Park chairs are designed to withstand harsh outdoor conditions, and preventing fastener corrosion is a key factor in their durability. Manufacturers use several strategies to protect fasteners from rust and degradation.

First, high-quality materials like stainless steel or galvanized steel are commonly used for fasteners. These metals resist oxidation and moisture damage, ensuring long-term stability. Additionally, protective coatings such as zinc plating or powder coating create a barrier against water, salt, and UV exposure.

Another method is the use of plastic or rubber washers, which reduce metal-to-metal contact and prevent galvanic corrosion. Proper design also plays a role—elevated fasteners and drainage holes minimize water accumulation.

Regular maintenance, including inspections and lubrication, further extends fastener life. By combining these techniques, park chairs remain sturdy and safe for years, even in challenging weather conditions.
