A durable patio umbrella will have a strong frame and high-quality canopy fabric. Popular frame materials include wood, steel, aluminum, and fiberglass, while fabrics include acrylic (like Sunbrella), polyester, and olefin. If the umbrella shares a wind rating, the higher the wind rating, the more durable the umbrella is likely to be. Also, look into the warranty; sturdy umbrellas aren’t afraid to offer one.
