Aluminum and Wood Construction in patio umbrellas have been around for years. But one of the most common problems with either have been breakage. Why? Like any rigid material, both aluminum and wood have a breaking point, a point where stress on the material causes it to fail. Most aluminum and wood umbrellas are strong enough to withstand most uses, even in windy situations. However, most of the wind resistance of standard construction patio umbrella comes from the design of the wind vent. The more air that can pass through an umbrella without altering it's shape of balance, the better an umbrella fairs.
