A canopy is an overhead roof or else a structure over which a fabric or metal covering is attached, able to provide shade or shelter from weather conditions such as sun, hail, snow and rain. A canopy can also be a tent, generally without a floor. Architectural canopies include projections giving protection from the weather, or merely decoration. Such canopies are supported by the building to which they are attached and often also by a ground mounting provided by not less than two stanchions, or upright support posts.
Canopies can also stand alone, such as a fabric covered gazebo or cabana. Modern frame materials offer high strength-to-weight ratios and corrosion resistance. The proper combination of these properties can result in safe, strong, economical and attractive products.
