The 1.5-inch diameter all-iron umbrella pole is very stable, and the six sturdy steel ribs support the umbrella canopy well. The surface of the metal rod is coated with an anti-oxidation coating to prevent rust and corrosion. Note: When not in use or in inclement weather, we advise storing the parasol in a cool and dry indoor place. There are 18 LED lights on the ribs of the parasol. It is charged by the solar panel on the top of the umbrella to save energy and promote an environmentally friendly lifestyle. In the evening, you can have a cocktail party, dinner party, chat and other leisure and entertainment outdoors with your family and friends.
