With its streamlined frame and open-beam ceiling, this Aluminum Pergola looks stylish in any outdoor setting. The waterproof polyester canopy on top protects you from the elements, so you don't have to run back inside. When the weather is nice, you can control the canopy with a simple draw cord to let in as much sunlight as you want. Supported by aluminum columns, the gazebo is lightweight yet durable enough to stand the test of time. - H&O Direct Outdoor Aluminum Pergola for Patio Deck in Dark Grey
