Yes, at our outdoor bench factory, we prioritize durability and longevity by using high-grade stainless steel for all screws and hardware components. Specifically, we employ 304-grade stainless steel, which is widely recognized for its excellent resistance to rust and corrosion, especially in outdoor environments exposed to moisture, rain, and humidity. This material contains chromium and nickel, forming a passive protective layer that prevents oxidation and staining over time. Additionally, we apply a secondary passivation treatment to further enhance the corrosion resistance of our fasteners. Unlike standard galvanized or zinc-plated alternatives, stainless steel hardware does not peel, chip, or develop surface rust under normal weather conditions. However, it is important to note that no material is completely immune to rust in extreme environments—such as coastal areas with salt spray or industrial zones with chemical pollutants. In such cases, we recommend periodic rinsing with fresh water and applying a light oil coating to maintain the stainless steel’s protective layer. For customers with specific concerns, we also offer marine-grade 316 stainless steel as an upgrade option. Rest assured, our commitment to rust prevention goes beyond the hardware: we design our benches with drainage features to minimize water pooling around fasteners. This comprehensive approach ensures that your outdoor bench remains structurally sound and visually appealing for many years. If you have further questions about material certifications or testing results, our engineering team is always available to provide detailed documentation.
