Our rectangle sun shade sail canopy is made of 100% high-density polyethylene shade fabric, more healthy and safe. The sunshade sails have a 90% shading rate, which can resist up to 95%-98% of harmful ultraviolet rays, while effectively reducing heat, protecting your garden, terrace, swimming pool, barbecue area, coffee bar, or other outdoor areas in the hot Keep cool in the weather. The breathable fabric design allows cool air to penetrate the outdoor awning sail, providing a ventilated, comfortable and well-ventilated space. The breathable fabric allows water to go through freely, and there is no accumulation of water on rainy days (so it is not waterproof). The solar sail is slightly curved, so it can be stretched to prevent sagging in the middle. There are 600 pounds of durable stainless steel D-rings at each corner of the shade sail, making the rectangular shade sail easy to connect to any strong connection point. The 600-pound polyester belt stretches across the edge of the solar sail to maintain a strong pull. (This shade cloth does not include hardware tools and ropes)
