When saltwater spray comes into contact with specific metal products, it can lead to corrosion over time, particularly within a time frame of five to seven years. This is primarily due to the chlorides present in the saltwater, which accelerate the corrosion process, especially in reactive metals such as iron and steel.

The presence of salt can create a highly corrosive environment that promotes the formation of rust and other corrosion types. For metals exposed to saline conditions—like those found near oceans or in industrial settings—this time frame serves as a guideline for what can happen if protective measures are not in place. Ultimately, while corrosion may not happen immediately, the risk significantly increases with prolonged exposure, leading to deterioration of the material's integrity.

Understanding this timeline is crucial for construction and maintenance planning, as it highlights the need for protective coatings or the selection of more corrosion-resistant materials when working in saltwater-prone areas.
