In humid environments, such as coastal areas, regions with frequent rainy seasons, or spaces like bathrooms, doors and windows are often exposed to moisture or even salt spray, which can easily cause metal parts to rust. Once hardware accessories rust, it not only affects their appearance but also compromises the lifespan and safety of the doors and windows. Therefore, when selecting door and window accessories, it’s crucial to prioritize anti-rust performance.
I. Key Considerations When Purchasing
Choose materials with strong corrosion resistance. Different metals vary significantly in their ability to resist rust in humid environments. Opting for lower-priced options may lead to higher maintenance costs in the long run. Additionally, pay attention to the surface treatment process—even with good materials, inadequate surface protection can still lead to rust. Lastly, select products based on the specific environment: for example, coastal areas require strong resistance to salt spray, while bathrooms primarily need protection against daily moisture.
II. How to Choose Main Accessories
For commonly used hardware such as hinges, handles, and locks, 304 stainless steel is highly recommended due to its high chromium and nickel content, which provides excellent corrosion resistance. Alternatively, 201 stainless steel is also a viable option. While zinc alloy is more affordable, it must have a thickened coating to withstand generally humid environments. In terms of surface treatment, electrophoretic coating offers better rust protection than powder coating or ordinary electroplating due to its uniform texture and strong adhesion.
Although sealing strips are not made of metal, they play a critical role in the overall sealing and moisture resistance of doors and windows. EPDM (ethylene propylene diene monomer) rubber is the preferred choice due to its excellent aging resistance, UV resistance, and moisture resistance. Silicone offers good elasticity, but it’s important to choose a water-resistant variant specifically designed for humid environments.
Small components like screws and bolts are often the weak points in rust prevention. In particularly humid or high-salt environments, 316 stainless steel screws are recommended. If budget constraints exist, hot-dip galvanized screws can also provide a certain level of protection.
Moving parts such as pulleys and hinges should not be overlooked. High-quality pulleys typically feature nylon wheels paired with stainless steel shafts, ensuring both wear resistance and rust prevention. For hinges, fully stainless steel structures are ideal to avoid exposing internal iron cores, which could lead to rust.
III. Additional Anti-rust Considerations
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.
In humid environments, selecting anti-rust hardware is key to ensuring the durability and aesthetics of doors and windows. If you’re looking for reliable and long-lasting products, consider 3H Hardware—specializing in the research and development of aluminum door and window hardware, their products are well-suited to harsh environments like high humidity and high salinity, providing excellent support for home safety and aesthetics.
