It's a common sight in many cities: benches slowly succumbing to rust and decay. Our urban benches tackle this challenge through multiple protective layers. The secret starts with the materials. We use heavy-duty aluminum alloys that naturally resist corrosion, along with powder-coated steel. This coating isn't paint; it's a dry electrostatically applied polymer that's thermally bonded to the metal, creating a shield far more resilient than traditional finishes.
For structural steel components, we employ hot-dip galvanization. This process involves immersing the steel in molten zinc, creating a metallurgical bond that sacrifices itself slowly to protect the core material—a process called cathodic protection. Even if scratched, the zinc continues to guard the exposed area.
We also integrate sustainable hardwoods like thermally modified ash or oak, where heat treatment alters the wood's cellular structure to repel moisture and insects without toxic chemicals. For metal joints and fittings, we use stainless steel fasteners to prevent galvanic corrosion.
The design itself fights decay. We engineer benches with slanted seating surfaces that shed rainwater quickly and avoid moisture-trapping pockets. Regular maintenance involves simple cleaning rather than sanding and repainting. This multi-pronged approach—from material science to intelligent design—ensures our public seating remains safe, attractive, and rust-free for decades, transforming urban landscapes with enduring quality.
