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.
Canopies can also stand alone, such as a fabric covered gazebo
or cabana. Fabric canopies can meet various design needs. Many modern fabrics
are long-lasting, bright, easily cleaned, strong and flame-retardant. This
material can be vinyl, acrylic, polyester or canvas.[ 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.
