What is the purpose of corrosion-resistant coatings on chain-link hardware?

To stain the fence for aesthetic reasons

To improve magnetic properties

To reduce maintenance costs

To prevent rust and extend life, especially in harsh environments

Corrosion-resistant coatings on chain-link hardware are applied to act as a protective barrier between the metal and corrosive elements like moisture, oxygen, and salts. This shielding slows or stops rust, helping the hardware retain its strength and appearance for a longer period, especially in environments that are harsh or exposed to the elements. In settings with coastal air, heavy rainfall, or chemical exposure, the protective coating becomes even more important to prevent rapid deterioration and costly replacements. While a coating can also contribute to a neater look and may reduce maintenance needs over time, its primary purpose is preventing rust and extending the life of the hardware.
