This double-sided patio umbrella features a high-quality 180g polyester canopy that provides optimal shade and Uv protection, with waterproof and fade-resistant fabric to maintain color vibrancy. The wide stable base includes a cross metal design and sandbags that can be filled with up to 180 lbs of sand for added weight and security. Thickened steel pipes with a powder-coated finish resist rust and corrosion, while 12 heavy-duty ribs deliver superior wind resistance in any weather. A smooth hand-crank mechanism allows for easy opening and closing, and the double-sided design creates a larger shade area-ideal for social gatherings. Durable double stitching and a fixation strap ensure a secure canopy closure.
