How do you design outdoor benches to be resistant to damage from airborne pollutants?

Designing outdoor benches to withstand airborne pollutants requires careful material selection and protective measures. Opt for corrosion-resistant metals like aluminum or stainless steel, or choose treated hardwoods and high-density plastics that resist chemical degradation. Apply UV-resistant and anti-pollution coatings to shield surfaces from acid rain, smog, and industrial fallout. Consider smooth, non-porous surfaces that allow easy cleaning of pollutant buildup. Incorporate drainage in the design to prevent water pooling that can trap pollutants. Regular maintenance with pH-neutral cleaners helps preserve the bench's protective layers. For urban areas with heavy pollution, modular designs allow easy replacement of affected components. These strategies create durable benches that maintain functionality and appearance despite environmental challenges.
