Marine & Coastal Coating

Marine & Coastal Powder Coating

Marine powder coating is a specialized class of coatings designed to withstand the harshest environments—where salt spray, humidity, UV radiation, and water exposure cause rapid metal corrosion. At Rainbow Powder Coating, we provide eco-friendly protective finishes that extend the life of marine equipment, watercraft parts, and coastal architectural elements.

Why Marine Powder Coating?

In marine and coastal environments, metals are exposed daily to air, salt, water, and sunlight—a highly corrosive combination that leads to premature deterioration. Powder coating forms a tough, seamless barrier that protects aluminum, steel, brass, and copper from corrosion while offering superior aesthetics and long-term durability.
