An umbrella consists of a foldable piece of the cover attached to metal ribs, which is typically installed to a stand or post made of wood or metal. Its purpose is to provide portable shelter under sunlight and rain. Umbrellas are normally a basic hand-held equipment for individuals. There are basically 2 types of umbrellas: one is completely foldable, and the other is non-collapsible. Some people divide it into physically opened (open it by hands) and automated (open at the press). A bigger umbrella that can fit a group of people is a trend nowadays. They’re regularly used outside of the building, next to outdoor sofa sets, patio dining sets or other garden furniture for shading.
