This 9' Market Patio Umbrella is made of a lightweight aluminum frame with a durable powder coat finish-bronze. The 8-ribbed aluminum frame is secured to the pole using strong weather-resistant PVC materials sure to last for years of enjoyment on your patio or deck. The umbrella features a high-grade kevlar mesh cord that won't frey or break. This umbrella will tilt by using a button at the top of the mechanism below the canopy after the umbrella is fully opened. The canopy consists of 100% solution-dyed solefin fabric which will resist fading. We recommend using a 50 lb base weight for this umbrella under normal wind condition areas and adding the 30 lb additional base weight for high wind areas.
