How do metal wall coatings resist corrosion from coastal salt in Oman?
Coastal cities in Oman such as Muscat and Salalah face high levels of airborne salt and humidity, which accelerate corrosion on traditional building materials. Aluminum metal wall systems with marine-grade coatings provide a durable solution in such environments.
Our aluminum panels are treated with PVDF or fluoropolymer finishes rated for salt spray resistance up to 3,000+ hours (ASTM B117). These coatings form a non-porous surface barrier, protecting the base metal from oxidation and salt crystallization.
Additionally, aluminum’s natural oxide layer already offers a degree of corrosion resistance. When enhanced with anodizing or marine-grade paint systems, the panels can last decades without structural degradation or discoloration.
For Oman’s coastal projects, it is also important to use stainless steel fixings, water-resistant subframes, and drainage-designed assemblies to avoid water accumulation and galvanic corrosion. Clients in Sur and Sohar have reported excellent performance from aluminum cladding systems under these conditions.
In conclusion, with proper coatings and engineered substructures, aluminum metal wall systems deliver long-lasting performance in coastal environments like Oman.
