Our rectangle shade structures come with 14 fabric color choices so you can create the look that your facility deserves. We utilize a four-post steel frame and the shade canopy is tensioned over a hip and ridge design. We have over 100 standard variations of our rectangle shades with an option of creating custom sizes if that's what you require. For customers in coastal regions or northern climates, we recommend adding our optional Glide Elbowâ¢ accessory which makes it easier to install, remove, and tension the shade canopy. Whether you're adding shade to a park, playground, or pool deck the rectangle shaped canopy is a solid choice.
