Why are stainless steel outdoor chairs less prone to insect damage compared to wood?

Stainless steel outdoor chairs are less prone to insect damage compared to wood due to their non-organic composition. Unlike wood, which contains cellulose and moisture—key attractants for termites, ants, and other pests—stainless steel is inorganic and lacks nutrients that insects feed on. Additionally, steel does not rot or decay, eliminating habitats for pests. Its smooth surface also prevents insects from burrowing or nesting, making it a durable, low-maintenance choice for outdoor furniture. Wood, on the other hand, requires regular treatments to deter pests, whereas stainless steel naturally resists infestation.
