Industrial metal paints play an important role in finishing metal parts, products, and components. Painting custom metal fabrication and precision sheet metal fabricated parts and assemblies is done for many reasons, such as providing added colour or identifying a brand or product. However, painting also works to supply a protective finish to metal surfaces.
Protective metal coating processes are applied to resist specific environmental demands and make sure metal parts and products last. The primary function is to protect custom metal fabrication from the corrosive effects that accompany exposure to natural elements like rain, fog, or salt spray that could result in oxidation or contact with chemicals or harmful solvents.
Painting a metal surface creates a solid barrier to reduce contact between chemical compounds or corrosive materials. Industrial metal paints may come in a liquid, paste, or powder and are applied through various delivery systems. Wet paint is applied through spray or pump, whereas powder is applied through an electrostatic plating process. In all instances, once the paint hardens, it creates a protective skin on the custom metal fabrication that adheres to the metal and guards it against corrosion.
