Corrosion Resistance
The ability of a metal or coated surface to withstand degradation by moisture, chemicals, salt, or galvanic action. Coating selection, such as powder coat, galvanizing, anodizing, or plating, is the primary method for engineering corrosion resistance into fabricated parts.
Corrosion resistance is not a property you can achieve through manufacturing alone, it must be engineered into your design and coating strategy from the beginning. The environment where your part will operate directly dictates your coating choice: atmospheric industrial environments may be adequately served by powder coating and primer, while marine or chemical applications demand hot-dip galvanizing or multi-layer wet paint systems.
Material selection also plays a critical role, stainless steel naturally resists corrosion through passivation, while bare carbon steel requires protective coatings to survive outdoor exposure. Engineers routinely specify salt spray testing to validate that their chosen coating system will deliver the required service life.
By combining proper material selection with appropriate finishing techniques, you can design parts that maintain structural integrity and appearance for decades.
