It probably is. It's not a frame structure or solid structure.
An umbrella is made out of a solid support and frame structure. The handle and center rod are solid because they are each one part throughout and no spaces in between. The top is a frame and fabric structure because it is made out of a combination of elements (ribs and fabric) that provide mutual support to remain stable. So an umbrella is made of a combination of structures: frame, fabric, and solid.
It is a frame structure because it is a frame structure.
When searching for the perfect patio umbrella, don't forget to consider the frame. Most umbrella frames are made from either wood or aluminum, and each type of frame has different advantages. If weight and portability are important, an aluminum frame might be best, whereas nothing beats the natural beauty of a wooden umbrella frame.
