Extra large outdoor sunshade umbrella! The 450cm double-sided patio umbrella will provide you with an oversized shade area for outdoor activities in hot weather. It can accommodate large dining tables, chairs and multiple people, making it ideal for outdoor gatherings on decks, poolsides, courtyards and more. In addition, the umbrella pole has an easy to operate manual crank, allowing you to easily open and close it within seconds. To extend the service life of our umbrella, we use high-quality polyester fabric, which is not only waterproof and rust-proof, but also breathable. In addition, the roof is ventilated to improve air circulation and stability. What’s more, we provide a metal base and two sandbags for filling the base to further enhance the windproof performance of the umbrella when it is used outdoors. The entire umbrella is made of powder-coated metal frame, which ensures a long period of time.
