When selecting benches for public spaces, maintenance is a crucial factor. Wooden benches, often crafted from durable hardwoods like teak or oak, require a more hands-on approach. They need regular inspections for splinters, cracks, or rot, especially at ground-contact points. Annual sealing or staining is recommended to protect against moisture and UV damage, preventing graying and decay. While minor repairs like sanding and tightening bolts are straightforward, major rot replacement can be costly. Their lifespan, typically 10-25 years, heavily depends on this consistent upkeep.
Metal benches, commonly made from aluminum or powder-coated steel, offer a different care profile. Their primary enemy is corrosion and finish degradation. Powder-coated steel requires checks for chips or scratches that can lead to rust, necessitating touch-up paint. Aluminum is naturally rust-resistant but can oxidize and stain. Maintenance usually involves washing with mild detergent and rinsing to remove pollutants and debris. Structural welds should be inspected for integrity. With minimal upkeep, metal benches can last 25+ years, but once corrosion sets in, repair is often less effective than replacement.
The choice hinges on priorities: wood offers classic warmth but demands cyclical care, while metal provides a "lower-touch," long-life solution but can suffer from irreversible corrosion. The local climate, vandalism potential, and available maintenance budgets are the final deciding factors.
