The gazebo features a galvanized steel roof that is fade and rust resistant, strong enough to withstand heavy snow and wind, and blocks glare and harmful UV rays. The EROMMY large gazebo with pre-drilled base is designed for various uneven ground and can be installed in different outdoor environments. The professional drainage system is designed to allow water to flow from the top edge of the aluminum gazebo to the poles and the ground, which can enhance the snow load and reduce the trouble during the rainy and snowy seasons.
