Aerodynamically designed, their strength is in the patented Swivel. It’s the only one of its kind that permits the canopy of the umbrella to easily swivel into the wind, rather than being stationary and causing updrafts. Our swivels are custom made from aluminum to provide the utmost durability and stability for the umbrellas. We only use high grade extruded aluminum in production. Our umbrellas have been known to withstand hurricane conditions. In the past, we’ve tested one against a wind tunnel test, passing at 70 mph! Unlike fiberglass umbrellas, Arizona Aluminum Umbrellas have a reputation for withstanding high winds and deflecting heat.
