【High Quality Guarantee】Made of high-density polyester (180gsm PES polyester), coated with PU coating, it is moisture-proof, mildew-proof, stain-resistant and odor-proof. Not recommended for storms, heavy rain or snow. 【99% Waterproof】The sun sail is coated with a waterproof PU coating. The fabric seams are heat-sealed to prevent leakage. It can withstand water pressure over 400kPa. 【95% UV Blocking】Blocks up to 95% of harmful UV rays and provides a shading rate of up to 90%, ensuring your privacy while protecting your family from UV damage. 【Easy to Install】Each corner is equipped with a 316 stainless steel D-ring with a rope. It is recommended to install the awning at an angle of 35° to 50°, leaving a space of 15 to 30 cm between the corner and the fixing point for easy hanging. 【Size Selection】This size is the straight-line distance between the D-rings. Due to the concave design (which provides better stability and support), the actual shading area may be smaller than the stated size. Please purchase the appropriate size according to your needs.
