Park chairs are exposed to harsh weather conditions, making bolt corrosion a common issue. To combat this, manufacturers use several effective methods. Galvanized bolts are a popular choice, as they are coated with zinc to create a protective barrier against moisture and oxygen. Stainless steel bolts are another durable option, resistant to rust due to their chromium content. Additionally, some park chairs feature powder-coated or painted bolts, adding an extra layer of protection. Regular maintenance, such as applying anti-corrosion sprays, further extends their lifespan. These strategies ensure park chairs remain sturdy and safe for public use over time.
