The Ultimate Heavy-Duty Shade for Your Outdoor Oasis Is this umbrella built to last? Yes. The Patio Kingdom Perli series focuses on structural integrity. We use powder-coated iron for the pole and all 12 ribs to provide a high-strength frame that resists bending and swaying. It’s designed for users who prefer the solid, weighted feel of a traditional metal market umbrella. How does it handle the wind? This large rectangular umbrella is engineered for high-wind durability. In addition to the heavy-duty iron frame, we include a complete base system with sandbags. When properly weighted (filling with 135-150 lbs of sand), it is designed to remain steady even in gusts over 40 mph. Product Highlights: Pole Diameter: 1.9" (Fits most standard patio tables with 2" holes). Lighting: 48 Solar LEDs for 6-8 hours of nighttime glow. Vents: 3 Top vents for enhanced airflow and wind pressure release. Operation: Smooth metal crank lift.
