What are the effects of heavy rainfall on the structural integrity of canvas benches?

Heavy rainfall can significantly affect the structural integrity of canvas benches, leading to various forms of damage over time. Prolonged exposure to rain causes the canvas fabric to absorb moisture, which weakens its fibers and reduces its durability. This can result in sagging, stretching, or even tearing of the material. Additionally, the metal or wooden frames supporting the canvas may rust or rot when repeatedly exposed to water, further compromising the bench's stability. Mold and mildew growth is another common issue, creating unpleasant odors and potential health hazards. To mitigate these effects, it's advisable to use waterproof covers or store canvas benches indoors during heavy rain seasons. Regular maintenance, such as cleaning and drying the fabric, can also extend the lifespan of these outdoor furniture pieces.
