Made of 100% polyester fabric with a PU coating (160 gsm), this shade sail is healthy and safe. It is resistant to water, tears, and adverse weather conditions. The sail includes three pad eyes and comes with three 1800D wind ropes (200cm each). Robust sewing processing on each side and stainless steel D-rings on each edge firmly guarantee installation stability. UV PROTECTION: Provides up to 98% UV protection and a 90% shading rate. Shade sails lower the ambient air temperature, reducing cooling costs and energy consumption. WATER RESISTANT: Water-resistant rating: 400mm HH (water-resistant, not waterproof). The air-permeable design allows for constant fresh air circulation. Simple and safe installation with ropes is possible. It is suggested that the installation angle be 20-40 degrees to achieve maximum tension and allow rain to run off. EASY TO INSTALLATION: Measure and clean the area where the shade sail will be installed. Leave an allowance of 1.5-2 feet between the fixing point and the shade sail to accommodate hardware, hooks, or ropes. Curved sides enhance pull strength and prevent drooping, so the actual shading area will shrink slightly (tolerance of 4-6 inches per side). You can install different shade sails of various colors and sizes to create a larger shaded area. PRACTICAL & MULTIFUNCTIONAL: Widely used over patios, lawns, gardens, pools, ponds, decks, kailyards, courtyards, backyards, dooryards, parks, carports, pergolas, sandboxes, driveways, or any other outdoor area. It effectively reduces heat in your outdoor living spaces.
