What to Consider When Choosing the Best Cantilever Umbrella
Common cantilever canopy fabrics include acrylic, Sunbrella, polyester, and olefin.
- Acrylic: Acrylic is a soft and versatile fabric that is easy to dye in a range of colors and patterns. Acrylic canopies retain their shape and resist wrinkling, making them a great pick for decorative and protective umbrellas.
- Sunbrella: Sunbrella is a durable UV- and weather-resistant acrylic fabric that holds up to outdoor conditions without fading. Designed for outdoor use, it is also mold and mildew resistant and easy to wipe clean.
- Polyester: Polyester is a cost-friendly fabric that is quick to dry. To offer proper protection and resist sun damage, look for a UV-treated option.
- Olefin: Olefin offers superior UV resistance and is a quick-drying fabric ideal for the outdoors. It is also easy to wipe clean of mold or mildew.
Popular frame materials include stainless steel, aluminum, and fiberglass.
- Stainless steel: Sleek and modern stainless steel is durable and naturally corrosion resistant, making it a great pick to handle rain and moisture. However, saltwater can cause steel to corrode, which is a possibility in seaside locations.
- Aluminum: Aluminum is sturdy, lightweight, and affordable. Most aluminum frames are powder coated or anodized to make them corrosion resistant. They are available in a variety of color and finish options.
- Fiberglass: Fiberglass tends to be a costlier option, but this durable material is worth the cost in areas with a lot of inclement weather. It is lightweight and performs well in windy conditions, offering more flexibility than stainless steel or aluminum. Fiberglass also won’t rust or rot in stormy and wet climates. Some umbrellas feature fiberglass ribs under a metal framing to combine the sturdiness of both materials.
One way to measure the UV resistance of a patio UV umbrella is the UPF (ultraviolet protection factor) rating. This rating refers to the fabric’s ability to block a certain amount of UV rays. A higher UPF rating means better protection, with most ratings ranging between 15 and 50+. A UPF 15 fabric blocks around 93.3 percent of UV radiation, while a 50+ UPF fabric blocks around 98 percent of UV radiation.
