The sun protection factor of the outdoor canopy is UV50+ and the waterproof factor is PU2000MM, providing a cooler, safer, and more comfortable environment for outdoor weddings, parties, exhibitions, etc. Stable and Wind-resistant: Our frame for the 10×20 canopy tent is made of thickened alloy steel, with powder coating on the outside of the steel frame, which is durable, rust-proof, and corrosion-resistant. In addition, the cross-tube connection at the top of the canopy tent frame adopts an upgraded reinforced design, which is more stable and wind-resistant than traditional 10×20 canopy tents. Larger Space: The 10×20 pop up canopy tent has 200 square feet of shade area and can accommodate 15-25 people at the same time.
