Beyond material selection, detailing is critical: provide drainage, avoid horizontal sills that trap salt and moisture, and specify sacrificial or replaceable components where exposure is highest. Use sealed joints and minimize crevices where corrosive deposits can accumulate. For finishes, choose systems with proven coastal performance and follow manufacturer-recommended maintenance cycles involving salt washdown schedules.
Ventilated metal rainscreens are advantageous because they isolate the insulation from direct exposure and allow drying.
