About this article 【98% UV Blocking】- Blocks 98% of harmful UV rays (UPF 50+), protecting your skin from harmful radiation. Allows refreshing breezes and rain to pass through for better ventilation and a comfortable space (it is not waterproof). Do not use in inclement weather 【High Quality Guaranteed】- The shade sail is made of 185 g/m² high-density polyethylene (HDPE) fabric (unspliced). It features high tensile strength, aging resistance, corrosion resistance, and radiation resistance. It has strong stitched seams and durable 304 stainless steel D-rings at each corner. 【Practical and Aesthetic Design】- The curved design showcases artistic beauty. It stretches the shade sail better to prevent creasing and sagging. All edges have double-layered reinforced stitching to prevent fraying and edge distortion. Due to the curved sides, the actual shaded area will be slightly reduced. Various colors and sizes are available. 【Easy to Install】- Measurements are taken from D-ring to D-ring. Allow a 30-45cm gap between the fixing point and the shade sail for installing hardware/hooks/ropes. (Fixing kits sold separately, not included). Waterproof shade sails should be installed at a 20-40 degree angle with maximum tension to allow water runoff. 【Application】- Widely used for gardens, patios, yards, backyards, courtyards, porches, barbecue areas, driveways, entrances, lawns, plant shade, terraces, parks, swimming pools, carports, boats, camping, ponds, or other outdoor occasions. Make your private patio safe, cool, and fabulous.
