【BLOCK UV RAYS】The high quality HDPE sun shade sail contains additional anti-UV additives, blocking harmful UV rays 95% and thus protecting your skin from harmful rays. The high-quality, breathable fabric prevents annoying heat build-up under the sun cover. 【Upgraded Material】The sail shade is made of 185 g/sqm high-density polyethylene (HDPE) (not spliced). It has the properties of high tensile strength, aging resistance, corrosion resistance and radiation resistance. For the better tear resistance, we sewed 60cm long and 18g thick tape in the corners. There are durable 304 stainless steel D-rings at each corner, which have been stitched across multiple times for excellent stability. 【Curved Design】The curved design allows for better tensioning of the shade sail to prevent wrinkles and sagging. Edges are stitched on both sides to prevent wear and deformation. Due to the curved sides, the actual shaded area is slightly reduced. Please note that our shade sails are not waterproof. 【Easy to Install】Colegence shade sails are quick and easy to assemble. We provide 3-4 thicker ropes. You need to leave a distance of 12 to 18inch between the attachment point and the sun shade sail. Each shade sail must be installed at an angle of 20 to 40 degrees with maximum tension and tightened regularly. 【Application】Colegence patio cover brand provides natural sun protection in many scenarios.
