This 12x20 permanent gazebo features an innovative double roof system—16mm thick resin lower roof and galvanized steel upper roof—boosting snow load capacity to 35lbs/sq.ft (vs. standard 22lbs/sq.ft), reducing rain noise, improving winter heat insulation (ideal for hot tubs), and preventing shipping deformation. Its reasonably sloped roof and water gutters ensure quick rain drainage, avoiding pooling and structural damage. Equipped with 180G PU-coated privacy curtains (for rain, warmth, privacy) and breathable netting (to keep insects out), plus a double-track system for independent operation of curtains and netting. The robust powder-coated alloy steel & aluminum frame, 3.94x3.94inch thick posts, and pre-drilled base (with plastic cover to prevent rust and protect kids/pets) ensure durability and safety. Internal roof mesh blocks debris/insects between double layers, and two J-hooks let you hang fans, lights, or decorations, making it perfect for BBQs, hot tubs, dining, or as an outdoor parlor/carport, with 60MPH wind resistance and all-weather durability for year-round use.
