1.VIRGIN, UV STABLIZED COMPOUND THICK MATERIAL: The only sun shade sail on the market that are made of 190 GSM virgin (Nonrecycled) HDPE material. Our virgin HDPE fabric went through 20000 hours of laboratory UV testing and it is proved to be 70 percent more durable compared to recycled HDPE under sun exposure. The fabric has been treated with UV stabilized compound, preventing shade sails from drying out, tearing and fading, significantly extending the lifespan. 2.95 percent UV BLOCKAGE BREATHABLE WOVEN FABRIC: Blocks 95 percent of harmful UV, significantly reducing the temperature and UV sunlight in shaded area during summer time, ideal for patio, swimming pool, balcony, carport etc. Breathable fabric allows water and air to go through ly, no pooling water in rainy days, resistant to both UV and water, no maintenance needed. 3.STRUCTURE DESIGNED FOR DURABILITY: All edges are constructed with heavy duty double layer reinforced stitched seams, preventing frayed edges and out of shape. Each corner ends with stainless steel Dring for easy hanging, extra heavy stitching to help the Drings strongly attached to the shade sail. 4.INSTALLATION GUIDE: Installation hardware kits are required and sold separately, each Dring will require one cable rope (DO NOT use nylon ropes, they break easily!!). Connect the other ends of cables to existing poles, trees or wall with shade sail hardware kits. High quality hardware kits and cables are recommended for performance and appearance.
