Are Ceiling Hung Aluminum Panels Corrosion Resistant?

Aluminum by nature forms a protective oxide layer that resists rust, but in aggressive environments—such as coastal zones or chemical plants—additional treatments ensure long-term performance. Our ceiling hung aluminum panels receive a two-step process: first, a chromate conversion coating to seal surface pores; second, a fluoropolymer powder coat or anodized finish that bonds directly to the substrate. Fluoropolymer coatings provide superior UV and salt-spray resistance per ASTM B117 standards, lasting over 2,000 hours without blistering. Anodized panels—available in Class I or II thickness—deliver corrosion resistance while exposing natural metallic luster. All edges are sealed with epoxy resin to prevent moisture ingress at cut-lines. Stainless-steel fasteners and clips complete the system, eliminating dissimilar-metal corrosion. Periodic cleaning with mild detergent maintains aesthetic quality, and our team provides cleaning protocols tailored to facility conditions. Whether used indoors or under overhangs on façades, these ceiling hung aluminum panels maintain structural integrity and finish intelligence for decades, reflecting our expertise in aluminum ceilings and facades.
