Our iron double roofs can enhance the air circulation in the hardtop gazebo, which is beneficial to resist strong winds. The use of metal roof coating can effectively block UV rays and withhold heavy snow, at the same time has the effect of anti-corrosion and waterproof. The 4 rustproof iron pillars of our outdoor gazebo are designed with a triangular structure, bolt connections, and welded T-frame making them more stable. This 10'X12' weather-resistant gazebo is built to withstand the elements for year-round use and is perfect for a variety of events. This patio gazebo has a double-track system that allows for double-layered sidewall and sliding each layer with ease. Two side zippered privacy curtains and mosquito netting protect you from the insects, sun, and rain while still having full airflow and visibility. Because of hooks, you can install lights and fans to decorate the gazebo. The large size allows your family and friends to enjoy the great outdoors in your patio, backyard, deck, etc. Our hardtop garden gazebo will come with 3 boxes, the installation will take approx. 5 hours for 2-3 people.
