This gigantic market umbrella has a nautical-inspired design and high-end appeal. Its aluminum telescopic mast is reinforced with an internal galvanized steel stem. The centerpost and ribs have an anodized silver finish that inures the metal against corrosion and water damage. The convenient crank lift system is simple to operate and takes only seven turns to open the outdoor umbrella.

The spacious single vent canopy comes in three sizes and two shapes and provides shade for up to 266 square feet of space. It's covered in high performance synthetic polyester or acrylic fabric that is solution-dyed to ensure fade-resistance. The all-weather textiles are available in a wide variety of chic neutral tones and bold colors from premium outdoor brands such as Sunbrella®, Outdura® and Obravia®.

Due to its large scale, the Astral patio umbrella requires substantial support. Shademaker recommends using a concrete or in-ground permanent mount, but a freestanding base is also available. The steel base frame accommodates sixteen inch stone pavers or weights that can be purchased at your local home improvement warehouse store. The minimum base weight ranges from 400-700 pounds, but you can be certain that your outdoor umbrella is stable even in windy conditions.

Astral is designed to close over tables and chairs, so it's a great choice for large al fresco dining settings in residential and commercial environments. It also includes a protective cover so you can safeguard your umbrella from the elements and lengthen its useful life.
