Our aluminum patio umbrellas are umbrellas the have an aluminum frame. The frame style may actually be a market umbrella or a patio umbrella. The distinction in a classic market umbrella is the thicker ribs, a wind vent, and typically the umbrella does not have a valance. A true patio umbrella has thin aluminum rods and has a free-hanging valance. Since most consumers use patio umbrella to describe any outdoor umbrella, we use patio umbrella to describe all our outdoor umbrellas. We have residential and commercial aluminum patio umbrellas where the canopy size coves 6' to 11'. Our aluminum commercial umbrellas do not tilt, and made with thicker aluminum than a residential umbrella. Our residential umbrellas are design to bring added shade comfort with the tilting feature.
