【New High-density PE Material】 Sun shade sail is made of 100% 185gsm New high-density polyethylene(HDPE) material, not recycled material. New PE material has improved durability and exhibits higher strength to withstand prolonged exposure to sunlight, minimizing the risk of fading, embrittlement or degradation over time, giving it a longer lifespan and saving on maintenance costs. 【Breathable fabric & Not Wateproof】 The breathable fabric allows cool breezes to pass through, creating a comfortable and well-ventilated space. It is not waterproof and allows rainwater to pass through, so there is no accumulation of water. Excessive water accumulation on a shade sail can put stress on the fabric and support structure, causing damage or failure. Recommended to remove the awning during storms and typhoons. 【Blocks Harmful UV Rays】 90% Shading rate and protects against up to 95% harmful UV rays. Ideal sun shade canopy solutions perfect for patio, lawn, garden, backyard, pond, pool, dooryard, terrace, balcony, carport, BBQ areas or another outdoor area. You can enjoy outdoor activities while staying safe from sunburn and skin damage. 【3 Sewing Threads Reinforced Edges】A full strip of webbing is sewn inside the sail's edge stitching, and 3 sewing threads reinforced edges increase the edge's tear resistance, reducing the risk of tearing or fraying in areas prone to stress or tension. The D-rings at the 4 corners are made of 304 stainless steel thicker than ordinary D-rings and are more solidly installed. 【Package & Installation】 Includes one 10' x 13' Brown rectangle sunshade sails and 4 durable ropes (2m/6.56ft). Measure and clean the area where the sun sail shades are to be installed. Allow 1-2ft of clearance between the anchor point and the sail shade canopy for mounting hardware/ropes or hooks. Tips: Duerer sun shades sail cover have curved sides to increase tensile strength and prevent drooping.
