How does salt spray corrosion affect metal parts in rattan outdoor planters?

Salt spray corrosion is a common issue for metal parts used in rattan outdoor planters, especially in coastal or high-humidity environments. When exposed to salty air or moisture, metal components like screws, frames, or brackets can undergo oxidation, leading to rust and structural weakening. This corrosion not only diminishes the aesthetic appeal but also compromises the durability of the planter.

To mitigate this, manufacturers often use corrosion-resistant materials such as stainless steel or aluminum with protective coatings like powder coating or galvanization. Regular maintenance, including cleaning and applying anti-rust treatments, can further extend the lifespan of metal parts in rattan planters. Understanding these effects helps in selecting and caring for outdoor furniture to ensure long-term performance.
