Yes — our outdoor bench factory uses marine-grade hardware on every single model. While standard stainless steel or galvanized fasteners might survive an occasional rain shower, they will quickly succumb to the relentless salt-laden air of a coastal town. That is why we refuse to cut corners. All bolts, screws, hinges, and mounting brackets are manufactured from 316 stainless steel or marine-grade aluminum. 316 stainless steel contains molybdenum, which gives it superior resistance to chloride corrosion. Additionally, every exposed fastener receives an extra layer of protection through our passivation and powder-coating processes. We validate our hardware with rigorous salt spray testing according to ASTM B117 standards, simulating years of coastal exposure in a matter of weeks. Our benches have endured more than 1,000 hours in the salt spray chamber without showing any red rust or structural weakening. We also use UV-stabilized plastic caps for any recessed hardware, preventing moisture from pooling around screw heads. When you choose our benches for a seaside boardwalk or a harbor-front plaza, you can be certain that every component is built for marine environments. We do not make "coastal versions" — everything is marine-grade as standard. So the answer is an unequivocal yes: our factory uses marine-grade hardware, and we proudly stand behind the rust-proof performance of every bench we ship.
