Park chairs are exposed to various weather conditions, including acid rain, which can cause significant damage over time. To prevent corrosion and deterioration, manufacturers use several protective measures.

First, park chairs are often made from weather-resistant materials such as aluminum, stainless steel, or specially treated wood. These materials naturally resist rust and decay. Additionally, metal chairs are coated with powder coatings or galvanized finishes, creating a barrier against moisture and acidic elements.

Another method involves using plastic or composite materials, which are inherently resistant to acid rain. These materials do not corrode and require minimal maintenance. For wooden chairs, sealants and water-repellent stains are applied to protect the surface from moisture absorption and chemical damage.

Regular maintenance, such as cleaning and reapplying protective coatings, further extends the lifespan of park chairs. By combining durable materials and proactive care, park chairs remain functional and aesthetically pleasing despite exposure to acid rain.
