Park chairs are exposed to harsh weather conditions, yet their coatings remain intact for years. The secret lies in advanced materials and application techniques. Manufacturers use powder coating or specialized paints containing UV inhibitors and rust-resistant additives. These coatings bond tightly to metal or wood surfaces through processes like sandblasting or priming. Regular maintenance, such as cleaning and minor touch-ups, further extends their lifespan. High-quality park chairs also feature designs that minimize water pooling, reducing corrosion risks. By combining durable materials, protective layers, and smart engineering, these chairs withstand daily wear while retaining their aesthetic appeal.
