At our outdoor bench factory, durability and longevity are non-negotiable. That’s why we exclusively use rust-proof screws designed to withstand the harshest weather conditions. The answer to your question is clear: yes, all our screws are corrosion-resistant. Specifically, we rely on 304-grade stainless steel screws for standard outdoor benches. This material offers excellent resistance to moisture, UV rays, and temperature fluctuations without sacrificing structural strength. For benches exposed to coastal or high-humidity environments, we upgrade to 316-grade stainless steel, which contains molybdenum for added protection against chloride corrosion.

In addition to stainless steel, we also employ coated carbon steel screws in some non-critical internal joints. These screws feature a corrosion-resistant coating, such as zinc plating or epoxy-based finishes, which provides an extra barrier against rust. However, for all visible and structural connections—seat slats, leg assemblies, and armrests—we use solid stainless steel. No coated or plated screws ever touch outdoor-exposed surfaces in our designs.

Every batch of screws undergoes a salt spray test to verify their rust-proof performance before assembly. We also ensure that screws are compatible with pressure-treated lumber or composite materials used in bench construction, preventing chemical reactions that could accelerate corrosion. So, when you ask us about screws, the answer is simple: we never compromise on rust-proof quality. Your outdoor bench will stand strong, rain or shine, for years to come.
