Aside from choosing the right materials, regular maintenance is essential. Periodically cleaning hardware surfaces to remove salt, dust, and accumulated water can effectively delay rust formation. Additionally, opt for accessories designed with drainage holes or channels to help eliminate water buildup and reduce the risk of corrosion.
