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.
