Anchoring a poolside deck or backyard dining spot this 10 x 10 ft arched top metal pergola blends architectural curves with a retractable sun shade canopy. The heavy duty steel frame supports gently vaulted beams that lend the structure a pavilion look while the canopy top slides along the beams to block direct sun or retract for an open-sky view. The rust-resistant powder-coated finish stands up to rain and humidity and the four sturdy posts free-stand without footings.
