PREMIUM FABRIC: Our shade sail is made of 100% polyester fabric with a PU coating, which makes it safe to use. It's highly resistant to water, tears, and adverse weather conditions, making it perfect for long-term use. The shade sail comes with three pad eyes, and we're giving away three wind ropes for easy installation. It features sturdy sewing on each side and stainless steel D-rings on each edge to ensure a secure installation. UV PROTECTION: Our shade sails can provide up to 98% UV protection and 90% shading rate, which can help reduce ambient air temperature and lower cooling costs and energy consumption. Choose our product for a safer, more comfortable outdoor experience that's also worry-free and cost-effective. WATER RESISTANT: Our shade sails are water-resistant with a rating of 400mm HH, which means they can resist water to a certain extent but are not completely waterproof. They're also air-permeable, ensuring fresh air circulation for a comfortable outdoor experience. Installation is safe and easy with rope, and we suggest a 20-40 degree angle for maximum tension and rain runoff. EASY TO INSTALL: Our shade sails are easy to install. Simply measure and clean the installation area, leaving 1.5-2ft between the fixing point and shade sail to fit hardware, hooks, or ropes. The curved sides enhance pull strength and prevent drooping, which may cause the actual shading area to shrink slightly (tolerance of 4-6 inches on each side). You can install multiple shade sails of different colors and sizes for a larger shading area. PRACTICAL & MULTIFUNCTIONAL: This shade sail is practical and multifunctional, making it suitable for use over patios, lawns, gardens, pools, decks, and more. It effectively reduces heat in outdoor living areas, making them comfortable even on the hottest days. You can install this shade sail in courtyards, backyards, parks, carports, pergolas, sandboxes, driveways, or any other outdoor area that requires shading.
