It's an excellent question, as high humidity is a major concern for any outdoor furniture. You'll be pleased to know that our park benches are specifically engineered not just to survive, but to thrive in humid coastal areas, rainy climates, and places with significant temperature swings that cause condensation.
The secret lies in our material selection and protective finishes. For the frame and structure, we primarily use marine-grade aluminum. This aluminum alloy possesses inherent corrosion resistance, making it a standard in boat building. It simply will not rust, even when constantly exposed to moist, salty air. All our hardware—the bolts, screws, and brackets—is made from stainless steel for the same reason, ensuring the integrity of the bench's structure over the long term.
For the seating slats, we offer high-performance options. Our polymer lumber, made from recycled plastics, is completely impervious to moisture. It will not absorb water, warp, crack, or rot. It's also immune to mold and mildew growth. Alternatively, our benches featuring thermally modified wood undergo a chemical-free process that permanently alters the wood's cellular structure, making it highly stable and much less susceptible to moisture absorption and biological decay than untreated timber.
Furthermore, every metal component receives a robust protective coating. Aluminum parts feature a durable powder coating that acts as an additional barrier, while any other metals have specialized, multi-layer finishes designed to prevent oxidation. This comprehensive approach ensures that from the largest beam to the smallest screw, every part is protected.
The result is a park bench that maintains its structural integrity, aesthetic appeal, and comfort for years, with minimal maintenance required. You can have confidence that our benches will remain a beautiful and reliable public amenity, even in the most demanding, humidity-prone locations.
