Urban benches in coastal areas face unique challenges from salty air, which accelerates corrosion and deterioration. The performance largely depends on material selection and protective treatments. Stainless steel benches, particularly grades 304 and 316, offer excellent resistance, with 316 providing superior protection in harsh marine environments. Powder-coated aluminum benches combine lightweight durability with effective corrosion resistance when properly sealed.
Traditional wood benches require pressure treatment with ACQ or micronized copper azole preservatives, while tropical hardwoods like ipe naturally resist moisture and salt damage. Modern solutions include marine-grade polymer lumber and concrete benches with proper sealing compounds.
Regular maintenance proves crucial - including freshwater rinsing, inspection for damage, and timely refinishing. Coastal municipalities should prioritize benches with minimal joints, shielded fasteners, and non-absorbent surfaces. With appropriate material selection and maintenance protocols, urban benches can maintain both functionality and aesthetic appeal despite constant exposure to salty coastal air.
