Great question. Coastal environments are notorious for accelerating wear and tear on outdoor furniture, but our urban benches are specifically engineered to handle the challenges of salt spray, high humidity, and constant exposure to the elements.
First, we prioritize material selection. All metal components—from the frame to the armrests and leg supports—are made from marine-grade 316 stainless steel. Unlike standard 304 stainless, 316 contains molybdenum, which provides superior resistance to pitting and crevice corrosion caused by chloride ions in salt spray. For the seating surface, we use powder-coated aluminum or high-density polyethylene (HDPE). The powder coating is applied through a multi-layer process that includes a zinc-rich primer and a UV-stable topcoat, creating a barrier that withstands salt attack. HDPE, on the other hand, is naturally resistant to moisture and UV rays, so it won’t rust, rot, or delaminate even after years of oceanfront exposure.
We also account for design details. Wherever possible, we eliminate exposed fasteners by using welded joints or concealed stainless steel hardware. This prevents saltwater from seeping into crevices and initiating corrosion from the inside out. Drainage channels are built into the bench slats to prevent standing water, which can accelerate salt concentration and damage over time.
In real-world testing, we installed a batch of these benches on a public boardwalk in Miami, Florida. After two years of constant salt spray, hurricane-force winds, and subtropical UV, the benches showed only superficial fading of the color coating—no structural degradation, no rust spots, and no loosening of joints. We also have installations in coastal cities like Sydney, Barcelona, and San Diego, where feedback consistently highlights their longevity.
To maintain performance, we recommend a simple rinse with fresh water every few months to wash away salt buildup. That’s it. No special coatings or sealants needed.
So, to answer your question directly: our urban benches hold up extremely well in coastal areas with salt spray. They’re built to last 15 to 20 years in these conditions, backed by our material guarantees and field-tested data. If you have a specific coastal installation in mind, we can even suggest a custom finish or add-on anchor system for extra wind resistance. Just let me know.
